MATERIALS
Cartridge bodies are manufactured from high grade cold drawn
steel bar, with the internal working parts hardened and ground for
maximum performance and durability. Our line bodies, Hydraulic
Integrated Circuit blocks and special bodies are manufactured from
high strength, wrought aluminium bar and mild steel or stainless
steel, dependant upon the exact requirements of individual
applications. Various specialised coatings/finishes are obtainable
for when environmentally unfriendly conditions are a consideration.
For complete specifications and compatibilities, please consult our
technical department.
It is recommended that for pressures above 210 bar
(3000 psi) steel bodies are used. Whilst in most cases the
aluminium bodies are strong enough, if transient peak pressures
are encountered frequently, there is a possibility of fatigue.
PORTS
The ports on all our bodies are BSP (parallel) as standard and
range in size from 1/4" to 1 1/4". SAE ‘O’ Ring and NPT ports are
available on request.
SEALS
We use Nitrile as standard for temperatures of
-20°C to +90°C (unless otherwise stated). Viton seals are available
on request. Polyurethane seals are also available on some valves
but care must be taken in their application with regard to fluid
compatibility.
TEMPERATURE RANGES
Temperature ranges quoted throughout this catalogue relate to the
seal material only. The viscosity index of the fluid should also be
taken into account when selecting a valve, if in doubt please
contact our technical department.
FLUIDS
Recommended fluid is mineral oil.
NOTE: All our test performances are carried out by using hydraulic
oil with a viscosity of 40cSt at 40°C. For water based fluids, ie,
95/5 and 60/40 emulsion consult factory.
FILTRATION
Our valves utilise precision hydraulic components and we
recommend a filtration level of between 15 and 25 microns, to
produce a cleanliness level of BS5540/4 Class 18/13, dependant on
the type of valve used. Replace filter elements regularly, try to
avoid filter bypass condition - special attention should also be paid
to filtration when first commissioning the system or machine, when
contamination levels are high.
TAMPERPROOF DEVICES
Various tamperproofing methods are available upon request for our
range of cartridges and valves.
CARTRIDGE VALVE INSTALLATION
The correct machining of cavities to suit our range of cartridges is
critical. Cavity tools are available for sale or hire and certified
drawings are available upon request. All drawings and information
contained within this catalogue are for guidance only. Where
dimensions and actual valve usage is critical, please consult
Integrated Hydraulics for full specifications and compatibilities. We
reserve the right to alter specifications without notice or incurring
obligation.
NOTE: It is important that each designer analyses all aspects of
their application including consequences of any failure and review
the information concerning the product or system in the current
product catalogue. The responsibility for final selection rests with
the customer.
TORQUE FIGURES
The torque values stated in this catalogue are for testing purposes
only. Assembly tightening torque depends on many factors,
including lubrication, coating and surface finish. Contact main office
for further information.
ADJUSTMENT
The adjustment range and Max setting figures shown throughout
this catalogue give the design range for each valve, higher or lower
values may be attainable but should not be used without first
contacting our Engineering department. Setting must ALWAYS be
carried out using an appropriate gauge and it must NOT be
assumed that screwing an adjuster to its maximum or minimum
position will yield the maximum or minimum stated design setting
for that valve.
PRESSURE EQUIPMENT DIRECTIVE
All pressure control valves manufactured by Integrated Hydraulics
are designed to be "Pressure Accessories" in accordance with
article 3 section 3 of the Pressure Equipment Directive and Sound
Engineering Practice and sold in good faith as such. For "Safety
Accessories" as defined in article 3 section 1.4 of the Pressure
Equipment Directive please contact the UK Technical Sales
Department.

RELIEF VALVES
Graph 1 is based on a poppet style direct acting relief. The
cracking pressure is the point "A" at which the pressure over
the area of the seat is the same as the spring force. The initialopening characteristic "B" depends on the cone angle of the
poppet, the second section of the curve "C" depends on the
relationship between the design of the poppet and its
movement which is effected by the rate of the spring,
generally the higher the spring rate the steeper the gradient.
As more flow passes through the valve the relief curve will
meet the orifice curve "D".
The performance of a direct acting relief valve can be altered
by innovative poppet design. By using the flow forces to help
open the valve the effect of a high rate spring can be reduced
and the gradient be kept relatively flat.
Our brave new world of Hydraulics provides technology to
industry that is ever improving and more complex. The
demand for machines that think for themselves reducing
human error have inspired the engineering fraternity to ever greater feats of hydraulic ingenuity.
The simple directional valve has become an electronically
controlled mechanism that provides fine control to the
movement of machinery. The pump has become more
efficient by adding feed back controls in the form of pressure
compensation and load sensing, providing stable controlled
flow to a pre-determined level to reduce energy losses. Even
some actuators have built in transducers to provide position
feed back completing the loop.
It is a shame that when using this modern technology the
simpler and most important valve in a system can be as crude
as a ball on a seat. The humble relief valve takes a back seat
to the point where great effort is made not to allow this valve
its rightful roll in providing the ultimate system protection.
"Don't let it operate because it is noisy" or "we can not
guarantee that the pressure control will be consistent". "The
valve opens too soon and does not close quickly enough".
From the main system relief to the safety relief there are
valves available that are equally advanced in their innovation
and technology as the higher profile pumps, directional control
valves and actuators. The problem is that many engineers do
not understand the reasons for the different designs and their individual applications or how to assess the performance. This
article will attempt to throw some light on what is available
and where to apply the different designs.
It is true that the simplest relief valve is a ball sitting on a seat
with a spring keeping it closed until the pressure over the
area of the seat is high enough to allow the valve to open and
allow flow to pass. The flow capacity is limited by the size of
the seat and the pressure difference across the opening. To
get more flow across the valve the ball has to move further
back against the spring increasing the force and therefore the
required pressure. A basic relief valve curve will look likeGraph 1.

Figure 1 shows a section through a typical relief valve where
the poppet design allows for a relatively low pressure rise due
to increase in flow. A problem with this type of valve is that too
much flow can cause the valve to have a negative pressure
rise causing the valve to go unstable with fluctuating
pressure.
The re-seat and repeatability of the valve depends upon the
hysterisis. Internal seals cause friction against the bore as the
valve tries to close. If a seal is under pressure then the
hysterisis increases, graph 2.
A poppet valve should not leak more than 1/3 cc/min up to the
cracking pressure allowing it to be placed in a line where lowleakage is important, and performing duties such as a service
line relief.
A simple relief valve like this will give cost effective relief
protection to small systems or where the valve is not the main
pressure control but a pressure limiting device. They are not
generally suitable for high flows because the spring would
have to be of excessively high rate which would give an
unacceptably steep relief curve.
Figure 2 shows a typical pilot operated, spool type relief valve
that gives good control over varying flows. This valve, due to
its design, allows a high flow to pass with very little rise in
inlet pressure. The valve has a good re-seat and goodrepeatability due to there being no internal seals. A pilot
operated relief valve is suitable as a main pressure control but
due to the two stage design it is not suitable for safety
applications where speed of operation is important. In the
case of a rapid increase in inlet pressure the system will be
subject to a longer pressure spike than if a direct acting valve
where used.
Increasing the flow capacity of a direct acting valve by
reducing the area over which the pressure acts is possible,
figure 3 shows a differential area poppet type relief valve that
has the capability of very fast action and a high flow capacity
for its size. The internal seal is subject to inlet pressure so the
valve will display relatively poor re-seat characteristics.
The design of the poppet is such that as the valve begins to
open the flow past the poppet draws oil from the springchamber (by venturi effect over the small holes in the poppet
annulus) causing initial over opening. This removes most of
the pressure spike. The valve is therefore highly suitable as
protection for actuators.

Graph 3 shows a comparison between the typical opening
characteristics of a pilot style valve and a differential area
direct acting valve with the special poppet described above.
The difference between the opening characteristics of a pilot
style relief valve and a direct acting spool type relief valve are
shown in graph 4 & 5 respectively, graph 4 clearly illustrating
the pressure spike permitted by the pilot style valve.
Figure 4 shows a spool type direct acting relief valve. These
are suitable for low pressure systems where stable or
constant operation is required. They provide quiet operation
even with fluctuating pressures. The spool opens up a ring of
holes in the sleeve that gives a more gradual increase in flow
area than a poppet valve.
Spool valves will give between 50 and 100cc/min leakage
before they open.
The four main types of relief valve as detailed above cover
most applications but there are many variations on a theme
that give flexibility to a systems design.
Ventable relief valves, figure 5, are used to provide an
unloading function, presenting an ability to be remotely
operated and the possibility of switching between more than
one pressure.
Unloading relief valves or 'kick down' valves, figure 6, provide
an off load of pressure when the setting is reached, the valve
remains fully open until the pressure falls to zero. This
removes any force created by an actuator that could cause
mechanical damage within a system.
In order to simplify the design of a circuit and reduce its costsystem designers frequently require a valve to perform
additional functions, two such valves are shown below, figure
7 a relief valve in conjunction with bypass check and figure 8
a cross line relief valve.
When designing hydraulic systems it is important to consider
the performance of the minor components such as relief
valves. These may be minor in cost but they have a major
impact in terms of value. A poor relief valve can effect the
efficiency and life of a complete machine. From overall
pressure control to actuator protection the relief has to be of
the correct type to ensure sound performance and component
integrity.
There are also electrically controlled proportional valves
available that tie in with electronic systems. That is another
subject but they should never be allowed to replace the
humble mechanical relief valve, the correct application of
which can permit a machine to operate to its optimum
performance over a long period.

Figures based on: Oil Temp = 40°C Viscosity = 40 cStPressure acts over the differentail area between theseat and seal on the poppet. When the pressureexceeds the setting, the valve opens, allowing reliefflow to tank, washing contaminant away from the seat.
Ideal for intermittent duty as protection againstoverload or surge conditions for all types of actuators.
Very fast acting and extremely dirt tolerant.
Dirt tolerant, robust and consistent with good pressure riseto increase in flow characteristics for a direct acting valve.

