Parker reserves the right to modify products without prior notice.Typical curves and diagrams are used in this catalog.Even though the catalog is revised and updated continuously,there is always the possibility of errors. For more detailed infor-

mation about the products, please contact Parker.

This catalog has been designed to give a br ief overview ofK170LS valves, and to make it easy for you to study and choosefrom the different options available, so that we may customizeyour valve in accordance with your wishes. In addition to general

information and basic technical data, the catalog therefore con-tains descriptions of the options available for various so-calledfunction areas of the valve.

Each function area is given as a subheading, followed by abrief description. When options are available for a function area,the subheading is followed by an Item number in brackets, e.g.Pressure relief valve [16]. This is followed by a series of coded

options, e.g. PA1, Y1,together with a brief description of whateach code represents. Alternatively, one or more pressure, flowor voltage options are given.

On page 7 is a general circuit diagram showing the basic

function areas in a K170LS valve and the item numbers that rep-resent them. Naturally, the same item numbers are used for therespective function areas in all sub-circuit diagrams that appearelsewhere in the catalog. Please note that, unless stated other-wise, all sections and views of the valves have been drawn asseen from the inlet section.

The K170LS directional control valve can be easily specified us-ing Parker computer programme. This means the customer canoptimize his valve specification to give the best performance forhis application and specific hydraulic system.

Once the demands placed on each individual function havebeen specified the computer will select the valve design requiredto give optimum performance. The computer also produces com-plete documentation for your valve, in the form of a detailedspecification and hydraulic circuit diagram.

The computer also generates a unique identification number foreach valve type and customer. The number is then stamped intothe I.D. plate of each valve. The specification of your valve isthen recorded by Parker, so that exact identification of the prod-uct can be made at any time in the future to facilitate repeat or-dering or servicing.

Our experienced engineers have in-depth knowledge of thedifferent types of hydraulic system and the ways in which theywork. They are at your disposal to offer qualified advice on thebest system for the desired combination of functions, control

Inlet section[12-29]The inlet section is equipped with pump (P1) and tank connec-tions (T1, T2), a connection for the load signal to LS pumps(LS), a connection for pilot pressure supply for external use(PS), a gauge point for pump (PX) and load signal pressures(PL). In the basic variant, the pump connection P1 [26] and tank

connection T1 [25] are open, while the other connections areplugged.

Functions such as maximum pressure relief, copying of theload signal, pressure reduction for internal pilot-supply, as wellas a pilot filter and counterpressure valves can also be integrat-ed into the section.

Internal pilot pressure supply [12]

R Pressure reducer for pilot supply.Internal pilot pressure supply is a valve function, builtinto the inlet section, which works as both a pressure

reducer and a pressure relief valve in the pilot circuit.For safety reasons, the R-cartridge has also beenequipped with a separate safety valve function that pre-vents the maximum permissible reduced pressure frombeing exceeded. A check valve prevents pilot oil fromleaking back to the pump, and therefore enables thepressure in the pilot supply circuit to be maintained inthe event of a temporary fall in pump pressure, e.g. dur-ing a rapid lowering movement, to secure pilot supplyduring pump pressure drop, we recomend to connectan accumulator to the PS port.Pilot pressure for external use, e.g. for delivery to PCL4hydraulic remote control valves, can be tapped from thePS connection on the inlet section.

RX Without pressure reducer for pilot supply.

Pilot pressure [13]

The pilot supply pressure can be set at either 35 or 45 bar.

Pilot filter [14]

S Built in strainer for the pilot supply.Coarse strainer with bypass function in the internal pilotpressure supply. The strainer protects the pilot circuitfrom dirt, especially during start-up of the system.

YS Adapter for connection of external filter for pilot pres-sure oil. Enables the pilot circuit to be supplied withcleaner oil compared with the rest of the system.See also filtration, page 6. Internal pilot-pressure

Load signal system

The load signal system consists of a number of shuttle valves,which compare the load signals from different spool sectionsand send the highest signal to the connection PL, or to a copy-ing spool in the inlet section.The system permits a certain consumption in the load signal lineto the pump, without the load signal level being affected. Thisenables simpler system design, with the possibility of installinglogic systems in the LS circuit. Thanks to drainage in the pumpLS regulator, the system gives better winter operating character-istics with faster response, since the oil in the LS circuit is al-ways warm. In addition to this, the system prevents disruptivemicro-sinking of the load in the beginning of the lifting phase.

Inlet section type [15]

The inlet section is available in two variants, one for CP systemsand one for systems with LS pumps.

LS Inlet section for systems with LS pump.The system is equipped with a directly controlled pres-sure relief valve, PA1[16], which protects the pump and

inlet side of the valve. The LS is always equipped with aload-signal copy function.

CP Inlet section for constant pressure systems.Same as LS but without load-signal copy function, LS.