SLIDING SPOOL TYPE
2
Figures based on: Oil Temp = 40°C Viscosity = 40 cSt
When inlet pressure exceeds the setting of the valve,
the pilot section opens. The pilot flow causes apressure imbalance across the main section spoolcausing it to open, allowing relief flow to tank. When‘vented’, pilot flow is referenced directly to tank,bypassing the pilot section. This flow through the ventcauses a pressure imbalance, opening the mainsection and dumping the pump at minimum pressuredrop.
To limit pressure in a system. Good for continuousduty and accurate pressure control with constant orvarying flows. The vent feature can be used withremote pilot section for a two-pressure system or toallow manual or remote ‘unloading’ of the pump.

It’s entirely natural to succumb to labels and judge a book by
it’s cover - even in the field of hydraulics. But some
components refuse to be bound by the accepted norms...
In the modern era, correct identification is paramount. Many
people carry ID cards describing them by name and
photograph. For some of us this may be acceptable but when
people try to 'pigeon hole' us we begin to react. We may like to
think that we are multi-cultured and multi skilled, yet it is
natural for us to assess things by the cover or the title. When
we do this, we miss the diverse nature of people and things
around us.
This extends to our understanding and subsequent application
of hydraulic valves. The science of hydraulics is fairly simple -
once the concepts of flow and pressure are understood
together with their effect on mechanical components, the
function of a valve or an actuator becomes clear.
Unfortunately, we do not always stop to understand what the
hydraulic function is outside of the description of a component
and therefore the limitations placed on it by documentation.
Few would advocate product being used outside of the
parameters laid down in catalogue data sheets, but the
innovative use of such product is to be applauded.
Taking Sequence valves as an example: These are used to
sequence operations by preventing flow until a pre-determined
pressure is reached. The only difference between this and a
relief valve is that the former has a spring chamber drain to aseparate port. This prevents down stream pressure increasing
the setting of the valve. Provided the inlet pressure is higher
than the setting, plus any back pressure on the drain line, the
valve will remain open, allowing flow from inlet to outlet.
There are several types of sequence valve, each with its own
performance envelope and special characteristics.
1) Direct acting spool type. (1DS60): The drawing shows a
section through a cartridge version of a direct acting
sequence valve. The pressure rises at the inlet (port 1) until
the resultant force over the spool area overcomes thespring force. This causes the spool to move back against
the spring, opening the inlet to the sequence port 2.
Provided the inlet pressure is higher than that in the
sequenced port, flow will take place from port 1 to port 2.
There is no connection between the sequence port and the
spring chamber, so as the pressure rises in the sequenced
port 2 the effective setting of the valve remains the same.
Downstream pressure has no effect on the pressure
required to keep the valve open.

With a direct acting sequence the greater the flow through
the valve, the further the spool has to move back against
the spring. This requires an increase in inlet pressure that
corresponds to the extra compression of the spring.
2) Pilot Operated Sequence valve. (1PS60): As with pilot
operated relief valves, the pilot operated sequence valve
does not require much increase in pressure differential to
pass more flow. This makes the valve more suitable for
varying flows and systems where the setting has to be close
to the maximum working pressure.
In this case the inlet pressure acts on the pilot seat area
and eventually causes the ball to move back against the
spring. This creates a flow to tank via the drain port. The
initial flow passes across the small orifice in the main spool,
causing a pressure imbalance that moves the main spool
back against a light spring. It does not take much pressure
increase to move the spool fully back, so the valve will
therefore go from fully closed to fully open over a very small
pressure increase. One disadvantage with this over the
direct acting valve is the constant flow to tank through the
pilot section of the valve.
3) Unloading Sequence Valves (1UPS100): Most sequence
valves need to maintain a higher inlet pressure than the set
pressure to keep the valve open. This, in some cases, can
be inefficient especially if the second operation is working at
a lower pressure than the setting.
The unloading sequence valve allows the valve to open fully
as soon as the setting is reached. The valve functions to
open in a similar way to the pilot operated valve except that
when the setting is reached, the spool moves back and
opens a separate hole, beyond the control orifice, in the
spool to the outlet port. This means that the pressure
behind the main spool will fall to the downstream pressure.
The inlet pressure will then fall to the same pressure plus
the pressure required to push the flow across the valve.
This can be more efficient than the standard valve.
4) Sequence Valve with Reverse Flow Check (1PSC100): It
is usual in a double-acting system for the flow to have to
pass past the sequence valve in reverse direction. It is
possible to mount a free-flow check valve around the
cartridge but it is also possible to include this extra valve in
the design. This cartridge includes the free-flow check,
making giving a more compact solution.
5) Direct Acting Sequence Valve with Reverse Flow Check
(1PSC30): For smaller flows, it is possible to have direct
acting sequence valves with free-flow checks as standard in
one cartridge. This valve is based on the overcentre valve
components.
...a look at the make up of this device
reveals that it is no more than a logic
element with an adjustable spring
force keeping it closed.
So much for boring descriptions! The fun part is making
them do what you want: The standard circuit shown in all
technical training manuals is the Guillotine circuit (figure 6).
The modern version of this machine used for cutting metal
relies on the sequence valve to make sure that the clamps
remain on while the knife does it's job.
Variations: This is valve use according to the description in the
manual. But a look at the make up of this device reveals that it
is no more than a logic element with an adjustable spring force
keeping it closed.

Controlling the pressure in, or the flow from the drain line
opens up a number of possibilities. When using a pilot
operated version of the valve, closing the drain line will close
the valve. In this way, high flows can be turned on and off by
using a small solenoid valve situated on the drain line. This can
be a normally open or closed valve with the added option of a
controllable pressure drop across the valve.
By controlling the pressure in the drain line, you can use thevalve in regenerative circuits, as below.
When extending the cylinders, oil from the 'rod' side is
prevented from passing back to tank by a check valve and is
directed towards the 'bore side' of the cylinder. The flow will
then pass through the sequence valve from the outlet to inlet.
The pressure in the outlet will be higher than the inlet, which is
higher than the set pressure of the sequence valve. The drain
line is connected upstream of the check valve so that when
retracting the cylinder, the working pressure increases the
setting of the sequence valve and keeps it closed.
The main advantage of using the sequence valve over a pilot
to close check, is that when centring the directional valve, the
pressure can be set higher than any residual pressure, thereby
preventing any un-solicited extension of the cylinder.
This kind of valve can also be used as a compensator in a
pressure compensated flow regulator circuit (figure 8), whereby
the drain line of the sequence valve is connected downstream
of an adjustable orifice and the inlet of the sequence valve
upstream, with the “sequenced” port connected to tank. The
pressure drop across the orifice is sensed by the spool in the
sequence valve. The pressure on the upstream side acts on
the spool’s nose and pressure on the downstream side acts on
SEQUENCE VALVES
OperationWhen operated fluid will flow to the
clamp cylinder closing it. At the end of
its stroke, pressure will start to rise
opening the sequence valve allowing
flow to the knife. When the directional
valve is switched to reverse the
operation flow will pass first to the knife
cylinder and only when it has reached
the end of its stroke will the pressure
rise sufficiently to open the sequence
valve on the clamp line, allowing it to
open. Return flow in both operations by-
passes the sequence valve via the built
in check elements.

the other end of the spool in the spring chamber. If flow across
the orifice increases due to a reduction in the downstream
working pressure, then the pressure drop would increase and
the sequence valve open further to by-pass excess flow to tank.
The valve will therefore seek to maintain a constant flow
irrespective of changes in working pressure.
A final example of an innovative use of a sequence valve is as a
load sense compensator (figure 9). By feeding a load sensesignal into the spring chamber, the setting of the valve can be
raised. This ensures that the pump will only ever see a pressure
equivalent to the working pressure, plus the setting of the valve.
This pressure can be limited by using a pilot relief
valve on the drain line. The flow into the spring chamber has to
be restricted for this to work, but a millimetre orifice normally
works for me!
There are many other potential uses for this valve by
using the drain port as a remote control port. Why limit the
utilisation of problem solving tools at your disposal by sticking to
a name? Hydraulic valves can be versatile. Think hydraulics
before you think description and look to performance, not tocatalogue claims. Use science and understanding first and the
product second but always consult the valve manufacturer
before going too far, as all valves will have their limitations -
some of which are far from obvious.

Direct acting sequence valves are ideal for diverting oilto a second circuit at a predetermined pressure as inclamp and drill circuits, or as a relief where the backpressure varies. By taking the drain line directly to tank,back pressure effects are negated.
As with the direct acting relief valves, when the pressureexceeds the spring force, the spool moves back,opening the inlet to outlet.

Direct acting sequence valves are ideal for diverting oilto a second circuit at a predetermined pressure as inclamp and drill circuits, or as a relief where the backpressure varies. By taking the drain line directly to tank,back pressure effects are negated.
As with the direct acting relief valves, when the pres-sure exceeds the spring force, the spool moves back,opening the inlet to outlet.

Pilot operated models are best suited for higher flowswhich may vary widely to:1. Provide ordered or sequenced series of operations
as in a clamp and drill circuit.2. Serve as a relief valve where oil viscosity or
restrictions in the downstream line would causeexcessive back pressure. The separate springchamber drain makes the sequence valveinsensitive to this back pressure. Available with orwithout built-in reverse flow checks.
As in the pilot operated relief, when the setting of the
valve is exceeded the pilot section opens. This pilotflow causes a pressure imbalance opening the mainsection and allowing flow to a secondary circuit(sequenced line).

Pilot operated sequence valves are ideal for systemswhere flows vary or the sequencing pressure is high.They provide ordered sequencing of two or moreoperations as with clamp and drill circuits. They canalso be used as relief valves where the dowmstreampressure is high or changes during operation. Bytaking the drain line directly to tank, back pressureeffects are negated.
As with the pilot operated relief valves, when the inletpressure exceeds the valve setting, the pilot sectionopens causing flow across the main spool orificeunbalancing it and subsequently moving it backagainst a light spring opening up the inlet to the oulet.The 1PSC100 has a check portion which allows freereverse flow.

An off-loading sequence valve opens fully to pass flowto a secondary cicuit when the valve pressure settingis reached. This allows flow to the secondary circuitwith a minimal pressure drop.
Inlet pressure acts on the pilot section of the valve.When the valve setting is reached, the pilot sectionopens and pilot flow causes the spool to move backuncovering the radial vent port. The main section thenopens fully with pilot flow passing through the vent.The valve remains open until flow to the sequencedport ceases and inlet pressure drops to zero.

5To maintain a constant downstream pressure lowerthan the inlet pressure. Ideal for use in two pressuresystems or to protect low pressure actuators such asbrake cylinders. Note: where reverse flow is required,see 1PAA95, page number 5-161.
This valve is normally open, allowing oil from the inletto pass through to the regulated port of the cartridge.When the regulated pressure reaches the valvesetting, the pilot section opens causing a pressureimbalance across the main spool which moves,throttling the inlet flow, preventing any further pressure
rise in the regulated line.

design, whereby the pressure acts on
an annular area, is suitable for flows up
to 300 L/min. Being of poppet type both
designs exhibit excellent leakagecharacteristics with maximum leakage
of up to 0.5 ml/min for valves up to 200
L/min capacity and up to 4ml/min for
valves with 300 L/min capacity.
The cartridge has three ports, a
cylinder port (1), a valve port (2) and a
pilot port (3). If pressure, above the setting of the valve is
applied to the cylinder port it will open as a relief. When
applied to the valve port pressure will open a low pressure
check allowing free flow into the cylinder port. Pressure
applied to the pilot port acts over a larger area on the
poppet than the area referenced to the cylinder port, so the
valve will open at a low pressure.
For most applications the relief setting should be
approximately 1.3 times higher than the maximum load
induced pressure. This ensures that with the maximum
load on the actuator the valve will remain closed until pilot
pressure is applied. The pilot pressure required to open the
valve will depend on the pilot ratio that is the ratio between
the relief area and the pilot area. The pilot pressure can be
calculated:
Pilot pressure = Valve Setting - Load PressurePilot Ratio
A typical application would entail mounting the overcentre
valve in or on the end cap of a cylinder (fig 2). The cylinder
port of the valve being connected to the full bore area of
the cylinder, the valve port to the directional control line A
and the pilot

load causes the
There are now many types of overcentre or motion control
valves available to the designer of hydraulically operated
machines, each one has its own place and specific benefits
to the user. The function of these valves can be divided
into three basic groups.
1. Load Holding; where the overcentre valve prevents the
movement of a load when the directional valve is in the
neutral position. Permitting the use of open centre
directional valves and negating leakage past the spool of
closed centre directional valves.
2. Load Control; where the overcentre valve prevents the
actuator running ahead of the pump due to the load
induced energy thereby eliminating cavitation in the
actuator and loss of control.
3. Load Safety. In the case of hose failure an overcentrevalve mounted onto or into an actuator will prevent
uncontrolled movement of the load. When a boom is used
as a crane then hose failure protection is vital as the loss
of load control could cause damage to people or property.
Each of these functions is applicable to linear or rotary
motion.
The standard overcentre valve (fig 1) can be described as
a pilot assisted relief valve with an integral free flow check.
The difference between this design of valve and a pilot
check is that the check valve will open fully as soon as thepilot pressure is sufficient to open the valve because the
only resistance to opening is the pressure locked in to the
cylinder port. With an overcentre valve the pilot pressure
has to overcome the force of the spring which is reduced
by load pressure. This ensures a gradual opening and a
metering of the flow as it passes the poppet. Integrated
Hydraulics overcentre valves consist of a poppet that seals
flow from an actuator, a check element, which permits free
flow to the actuator and a pilot section that opens the
poppet allowing flow from the actuator at a controlled rate.
There are two basic designs, each with several variants.
The direct acting design, whereby the pressure in the
actuator acts on the full area of the nose of the poppet, is
ideal for flows up to 200 L/min whereas the differential area

flow to increase then the inlet will be starved of oil and the
pressure will begin to drop at this port. The reducing
pressure will be sensed at the pilot allowing the spring to
begin to close the valve preventing load run-away. In this
way the valve will continually meter, controlling the load
throughout its movement. When the pressure needed to
move the load is higher than the pilot pressure needed tofully open the valve the only restriction produced is the
pressure drop due to flow in the fully open condition.
With the standard overcentre the spring chamber is vented
through the poppet to the valve port which creates a
problem if there are varying or high back pressures.
Pressure in the valve port increases the effective setting of
the valve by a factor equivalent to the pilot ratio plus one.
This means that if there is a standing back pressure of 50
bar with a pilot ratio of 5:1 the effective relief setting would
be increased by 300 bar. This creates problems if the
application demands a closed centre directional valve andthe utilisation of service line reliefs. The relief valves will
operate to limit inlet pressure but will not act if there is an
external load which needs to be limited. The overcentre
will not allow oil past the seat due to the back pressure
created by the service line relief valves. To overcome this
problem the part balanced 1CER series was created (fig
3).
The 1CER series overcentre valve
performs in the same way as the
standard valve under most conditions.
But the relief section of the valve is notaffected by back pressure.
The poppet is designed to balance back
pressure over two areas on the poppet.
The first is a annular area between the
seat (dia a) and the centre seal (dia b)
on the poppet which acts to open the
valve and the second at the spring end of the spool (dia c)
acting to close the valve. These areas are the same, the
poppet is therefore balanced and so pressure in the valve
line will not affect the relief performance of the valve. It
must be noted that the pilot pressure required to open the
valve is still affected on a one to one ratio by any back
pressure.
The advantage of this design is the ability to use the valve
on closed centre directional valve systems allowing service
line relief valves to operate as normal. Most other valves of
this type on the market have an atmospheric vent which
limits their use in corrosive atmospheres and are prone to
leakage.
The 1CER valve does have some draw backs in certain
applications. Because the pilot pressure is affected by back
pressure the valve can not be used in regenerative circuits
on the annular port of the cylinder. Also if used with a
meter out proportional system the constantly varying back
pressures can cause both the part
balanced and the standard valve to go
unstable. For this is the reason the fully
balanced version, 1CEB series (fig 4) is
available. In this case the spring
chamber is vented to atmosphere or to
a separate drain port.
Any back pressure therefore does not
affect the setting of the valve or the
amount of pilot pressure needed.
For the standard, Part Balanced and
Balanced valves there are various pilot ratios available to
the system designer, which is best for his circuit? A general
rule is that high pilot ratios are suitable for constant, stable
loads and low pilot ratios for unstable and varying loads.
The pilot ratio does not necessarily affect the working
pressure by much given that the normal working pressureof a system is often much higher than the pilot pressure
required to fully open the valve. If this is the case then the
piloted open pressure drop will determine the systems
efficiency.
Graph 1 shows the pressure drop curves of two valves with
different pilot ratios. The higher pilot ratio valve is more
restrictive than the low pilot ratio valve. This shows that
above a certain pressure the lower pilot ratio valve is more
efficient than the higher pilot ratio valve. It is important that
the total performance is taken into account before
specifying an overcentre valve.

OVERCENTRE
The two stage overcentre valve, 1CEL (Fig 5) has been
developed to overcome a problem which has been a
continual nuisance to designers of machines incorporating
long unstable booms. Instability problems affect many
machines, most noticeably those with high capacity
cylinders particularly in conjunction with slender booms that
are subject varying frictional forces. The best example is
the Telescopic Handler that usually has a long cylinder to
extend or retract its boom. At the end of its stroke the
pressure of the oil within a cylinder rises to the setting of
the main relief valve for that part of the system and by its
nature, the motion control valve re-seat locks in that
pressure (irrespective of any load induced pressure). Whenthe operator lowers the load, this stored energy gives the
valve the message that a heavy load is on the cylinder;
therefore it takes less pilot pressure to open. As a result,
the valve opens very quickly and allows the stored energy
to dissipate causing a momentary runaway condition, this
causes a rapid acceleration of the load that is then
checked by the motion control valve and brought under
control. The consequence of this is an initial instability as a
boom is retracted; the number of jerks will depend on the
stiffness of the system at the time of lowering. This
instability can sometimes continue through the whole of the
cylinder's stroke, its magnitude, in extreme cases, cancause severe operator insecurity or even the loss of a load.
The 1CEL valve uses two springs to control the poppet,
only the outer spring being effected by the pilot piston,
leaving the inner to generate a counterbalance
pressure. The two-stage valve has overcome
many instability problems by preventing the total
decay of the stored energy in the cylinder andstopping the valve over reacting. It allows the
pressure to fall to the counterbalance setting,
which can be adjusted dependant upon the
severity of the application. This back pressure can
also help to stiffen the boom during its movement
further through its stroke, for example when wear
pads on the box sections of a telescopic boom
create changing frictional forces. This works well
but with some systems, the backpressure created
by this valve causes problems due to the
reduction in available force. On certain machines,
when for instance a crowd cylinder is bottomed,
the oil from a slave cylinder has to be forced across a relief
valve; the boom cylinder creates an induced pressure by
virtue of its downward force. It is possible that an unloaded
boom will not lower due to the counterbalance pressure.
Also in the fully piloted open position the valve still
generates a backpressure heating the oil and creating
inefficiency.
To overcome these problems another variant is available in
which the counterbalance pressure is reduced as the pilot
pressure increases. This design has a second pilot ratio,
which acts to reduce the backpressure applied by the
centre spring. Indeed the valve can be piloted fully open,eliminating the counterbalance pressure altogether so
improving the efficiency of the system. With a primary pilot
ratio of 4:1 and a secondary ratio of 0.5:1 the initial
unloading of the stored pressure happens at a low pilot
pressure followed by a more gentle reduction as the pilot
pressure increases. The overall setting of the valve is a
combination of the outer and the inner spring forces
divided by the seat area.
The practical application of either of these valves involves
the establishing a range of acceptable settings. For
example, the requirement is for the valve to be set at 200bar (3000psi) with a counterbalance pressure between 35
and 70 bar (500-1000psi) - there are two springs within the
valve, the outer one is fixed and the inner adjustable. For
this application the outer spring would be set to give 165
bar (2400psi) and the inner adjustable
between 35 and 70 bar (500-1000psi).
This would give the valve an adjustable
range of 165-235 bar (2400-3400psi).
Given a pilot ratio of 6:1 or 4:1
depending on the type this extra
pressure setting would have little effect
on the pilot pressure needed to open
the valve during normal operation.

Graph 2 shows a typical recorded instability picking up
machine frequencies and getting worse and Graph 3
shows the counterbalanced overcentre valves preventing
the problem getting worse, dampening
out the initial instability and the
counterbalance pressure falling as the
pilot pressure increases.
The zero differential range of load
control valves 1CPB (fig 6) have been
designed with 'BoomLoc' hose rupture
valve applications in mind. Typically the
valve is piloted open from the hydraulic
remote control operating the main
directional spool valve. By setting the overcentre to open
just after the main valve it will control the flow rate at low
speed but as the overcentre opens more rapidly than the
directional valve the directional valve will control the flow
rate at higher speeds. It is a pilot operated metered poppet
valve. The poppet seals against a tapered seat, as the pilot
pressure increases the poppet will move off the seat. Flow
is dependant upon the axial movement of the poppet which
in turn is dependant upon the force exerted by pilot
pressure balanced by that exerted by the spring. The
poppet is hydraulically balanced so this valve is unaffected
by valve line AND cylinder
pressure but it will not provide any
relief function. If over pressure,
shock or thermal relief are
required a second relief element
is required.
The successful application of
motion control valves, particularly
in areas that are demanding
involves the anticipation and
resolution of numerous factors
only some of which can be
discussed in this article. Motion
control valves are adjustable, areavailable in several pressure
ranges with many pilot ratio
options. Most of the valves fit in a
common cavity (the exception
being the fully balanced, 1CEB
and zero differential, 1CPB versions when required with an
external rather than an atmospheric vent) and are available
in sizes from 30 to 300 L/min. The
flexibility of cartridge valve
technology can therefore be easily
applied to bring stability. The
standard range of valvesdescribed here can be used to
solve the vast majority of motion
control problems and we are
constantly developing new valves
that will further improve stability
and load control.

The 1CER series overcentre valve performs all dutiesof a regular overcentre but is able to relieve and stayopen irrespective of downstream pressure. Thisenables the valve to operate when used with a closedcentre directional valve which has service line reliefs.
The poppet is pressure balanced, preventing reliefsetting increase due to back pressure.
The check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but the
pressure required to open the valve and allowmovement depends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and startactuator movement can be calculated as follows:
Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot Ratio

Overcentre valves give static and dynamic control of
loads by supplying a counterbalance pressure to the
actuator. They prevent runaway in the event of hose
burst and hold the load with minimal leakage.
The pressure balanced valve is unaffected by back
pressure, allowing service line reliefs to operate andfor the valve to be used in regenerative or proportional
valve systems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible to give
maximum protection.
Single overcentre valves control unidirectional loadssuch as in aerial platforms, cranes or winches and
dual overcentres are suited to bi-directional motion
such as wheel motor applications or cylinders going
over centre.

APPLICATION
FEATURES
Zero differential overcentre valves give static anddynamic control of loads by supplying a restriction toflow related to the opening of the valve created by thepilot pressure.The valve is used in conjunction with a remote pilotsource to provide hose failure protection, load controland load holding functions.
If over-pressure or shock pressure protection isrequired then a separate relief valve should be used.
The cartridge fits a simple cavity allowing quick, easyfield service reducing down time.Hardened poppet and seat provide for long leak freeperformance.Fits standard 30 litre overcentre cavity.
OPERATION
The check section allows free flow into the actuator thenholds and locks the load against movement. By theapplication of pilot pressure to the pilot port the poppetmoves back against the main spring opening thecylinder port to the valve port. The metering characteristicof the valve is controlled by the rate of the spring, the seatangle and the pilot pressure applied.
Due to the balanced poppet design load inducedpressure will not open the valve and once open valve portpressure will not increase the pilot pressure required to
keep the valve open.
*For applications above 210 bar please consult our technical department or use the steel body option.

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motorapplications or for cylinders going over centre.

Overcentre valves give static and dynamic control ofloads by supplying a counterbalance pressure to theactuator. They will stop runaway in the event of hoseburst and hold the load with minimal leakage.
The pressure balanced overcentre relief setting is
unaffected by back pressure, enabling the valve to stayopen when the valve port pressure rises. This willallow service line reliefs to work normally and will alsoallow the control of regenerative or proportionalsystems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible, using amachined cavity into the actuator or a suitablemachined body, either gasket or line mounted.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motor
applications or for cylinders going over centre.
The check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allowmovement depends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and startactuator movement can be calculated as follows:
Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot Ratio

Zero differential overcentre valves give static anddynamic control of loads by supplying a restriction toflow related to the opening of the valve created by the
pilot pressure.The valve is used in conjunction with a remote pilotsource to provide hose failure protection, load controland load holding functions.
If over-pressure or shock pressure protection isrequired then a separate relief valve should be used.
The cartridge fits a simple cavity allowing quick, easyfield service reducing down time.
Hardened poppet and seat provide for long leak freeperformance.
OPERATION
The check section allows free flow into the actuator thenholds and locks the load against movement. By theapplication of pilot pressure to the pilot port the poppetmoves back against the main spring opening thecylinder port to the valve port. The metering characteristicof the valve is controlled by the rate of the spring, the seatangle and the pilot pressure applied.
Due to the balanced poppet design load inducedpressure will not open the valve and once open valve portpressure will not increase the pilot pressure required tokeep the valve open.

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motorapplications or for cylinders going over centre.

The check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allow move-ment depends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and startactuator movement can be calculated as follows:

Overcentre valves give static and dynamic control ofloads by supplying a counterbalance pressure to theactuator. They prevent runaway in the event of hoseburst and hold the load with minimal leakage.
The pressure balanced valve is unaffected by backpressure, allowing service line reliefs to operate andfor the valve to be used in regenerative or proportionalvalve systems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible to givemaximum protection.
Single overcentre valves control unidirectional loadssuch as in aerial platforms, cranes or winches anddual overcentres are suited to bi-directional motionsuch as wheel motor applications or cylinders goingover centre.
SPECIFICATIONS
APPLICATION
Cartridge is economical and fits simple ‘dual purpose’cavity. Allows quick, easy field service - reduces downtime. Overcentre is interchangeable with 120 litres/minpilot check cartridge. See page 7-171.

APPLICATION
FEATURES
Zero differential overcentre valves give static anddynamic control of loads by supplying a restriction toflow related to the opening of the valve created by thepilot pressure.The valve is used in conjunction with a remote pilotsource to provide hose failure protection, load controland load holding functions.
If over-pressure or shock pressure protection isrequired then a separate relief valve should be used.
The cartridge fits a simple cavity allowing quick, easyfield service reducing down time.Hardened poppet and seat provide for long leak freeperformance.
OPERATION
The check section allows free flow into the actuator thenholds and locks the load against movement. By theapplication of pilot pressure to the pilot port the poppetmoves back against the main spring opening thecylinder port to the valve port. The metering characteristicof the valve is controlled by the rate of the spring, the seatangle and the pilot pressure applied.
Due to the balanced poppet design load inducedpressure will not open the valve and once open valve portpressure will not increase the pilot pressure required to
keep the valve open.

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motorapplications or for cylinders going over centre.

The 1CEL overcentre valve performs all duties of aregular overcentre but maintains a counterbalancepressure to provide dampening to cylinders whenthere is a rapid loss in stored pressure. Thiscounterbalance pressure reduces as the pilotpressure increases. Typical applications includeextension cylinders on telescopic handlers where it isimportant to have a smooth operation when retractingfrom full extension.

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when tehload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motorapplications or for cylinders going over centre.

Overcentre valves give static and dynamic control ofloads by supplying a counterbalance pressure to theactuator. They prevent runaway in the event of hoseburst and hold the load with minimal leakage.
The pressure balanced valve is unaffected by backpressure, allowing service line reliefs to operate andfor the valve to be used in regenerative or proportionalvalve systems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible to givemaximum protection.
Single overcentre valves control unidirectional loadssuch as in aerial platforms, cranes or winches anddual overcentres are suited to bi-directional motionsuch as wheel motor applications or cylinders goingover centre.

Overcentre valves give static and dynamic control ofloads by supplying a counterbalance pressure to theactuator. They prevent runaway in the event of hoseburst and hold the load with minimal leakage.
The pressure balanced valve is unaffected by backpressure, allowing service line reliefs to operate andfor the valve to be used in regenerative or proportionalvalve systems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible to givemaximum protection.
Single overcentre valves control unidirectional loadssuch as in aerial platforms, cranes or winches anddual overcentres are suited to bi-directional motionsuch as wheel motor applications or cylinders goingover centre.

APPLICATION
FEATURES
Zero differential overcentre valves give static anddynamic control of loads by supplying a restriction toflow related to the opening of the valve created by thepilot pressure.The valve is used in conjunction with a remote pilotsource to provide hose failure protection, load controland load holding functions.
If over-pressure or shock pressure protection isrequired then a separate relief valve should be used.
The cartridge fits a simple cavity allowing quick, easyfield service reducing down time.Hardened poppet and seat provide for long leak freeperformance.
OPERATION
The check section allows free flow into the actuator thenholds and locks the load against movement. By theapplication of pilot pressure to the pilot port the poppetmoves back against the main spring opening thecylinder port to the valve port. The metering characteristicof the valve is controlled by the rate of the spring, the seatangle and the pilot pressure applied.
Due to the balanced poppet design load inducedpressure will not open the valve and once open valve portpressure will not increase the pilot pressure required to
keep the valve open.

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
These dual overcentre valves also contain a brakerelease shuttle valve which ensures that pressure isapplied to a brake release circuit regardless ofwhether pressure is applied to ports V1 or V2. Thesemultifunction valves are normally used for the staticand dynamic control of systems using motors or semi-rotary actuators.

The check section allows free flow into the actuator
then holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allowmovement depends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and startactuator movement can be calculated as follows:
Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot Ratio

LOAD CONTROL / HOLDING VALVES
HOSE BURST PROTECTION (REF: ISO8643)
1CEBL SERIES
These valves comply withInternational Standard ISO8643 for
hydraulic excavators and backhoeloaders incorporating servo pilotsystems. The valves’ function is toprevent uncontrolled lowering of theboom in the event of hose rupture.Closure of the valve is activated bybringing the main control valve leverto the neutral position.
By separating the relief and pilotfunction into two individual cartridges, thepilot cartridge has no relieving function,hence any load on the valve does notaffect its opening characteristics.
Consequently, the valve will alwaysopen at the same pilot pressure/joystickposition, regardless of load. This featureenables the valve to be tuned to open inharmony with the machine’s own maincontrol valve, giving better control.
The pilot cartridge is generally set todwell 1 to 2 bar behind the maincontrol valve, therefore theIntegrated Hydraulics valve takescontrol in the event of hose failure.
When fitted to the arm/dipper
cylinder, this dwell behind the maincontrol valve prevents accelerationwhen ‘arm down’ is selected.
Fig. 1 and 2 show typical circuits utilis-ing these components.
Line mountings or SAE flangemountings are available for directfitment to the actuator. Where linemounted models are used it isessential that steel pipes are usedbetween the valve and the actuator.
All components are manufactured insteel and are electroplated forcorrosion protection.

BOOMLOC VALVES (DESIGNED & TESTED TO ISO8643
machine would not necessarily work on another. Due to the
unique seat and poppet arrangement in the 1CPB series
cartridges used in their "BoomLoc" range and the flexibility of
the cartridge valve design "BoomLoc" valves can be tailoredto suit most directional valves and so provide exceptionally
fine control. A level of control that is particularly desired for
levelling and grading, which can reduce (if not eliminate) the
"washer board" effect frequently found when other valves are
used. This fine control also has the benefits of enabling the
operator to accurately position loads during craning
operations.
Reduced installation costs can be realised using these
"BoomLoc" valves as they use a simple direct SAE mounting
to cylinder. In order to minimise stock requirements we have,
where possible designed the cylinder port face to be suitable
for both SAE3000 and 6000 flanges. A pilot bleed port is
available on most valves simplifying installation further.
Service costs are also minimal, in the unlikely event of a
BoomLoc valve being damaged, repair usually just involves
the replacement of one or two self-contained cartridges. What
is more there is rarely any need to remove the block from the
cylinder when changing the cartridges - reducing the risk of
the ingress of contaminants and the down time of the
machine. Spares inventory is frequently reduced as the same
two, standard, off-the shelf cartridges (albeit set differently)
are often used on a wide range of machines.
OPERATION
Upon operating the control to raise a boom, pilot pressure
from the hydraulic remote control unit operates the
appropriate spool in the main directional valve, permitting flow
to the cylinder. At the cylinder the flow passes through our
Hose Rupture Valve (HRV) check sections with minimal
pressure loss and enters the cylinder. (The fluid from the
other end of the cylinder flows directly to tank via the main
control valve).

VALVE
Free Flow to Cylinder
The requirement for hose rupture protection on mobile plant is
enshrined in law in many territories and likely to become so in
many others. ISO8643 requires that, in the event of a hose
failure while lowering a boom it should not accelerate to morethan twice its original speed with the control lever held in the
same position. Additionally the valves introduced to achieve
this should not unduly effect the operation of the machine to
which they are fitted. (The current 100% maximum increase
may be reduced to 75% in the future). If a hose were to fail
while a boom is lifting or static the load should be held in
position. We have developed a range of hose rupture valves,
designated "BoomLoc", that are designed to meet the
stipulations of ISO8643 and can be applied to numerous
different machines.
BoomLoc valves are reliable because they make use of
standard off the shelf components that have been field
proven, in most cases for many years. All our cartridge valves
are manufactured to a high standard with moving parts
hardened and precision finished to give a long trouble free
service life. Their performance is predictable so set up and
development times can be dramatically reduced even when
applied to a new system. In service the valves perform as
intended with cartridges having been tested to over 1,000,000
cycles in our development department and having been used
for many years in the field. When operating under normal
circumstances, i.e. with hoses intact, BoomLoc valves offer
high efficiency, as the hydraulic fluid is free to pass through
the valve to the cylinder with negligible pressure loss. And byselecting the most appropriate package to match the
performance of any given directional valve pressure losses in
the return direction can be kept to an absolute minimum.
BoomLoc valves can provide a very compact solution. The
valve should be mounted on the cylinder, either directly onto
its port or connected to the port by rigid tube, so space can be
quite restricted. Using Integrated Hydraulics Boomloc valves
unique design potential to the full, transfer plates, commonly
employed to permit the fitting of more bulky valves can often
be eliminated. The block can be designed to suit the
customer's installation and can even be done away with if thecartridge valves are incorporated into cylinder end caps thus
dramatically reducing the space requirement and the cost of
the overall package. Furthermore additional features can be
incorporated in the block making the machine more versatile.
To achieve the desired protection without adversely effecting
the operation of the machine it requires the accurate
balancing of the hose rupture valve and the main directional
valve. In order to work effectively the opening of the hose
rupture valve should, ideally, lag behind that of the directional
valve and the difference in pressure drop should remain
constant throughout the operating flow range. To achieve this
the hose rupture valve should be matched to the system in
which it is employed, a set up that works on one type of
7/25/2019 Cartridge Valves Ct 198974
http://slidepdf.com/reader/full/cartridge-valves-ct-198974 141/312
When the control lever is returned to neutral, the check valves
in the HRV close and any return flow is blocked, the load is
now locked in position.
Cavitation and excessive pressure in the boom cylinder,
(bottom end circuit), is prevented by an overload relief and
make up check, located in the HRV. Flow being returned to
tank via the main control valve port relief.
When the control lever is pushed forward to the boom lowerposition, pilot pressure from the hydraulic remote control unit
operates the appropriate section of the main directional valve,
opening flow from the cylinder return line to tank. At the same
time the pilot pressure opens the main poppet of the HRV,
thus allowing oil to flow from the bottom end of the cylinder to
the return line. The rate at which the boom descends is
dependent on the position of the poppet in the HRV and the
spool in the main directional valve, So in the event of a total
hose failure the HRV will prevent the boom accelerating
above twice its original speed. As the flow rate is now dictated
by the pressure drop across only the BoomLoc valve.
Releasing the control lever will permit the poppet in the
BoomLoc HRV to close stopping the boom from further
descent.
BOOMLOC VALVES SET-UP PROCEDURES
For reasons of safety it is recommended that ALL
adjustments to the Hose Rupture Valve be carried out
with the bucket rested on the floor.
Unless otherwise requested the cartridges are preset to 350bar (relief cartridge) and 10 bar (pilot catridge, part number
1CPB** or 1CPBD**). The pilot valve will normally require
adjustment, but the relief setting of 350 bar is generally
suitable for most applications and ensures the maximum
protection of the cylinders. Check the maximum pressure of
the system and adjust the relief valve if required. Prior to all
adjustment ensure pilot line has been fully bled. This can be
achieved by operating the joystick to either roll in or lower the
respective cylinder and opening the bleed port on the Hose
Rupture Valve. In cases where no "BLEED" port is provided,
disconnect the pilot hose from the Hose Rupture Valve and
running it to a suitable container should suffice.
Relief Valve setting: The relief setting of 350 bar has been
calculated to meet most systems but can be adjusted to
individual requirements. It is advised that the setting be
between 10 and 20% higher than the main control valve. To
increase setting, screw the adjuster clockwise to increase
pressure at a rate of approximately 65 bar per full turn. To
decrease setting, screw the adjuster anti-clockwise to
decrease pressure at the same rate.
Pilot Cartridge setting: To successfully set the pilot cartridge
pressure, two 400 bar and one 50 bar gauges need to be
used. On the Hose Rupture Valve, connect one 400 bargauge to the "E" port where provided (or the cylinder port if no
“E” port ) and the other 400 bar gauge in the valve inlet line
“V”, and connect the 50 bar gauge in the pilot line "P".
The procedure can be related to both the Arm cylinder and
the Boom cylinders but for the ease of explanation, the
following procedure is for Boom cylinders only.
1 Fully swing out Arm cylinder. Raise Boom to full extension
and at the end of its stroke record the pressure in the valve
and cylinder gauges.
2 To check setting, slowly move joystick to lower Boom.
When the gauge in the valve line starts to fall, it is a signalthat the main control valve has started to open, at this point
note the setting in the pilot line, typically 8 bar.
3 Continue to slowly operate the joystick and note the reading
in the pilot line when the gauge in the cylinder line starts to
fall. This indicates the setting of the pilot cartridge
(1CPB(D), typically 10 bar.
It is recommended that the Pilot Cartridge should dwell
between 1.5 and 2 bar behind the Main Control Valve. If the
pilot valve is set too low, pressure at "E" falls before "V" -
adjust pilot valve clockwise.
If the difference between 2 and 3 above is greater than 2 bar
- adjust the pilot valve anti-clockwise.

6These overcentre valves are suitable for use on theboom and dipper cylinders of an excavator to help themanufacturer or user comply with standard ISO8643.
They were designed to give relief, load holding andhose failure protection to systems where a pilotsystem controls the directional valves.
By connecting the hose rupture valve pilot in parallelwith the directional spool valve pilot, and adjusting the
opening characteristics of the hose rupture valve tosuit that of the spool valve “BoomLoc” may be set soas not to interfere with the normal operation of themachine. Fine adjustment of the pilot pressurepermits the optimum setting to be made in differingoperating systems.
Both the pilot and the relief sections are unaffected bybackpressure, enabling the service line relief’s tooperate normally. In the event of hose failure, thecontrol will be passed from the main spool to the“BoomLoc” valve, maintaining control of the cylinder.
Regardless of the load the pilot pressure requirementremains constant as the valve is unaffected by load
induced pressure, the poppet being fully balanced withzero differential area.
SPECIFICATIONSAPPLICATION
This is a compact design with good dirt tolerance.Hardened poppets and seats provide excellent loadholding characteristics with all the advantages of thecartridge insert.

They were designed to give relief, load holding andhose failure protection to systems where a pilotsystem controls the directional valves.
By connecting the pilot line in parallel with the spoolvalve pilot, the low pilot pressure allows the valve toopen just prior to the spool valve, ensuring that thevalve does not interfere with the normal operation ofthe machine. Fine adjustment of pilot valve allows fordiffering operating systems.
Both the pilot and the relief sections are unaffected byback pressure, enabling the service line reliefs tooperate normally, without interfering with the spoolvalve control as it meters the return flow. In the event ofhose failure, the control will be passed from the mainspool to the overcentre valve, maintaining control of thecylinder.
As the pilot valve is operated on a zero differential,induced load pressure does not alter the preset pilotpressure.

1SE SERIES OVERCENTRE VALVE
PILOT ASSISTED RELIEF WITH CHECK
1SE30
Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directionalcontrol valves are used, will allow thermal expansion
relief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directional for motorapplications or for cylinders going over centre.
The check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pliot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allowmovement depends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and start
actuator movement can be calculated as follows:Pilot Pressure = (Relief Setting) - (Load Pressure)

1SER SERIES OVERCENTRE VALVE

1SER30
The 1SER series overcentre valve performs all dutiesof a regular overcentre but is able to relieve and stayopen irrespective of downstream pressure. Thisenables the valve to operate when used with a closedcentre directional valve which has service line reliefs.
The poppet is pressure balanced, preventing reliefsetting increase due to back pressure.
The check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but the

1SEB SERIES OVERCENTRE VALVE
FULLY BALANCED - PILOT ASSISTED
1SEB30
Overcentre valves give static and dynamic control of loads by supplying a counterbalance pressure to theactuator. They prevent runaway in the event of hoseburst and hold the load with minimal leakage.
The pressure balanced valve is unaffected by backpressure, allowing service line reliefs to operate andfor the valve to be used in regenerative or proportionalvalve systems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible to givemaximum protection.
Single overcentre valves control unidirectional loadssuch as in aerial platforms, cranes or winches anddual overcentres are suited to bi-directional motionsuch as wheel motor applications or cylinders goingover centre.

1SE SERIES OVERCENTRE VALVE
PILOT ASSISTED RELIEF WITH CHECK
1SE90
Overcentre valves give static and dynamic control of loads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motor or rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, or contained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform or crane and dual overcentre valves are used for controlling loads in both directions for motor applications or for cylinders going over centre.

1SEB SERIES OVERCENTRE VALVE
FULLY BALANCED - PILOT ASSISTED
1SEB90
Overcentre valves give static and dynamic control of loads by supplying a counterbalance pressure to theactuator. They will stop runaway in the event of hoseburst and hold the load with minimal leakage.
The pressure balanced overcentre relief setting is
unaffected by back pressure, enabling the valve to stayopen when the valve port pressure rises. This willallow service line reliefs to work normally and will alsoallow the control of regenerative or proportionalsystems.
The overcentre valve should be mounted either into,onto or as close to the actuator as possible, using amachined cavity into the actuator or a suitablemachined body, either gasket or line mounted.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform or crane and dual overcentre valves are used for controlling loads in both directions for motor
applications or for cylinders going over centre.
The check section allows free flow into the actuator then holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The relief section is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allowmovement depends on the pilot ratio of the valve. For optimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and startactuator movement can be calculated as follows:
Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot Ratio

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directional
control valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motorapplications or for cylinders going over centre.

The total pressure setting will normally beset at 1.3 times the load induced pressure. Thecounterbalance pressure reduces as the pilotpressure increases.

Pilot check valves allow flow to pass in one direction,with a low pressure drop, then prevent reverse flow
until pilot pressure is applied. There are many
applications for this valve type, the most commonbeing to lock and hold a cylinder, or another hydraulic
actuator, in position.
The 4CK30 is a small cartridge valve and is ideally
suited for fitting directly into a cylinder, giving economy
of installation, direct control of cylinder movement and
ease of servicing.
FEATURES
Pressure on the valve port causes the poppet to lift
against the spring force, allowing the flow to the
cylinder port. Reverse flow is prevented by the poppetreseating. Pressure applied to the pilot port willovercome the cylinder port pressure and lift the poppet
from its seat, allowing flow from the cylinder to valve
port.

4CKD SERIES CHECK VALVES
PILOT OPERATED WITH DECOMPRESSION STAGE
A decompression pilot check can be used in most
applications that use a standard pilot operated check.Free flow in one direction and load holding in the other.
The decompression feature allows locked-in pressure
to decay in a controlled fashion, reducing hydraulicnoise and instability caused by the rapid loss of energyfrom the actuator. The valve is effective in clamping
circuits and when used with intensifiers or when there
are high load induced pressures.
The ball and poppet are held onto their respective
seats by spring force, ensuring positive sealing as
long as the pressure on port 1 is equal to or greater
than the pressure on port 2. As soon as the pressure
on port 2 exceeds the pressure on port 1 plus the
spring force, the valve opens from 2 to 1. In order to
pass flow in the reverse direction, pilot pressure must
be applied to port 3. Once this reaches the required
level, the pilot piston acting on the pin in the centre of
the poppet lifts the ball off its seat, enabling the fluid to
decompress and thus reducing the load pressure
acting on port 1. As the load pressure decreases, the
pilot pressure required to open the main stage also
decreases and when the correct pilot pressure is
reached, the main stage poppet is lifted off its seat by
the advancing pilot piston, allowing full flow from 1 to 2.
When calculating the pilot pressure, it must beremembered that any back pressure on port 2 will
cause this to increase on a 1:1 ratio.
Figures based on: Oil Temp = 40°C Viscosity = 40 cSt
Decompression stage reduces hydraulic noise on rapid
loss of pressure. Precision ground ball and hardened &
ground poppet ensure positive sealing and long, trouble-
free working life.
This valve is directly interchangeable with the 4CK90 check
valve and 1CE*90 series overcentre valve.

Pilot check valves allow flow to pass in one direction,
with a low pressure drop, then prevent reverse flow
until pilot pressure is applied. There are many
applications for this valve type, the most commonbeing to lock and hold a cylinder, or another hydraulic
actuator, in position.
The 4CK120 cartridge valve is ideally suited for fitting
directly into a cylinder, giving economy of installation,
direct control of cylinder movement and ease of servicing.
FEATURES
Pressure on the valve port causes the poppet to lift
against the spring force, allowing flow to the cylinder
port. Reverse flow is prevented by the check reseating.
Pressure applied to the pilot port will overcome the
cylinder port pressure and lift the poppet from its seat,allowing return flow.

Pilot check valves allow flow to pass in one direction,
with a low pressure drop, then prevent reverse flow
until pilot pressure is applied. There are many
applications for this valve type, the most commonbeing to lock and hold a cylinder, or another hydraulic
actuator, in position.
A pilot relief valve will protect the cylinder and hoses
from thermal expansion of the hydraulic fluid.
FEATURES
Pressure on the valve port causes the poppet to lift
against the spring force, allowing the flow to the
cylinder port. Reverse flow is prevented by the poppet
reseating. Pressure applied to the pilot port will
overcome the cylinder port pressure and lift the poppet
from its seat, allowing flow from the cylinder to valveport.
In dual pilot check valves, each pilot section is cross
connected to the opposite line giving automatic pilot
operation in both directions. When the pressure in C1
rises above the setting of the relief valve, the relief
valve will open, allowing flow to the V1 port, relieving
pressure on the cylinder.

7Used to lock a cylinder or part of a circuit and preventreverse flow until pilot pressure is applied. For use inhigh pressure, low flow circuits and circuits requiringdecompression. Can be used in conjunction with the1T16 pressure intensifier. See page 16-121.
In free flow direction, flow through inlet unseats thepoppet and flows out of the cylinder port. When thecontrol valve is centred the load is locked. When pilotpressure is applied the piston unseats the smallpoppet in the centre of the main poppet. Flow throughthis small seat area lowers the load or locked
pressure (decompression stage). With load pressurereduced the main poppet is then piloted fully openallowing reverse flow.

Pilot to close check valves allow flow to pass in onedirection, with a low pressure drop to prevent reverse
flow. When the pilot pressure is applied, flow isprevented in either direction. The pilot ratio of 2:1allows a lower pressure in the pilot line to hold thevalve closed.
The 5CK30 series are check cartridges ideally suitedfor fitting directly onto a cylinder. They are ideal for usein regenerative circuits, accumulator dump circuits andin control of cylinders or motors.
Pressure on the cylinder port causes the ball to lift againstthe spring force, allowing flow through to the valve port.
Reverse flow is prevented by the ball reseating. Pressureapplied to the pilot port will hold the ball against its seat,preventing flow from cylinder to valve.
OPERATIONAPPLICATION

FEATURES
Easy flow path gives good pressure to flow characteristicsand hardened components ensure a long working life.Cartridge construction allows installation in actuators,manifold blocks and Hydraulic Integrated Circuits. They fitthe same cavities as the 4CK pilot to open check valves,so care should be taken when selecting the valve.

ATTACHMENT VALVES
In order for users of mobile plant to operate
auxil iary equipment from the hydraulic
system of the carr ier so avoiding the need
for an auxil iary power source accuratecontrol of the f low and pressure is vital . The
requirements of various attachments wil l
dif fer both by type and manufacturer and the
carr iers operating system wil l also vary.
The following article charts the progress of several variants
that solve the problem of differential pressure requirements
whilst at the same time offering additional benefits. The
standard Priority Flow Regulator (2FP) is the basis for a
range of valves designed to provide priority flow and a
bypass flow which can be used at different pressures. The
setting is controlled by a simple needle valve with a
compensating spool restricting the flow to the port working
at the higher pressure thus maintaining the controlled flow
from the regulated port. Before describing the variations in
design and application it is necessary to understand the
workings and performance of the standard priority style
flow regulator as the normal operation of the variants
(2FPH series) are the same.
2FP SERIES PRIORITY FLOW REGULATOR
The flow from the pump enters the inlet port and passes
across the needle valve, then on through the sleeve, past
the compensating spool and out through the regulated port.
The passage of oil across the needle valve creates apressure difference which is sensed across the
compensating spool. When the flow is sufficient to create a
7 bar pressure difference across the needle valve the
compensating spool will begin to move uncovering the
radial holes in the sleeve and opening up a path to the
bypass port. Oil will therefore begin to pass to the bypass
line. If the flow tries to increase across the needle valve,
and so to the regulated port, there will be an increase in
pressure difference sensed by the compensating spool
causing it to move further against the spring, open further
the line to the bypass port and limiting the flow to the
regulated line. If the inlet flow falls below the setting of thevalve the pressure difference across the needle valve will
drop below the 7 bar needed to keep the bypass line open
therefore the priority line is always satisfied before the
bypass line opens. Changes in operating pressure on
either of the two outlets will alter the inlet pressure to the
higher of the two pressures (plus the control pressure
which is 7 bar). If the working pressure in the regulated line
is higher than that in the bypass line then the tendency
would be for the flow to try to take the easy way out and
flow down the bypass line. This would detract from the flow
passing across the needle valve lowering the pressure
difference causing the compensating spool to shift,
increasing the restriction to the flow to the by-pass and
reducing the restriction of the flow to the regulated line. In
this way the compensating spool will maintain the regulated
or priority flow at a constant level.
If the working pressure in the bypass line is higher than
that in the regulated line then there would be a tendency
for the flow to increase through the regulated line,
increasing the flow would increase the pressure difference
across the needle valve and cause the compensating spool
to metre the regulated line.
During the normal operation of any system utilising this
type of valve both the regulated and the bypass pressures
will be constantly altering causing the compensating spool
to metre. The valve will maintain the priority flow within +/-10% of its setting throughout its range. The largest
movement in flow will occur when pressure differential is
transitional, the higher pressure varying between the
bypass and regulated ports, this causes the compensating
spool to move from metering one ring of holes in the
sleeve to the other. (See graph)
2FPH55, 95 & 195
The 2FPH series of flow regulators are based around the
standard priority flow controls but with the addition of a
pressure control and a solenoid vent both causing all of the

flow to pass to the bypass port.
This type of flow regulator lends it's self to attachment
circuits where a piece of ancillary equipment needs a
controlled flow with a pressure limitation which is lower
than the maximum working pressure of the carrier.
They were originally developed for Hammer circuits where
the hydraulic hammer requires a constant flow for efficient
operation. There was also a pressure limit for safe
operation which was well below the normal working
pressure of Excavators. It was also necessary to maintain
the other functions on the carrier to enable movement of
the arm and the pecking action needed to fire the hammer
into life. This was achieved by control of the springchamber pressure in the standard priority flow regulators.
The dampening orifice in the spool on these valves
enabled the use of pilot valves which were mounted
directly into the spring housing giving a very neat, compact
solution. In normal operation these valves behave just as
the 2FP range but if the pressure in the bypass circuit
exceeds the setting of the relief valve ("A" in Fig 2) the
compensator spool reacts by cutting ALL flow to the
Regulated port, only when the pressure in the by-pass port
drops below the setting of the relief will normal flow be
resumed. When using this type of valve with a hammer it is
an advantage to have the hammer turn off if the operatordecides to put too much pressure on down stroke in an
attempt to increase the speed of operation. In this way
potential damage to the hammer is avoided. Energizing the
Solenoid valve ("B" in Fig 2) has the same effect, venting
one side of the compensator spool and causing it to block
flow to the regulated port.
The range included three sizes which corresponded to the
three larger sizes of priority flow regulator with rated
regulated flows of 55, 95 and 195 L/min. At the time this
covered the majority of the applications.
2FPH250/350
It was not long before the operators of Excavators realised
that a power take off provided by this sort of valve enabled
the use of more varied attachments without the extra
power source and the associated pipe work. The
disadvantage with the original valves was that the pressuresense for limiting the regulated pressure was referenced to
the inlet. This meant that if the inlet pressure rose higher
than the setting of the attachment then the valve would
switch all of the flow to the bypass starving the attachment
of oil. The valve therefore became limited to hammers and
other high pressure attachments. The other alternative was
to set the pressure control valve in the flow regulator high
and fit an external relief valve on the regulated line.
Developments in Excavator control systems and also in the
attachments demanded that a new design of valve was
necessary. The two new additions to the range have been
designed to accommodate the attachments which may
require the bypass pressure to work higher than the
regulated pressure while maintaining the function of the
attachment. The pressure limit to the regulated line is
achieved by using a pilot unloading valve ("A" in Fig 3)
which senses pressure from the regulated line only. This
allows the bypass pressure to rise above the regulated
setting without affecting the operation of the attachment.
Again in normal operation these valves behave just as the
2FP range but if the pressure in the regulated line rises
above the setting of the unloading valve it will vent the
spring chamber causing the compensator spool to shift
cutting the flow to the regulated port. The resultant lack offlow will cause the pressure to drop, the unloading valve to
close and the compensator to open the regulated port
again. In practice this all happens smoothly and balance is
maintained. By operating the pilot solenoid valve ("B" in
Fig 3) and venting the spring chamber to tank, all of the
flow will pass to the bypass port. While the valves will work
perfectly adequately with hammers it will also work with
generators, compactors, crushers and flail mowers. With
this design it was also felt that increases in regulated flow
were desirable hence the 250 and 350 L/min regulated
flow rating.

The 2FPH series of priority flow regulator valves givesfull control of regulated flow (see the 2FP series) plusremote selection of priority flow and adjustablepressure limitation of the regulated line.
Inlet flow passes through the adjustable orifice and theradial holes in the spool/sleeve assembly then out ofthe regulated port. The pressure drop across theorifice is sensed at each end of the spool, producing a
force which, at the required flow rate, overcomes thespring force. The resultant movement of the spoolregulates the flow by opening the radial valve ports tothe bypass port and closing the regulated flow ports.The solenoid valve vents the spring chamber to a drainline and in its NORMAL (de-energised) mode all inletflow is diverted to the bypass port. The pre-setregulated flow is selected by energising the solenoid.The adjustable relief valve vents the spring chamber atthe pre-set pressure and diverts the flow to the bypassport. It may be necessary to fit a 10 bar check valve inthe bypass or regulated line to ensure the valveswitches fully.

Inlet flow passes through the adjustable orifice and theradial holes in the spool/sleeve assembly then out ofthe regulated port. The pressure drop across theorifice is sensed at each end of the spool, producing aforce which, at the required flow rate, overcomes thespring force. The resultant movement of the spool
regulates the flow by opening more radial holes to thebypass port. The solenoid valve vents the springchamber to a drain line and in its de-energised modeall inlet flow is diverted to the bypass port. The pre-setregulated flow is selected by energising the solenoid.The adjustable pilot valve vents the spring chamberwhen the regulated line reaches the preset pressure,diverting the flow to the bypass port where thepressure can continue to rise if necessary. It may benecessary to fit a 10 bar check valve in the bypass orregulated line to ensure the valve switches fully.

WATTAGE
VOLTAGES
C13 (for 13 mm tubes) = 14, 22 & 27 Watts
C16 (for 16 mm tubes) = 19 & 29 Watts
Standard 12 VDC 110 VRAC24 VDC 220 VRAC
Special/Optional Other Voltages are available on request
DUTY RATING
The coil is rated for continuous operation at nominal voltage+/- 10% and a ambient range of -20 to +40.
Note. Coil performance, force produced and powercomsumed, is effected by the heat of the coil,performance figures given in this catalogue aremeasured under simulated continuous duty conditionsat the coil stabilised temperature. It is important toverify the actual conditions the valve will experience forany given application it should be tested in situ toconfirm valve selection.
WIRE INSULATION
The coil winding is copper magnet wire insulationequivalent to class N (200°C).
ENCAPSULATION MATERIAL
C13, 14 Watt coils and C16, 19 Watt coils are black incolour and made from PBT (Black Polybutylene Rein-forced) equivalent to Class F (155°C)
C13, 22 & 27 Watt coils and C16, 29 Watt coils areblack in colour and made from IXEF (BlackPolyarylamide Reninforced) equivalent to Class H(180°C)
INGRESS PROTECTION (IP) BS EN 60529
The coil/tube joint is sealed by “O” rings preventing fluidingress and the possibility of tube corrosion.
Different electrical connectors offer different levels ofprotection the minimum being the DIN 43650 connectorwith a gasket at IP65. Integrated Hydraulics offer a widerange of connector types - details of which are availableon request.
CONNECTORS
H = ISO4400 Standard DIN43650 2 pin and earth
F = Black Flying Leads 1.5mm2
wire 600 mm long, 15 AWG, 2.2 mm diameter, Teflon FEP covered (DC voltage only)
DM = Deutsch Moulded 2 way DT04-2P series. (DC voltage only).
ALTERNATING CURRENT
For AC voltage an ISO4400 rectified connector mustbe used, as the coils are wound for DC.The correct connector is available from the factory:
110 VAC = AXP9997-115220 VAC = AXP9997-230
AC Voltage Connector Circuit Diagram
VDR is fitted for over-voltage protection.Diodes are rated at 1.5 amp.
Caution – When handling coils after or during use theymaybe hot which can cause burning to the skin. Handlewith care and use the appropriate equipment.

These unloader valves are used to unload a pump, orpumps, to tank when pressure in a separate part of thecircuit reaches a pre-set level. The valves will close,causing the circuit to reload, when the pressure dropsto approximately 85% of the unload pressure. The mostcommon application is to maintain a pressure in anaccumulator which may be used in an emergency tooperate an essential hydraulic function. (Eg, a brakecircuit). The 1PUL60 valve has a drain port to ensurecorrect valve function while allowing the bypassed oil tobe used for a secondary circuit requirement.
Inlet pressure is seen on the nose of the valve andsystem pressure (downstream of the system checkvalve) operates on the system pilot port. Whenpressure rises to the valve setting, the relief sectionopens and the system pressure acts on the pilot pistonto hold the valve in the open position. The ratio betweenthe pilot piston diameter and the seat diameter to therelief valve pilot section ensures that the valve will bemaintained in the fully open position until the systempressure drops to approximately 85% of the unloadpressure.
SPECIFICATIONS
OPERATION
Valves are available as cartridges for installation intospecial line bodies or into custom designed HydraulicIntegrated Circuits. (NOTE: Provision must be made fora system check valve and a pilot line to signal thesystem pressure). Valve assemblies can be suppliedcomplete in a line body for use in accumulator circuits.Bodied valves include a check valve and the requiredconnection from the system to the valve pilot port.

Two-pump unloader valves are used in systems with
combinations of two (or more) pumps to give high flowat low pressure and high pressure at low flow. Thevalves bypass the flow from the low pressure pump(s)to tank at a pre-set pressure. This allows pumpselection to give, for example, rapid advance and highpower compaction with the most economic usage of system components and energy requirements.
Pump inlet to P1 and P2 is combined to give maximumflow at low pressure. When the load pressureincreases to the valve setting the high flow (low
pressure) pump is bypassed from P1 to tank allowingnearly all system power to be used for the highpressure pump. (See graph for the pressure drop of the dumped flow). The system relief valve providesprotection by limiting the maximum pressure in thesystem line.
SPECIFICATIONS
This is a self contained system including two replaceable
cartridges with full adjustment through their respectiveranges. Hardened working components give long,trouble-free life and single body reduces plumbing to aminimum.

BALL TYPE
This valve provides a means of sensing the higher
pressures between two lines on a hydraulic circuitallowing this line to be used for an auxiliary functionsuch as the removal of a mechanically applied brake,the operation of a gauge or to give a remote pressuresensing line for the control of a separate valve.
When a higher pressure is sensed at inlet (1) than atinlet (3) the ball within the cartridge is forced against aseat opening the higher pressure to outlet (2). Whenthe higher pressure appears at inlet (3) the ball isforced against another seat which blocks inlet (1) andopens up inlet (3) to outlet (2).

This valve provides a means of interrupting a pressureline when a predetermined pilot pressure is reached ina normally open or normally closed form.
The valve can be used in any pilot or small flow system
as a remotely operated sequence valve.
When a pre-set pilot pressure is reached the spoolmoves back against the spring either opening orclosing the line between inlet and outlet. When the pilotpressure falls the valve will return to its normal position.

This valve provides hot oil exhaust in a closed loophydrostatic system. The high pressure line causes thevalve to open the low pressure line to tank through aback pressure relief valve, thus purging the system ofextra oil supplied by the charge pump.
Inlet (2) and inlet (4) are fed by the pressure lines of aclose loop hydraulic system. As soon as pressurerises in either line, the spool which is internally pilotedopens the lower pressure side to tank through a reliefvalve. This allows the charge pump flow to beexhausted to tank after the oil has done its work, hencethe title ‘hot oil shuttle’. If the system is reversed, thespool switches in the opposite direction, maintaininghot oil exhaust.

For use in conjunction with pilot valves to allow control oflarger flows. When used with a 2/2 solenoid valve thecombination allows control of flows to 80 lts/min (20 USgpm). With a pilot relief valve or a proportional reliefvalve the element becomes a high flow pilot style
pressure reducing valve. With a needle valve an on/offfunction is achieved.The outlet flow becomes the controlled pressure line. SPECIFICATIONS
APPLICATION
Very versatile in its application using hardened andground spool and sleeve giving minimal internalleakage and long life.High flow and pressure rating increases the variety ofapplications into which it can fit.With small modifications to the spool the valve can beused as a compensator for restrictive pressure com-pensated flow controls.

With a pilot valve fitted the valve will only close when flowis allowed across the orifice in the middle of the spool.Flow passing across this orifice will cause there to be apressure difference that acts over the full area of thespool to move it back against the spring that biases itopen. By controlling the pressure in the spring chamberyou can control the pressure at which the valve closes.

For use in conjunction with pilot valves to allow control of larger flows. When used with a 2/2 solenoid valve thecombination allows control of flows to 350 lts/min (95US gpm). With a pilot relief valve or a proportional relief valve the element becomes a high flow pilot style relief.
With a needle valve an on/off function is achieved.The outlet flow would normally go to tank because backpressure will act on the pilot cartridge to increase theswitching pressure.

For use in conjunction with pilot valves to allow control of
larger flows. When used with a 2/2 solenoid valve the
combination allows control of flows to 400 lts/min (100
US gpm). With a pilot relief valve or a proportional relief valve the element becomes a high flow pilot style
ventable relief. With a needle valve an on/off function isachieved.
The outlet flow would normally go to tank because back
pressure will act on the pilot cartridge to increase theswitching pressure.
SPECIFICATIONS
APPLICATION
Very versatile in its application using hardened and
ground spool and sleeve giving minimal internal
leakage and long life.
High flow and pressure rating increases the variety of applications into which it can fit.
With small modifications to the spool the valve can be
used in load sensing circuits or as a compensator for
by-pass pressure compensated flow controls.

Overcentre valves give static and dynamic control of loadsby regulating the flow into and out of hydraulic actuators.When installed close to or within an actuator, theovercentre valve will stop runaway in the event of hoseburst and if open centre directional control valves are used,will allow thermal expansion relief of the hydraulic fluid.
Single overcentre valves are normally used when the loadis unidirectional, for example an aerial platform or crane
and dual overcentre valves are used for controlling loadsin both directions for motor applications or for cylindersgoing over centre.
The 1CER series overcentre valve performs all duties of aregular overcentre but is able to relieve and stay openirrespective of downstream pressure. This enables thevalve to operate when used with a closed centre direc-tional valve which has service line reliefs. The poppet ispressure balanced, preventing relief setting increase dueto back pressure.--
In the 1CEB series pressure balanced overcentre reliefsetting is unaffected by back pressure, enabling the valve
to stay open when the valve port pressure rises. This willallow the control of regenerative or meter out proportionalsystems.

OPERATION
PILOT RATIOS
The check section allows free flow into the actuator thenholds and locks the load against movement. The pilotassisted relief valve section will give controlled movementwhen pliot pressure is applied. The relief section isnormally set to open at a pressure at least 1.3 times themaximum load induced pressure but the pressurerequired to open the valve and allow movement dependson the pilot ratio of the valve. For optimisation of load
control and energy usage, a choice of pilot ratios isavailable.
The pressure required to open the valve and start actuatormovement can be calculated as follows:
Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot Ratio

Pilot check valves allow flow to pass in one direction,with a low pressure drop, then prevent reverse flowuntil pilot pressure is applied. There are manyapplications for this valve type, the most commonbeing to lock and hold a cylinder, or another hydraulicactuator, in position.
The 4CK90 is a small cartridge valve and is ideallysuited for fitting directly into a cylinder, giving economy
of installation, direct control of cylinder movement andease of servicing.
FEATURES
Pressure on the valve port causes the poppet to liftagainst the spring force, allowing the flow to thecylinder port. Reverse flow is prevented by the poppetreseating. Pressure applied to the pilot port willovercome the cylinder port pressure and lift the poppetfrom its seat, allowing flow from the cylinder to valveport.

NOTE: Central locating dimple should always point towards the solenoid valve, ie, always away from the subplate.
Integrated Hydraulics have designed their range of CETOP Modular Stacking Valves to be used in conjunctionwith sealing plates which give maximum flexibility and versatility to the user. Each plate has a notch cut outwhich is used for correct mounting of each valve to give the required function on the correct port or in the right
direction. The CETOP 03 plate has a central dimple for locating the plate in the centre of the valve.

Overcentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directionalcontrol valves are used, will allow thermal expansionrelief of the hydraulic fluid.
The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.
Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directional for motorapplications or for cylinders going over centre.
The check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pliot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allowmovement depends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.
The pressure required to open the valve and startactuator movement can be calculated as follows:
Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot Ratio

INSTALLATION & MAINTENANCE
APPLICATION
Suitable for any application requiring manual generation ofhydraulic power, eg, emergency back up, operatinghydraulic cylinders or actuators, hydrostatic testing, etc.
MOUNTINGSuitable for manifold mounting into Integrated Hydraulics’cavity type AXP878 (2 port, 7/8”-14 UNF thread). Thepump body is screwed into the cavity; the handlemechanism rotates on the body to allow alignment asrequired for application.
Mounting orientation is universal.
Sealing is by nitrile rubber ‘O’ rings (standard material;other materials such as fluorocarbon or ethylenepropylene are available to order).
Recommended tightening torque when fitting pump bodyinto manifold: 45-50 Nm.
CONNECTIONS
Inlet in base; outlet in side, to suit specified cavitydimensions. As with any hand pump, the inlet line back totank should be kept as short and unconstricted aspossible for optimum performance.
COMMISSIONING
The pump should be operated during installation to leaktest and bleed the hydraulic circuit. Failure to do so willresult in reduced pump displacement and a spongeyaction.
MAINTENANCE
The inlet strainer is easily accessible for cleaning on thebase of the pump. Should it be necessary, inlet and outletnon return valves are also accessible for cleaning.Rubber seal components are easily replaceable usingstandard tools; service kits are available.

Our cavities have been designed to achieve standardisation based on each thread size to reduce the amount oftooling required to cover the valve range. All new designs of cartridge are made to fit the ISO recommendationsfor standard cavities. The diagram below shows the sequence of tooling using tools specified in the followingpages. Note: a pilot drill may be required before the form drill.
Great care must be taken to ensure that the tools are inserted along the same machining axis to maintaincorrect concentricities, hence bodies should not be moved between operations.