A025 Inlet section for un-loading constant pressure systems(CPU).

Pressure relief valve [16]

The inlet section is normally equipped with a pressure reliefvalve to protect the pump and valve from pressure peaks in thesystem.

PA1 Direct acting port relief valve, PLC183, with very fast

opening sequence and good pressure characteristics.The replaceable PLC cartridge is factory set. The car-tridge has a make-up function, which means that oil isable to flow from the tank gallery to the pump gallery inthe event of underpressure in the pump circuit. For set-ting values, please see Pressure settings [17].

Y1 Without relief valve.Plug which can replace the pressure relief valve. TheY1-plug blocks the connection between the pump andtank completely. Pressure relief valve PA1

Pressure setting [17]

Pressure setting for PA1 [16]

The PA1 direct acting pressure relief valve is deliveredwith a fixed setting. The standard settings (in bar) avail-able are as follows:

Setting pressure in bar: 50, 63, 80, 100, 125, 140, 160,175, 190, 210, 230, 240, 250, 260, 280, 300 and 330.

The settings 280, 300 and 330 bar are only applicableto valves of nodular-iron.

PA1 needs to be set 20 bar above pump pressure.

See also technical data, page 6.

Tank connection T2 [24]

T2B Alternative tank connection T2 plugged. Commonvariant.

T2 Alternative tank connection T2 open.

Counterpressure valve

The counterpressure valve, which raises the pressure in thevalves tank gallery, is placed in the inlet section. It is available intwo versions: MF with fixed setting and MP with pilot-controlledsetting.

By raising the counterpressure, the anti-cavitation character-istics of the K170LS are improved still further. This might, for ex-ample, be desirable in situations where make-up flow is directedinto the large side of the cylinder during the lowering of loads.Good make-up characteristics eliminate the risk of cavitationand reduce the risk of damage to the cylinder seals. They arealso important for functions in which a lowering movementchanges to a lifting movement without a time delay.

The pilot-operated version gives counterpressure only when

it receives a signal. It can be employed in such a way that thesignal to the counterpressure valve is connected only to thespool-actuator signal(s) controlling the lowering movement(s)that need extra counterpressure. In this way, unnecessary loss-es can be avoided.

MF Counterpressure valve factory set to give 5 bar counter-pressure at a flow of 20 l/min.

MP Pilot operated counterpressure valve for external con-trol of counterpressure between 0 and 36 bar. Tankconnection T1 [25] must be open and tank connectionT3 must be plugged (T3B [34]).The MP pilot operated variant only gives a counter-pressure upon receipt of signal. This can be exploitedso that the signal to the counterpressure valve is con-nected only to the spool actuating signal(s) controllingthe lowering movement(s) that need an extra counter-pressure, thus avoiding unnecessary losses. Max per-mitted signal pressure is 30 bar. The relationship be-tween pressure and signal is 1.2:1.

In the case of parallel connected valves, the PL connection loadsensing signal in the last valve passes to the LSP connection inthe first valve. The rear valve can be fed with pump oil, by con-necting P2 and P1.

End section[30 - 44]The end section is available in two variants, one with all connec-tions machined and one without machined connections for pump(P2), and tank (T3).

In the basic variant, the LS connection LSP [31], pump con-nection P2 [32] and tank connection T3 [34] are plugged.

In addition to the two standard models, there is a specialadapter plate (AP) which is used when the valve flanges against

an L90LS valve. The adapter plate contains only the pilot tank

connection and through channels which connect the pump, tankpilot pump, pilot tank and LS channels of the K170LS and L90LSvalves, respectively. Thus, the pump and tank need only be con-nected to the K170LS valve.

The valves are turned so that the adapter plate serves as acommon end plate for the K170LS and L90LS.


End Section

Separate tank connection for the pilot circuit[40]

TP Separate tank connection for the pilot circuit is open.The connection to the main tank gallery of the direc-tional valve is blocked in the inlet section. The functionis recomended for systems in which there is a risk ofdynamic pressure fluctuations in the tank line, whichcause fluctuations in the pilot circuit when there is acommon tank line.

NB! TP connection can not be plugged./ Not prepared for separate pilot return.

*The breakaway pressure is the pressure needed for the direc-tional valve to open the connection pump to service port. Thefinal pressure is the lowest pressure needed to effect full actua-tion of a spool in the directional valve. This data must be takeninto consideration when choosing control units, since the open-ing pressure of the control unit must be lower than the breaka-way pressure of the spool actuator in order to avoid jerky start-ing and stopping. However, the control units final pressure mustbe higher than the final pressure of the directional valve in orderto ensure that the spools can be fully actuated.

Spool selection[60-74]Spool options

The spool is the most important link between the operators acti-vation of a lever unit and the movement of the controlled func-tion. For this reason, Parker makes a wide range of standard

spools to meet many different function-specific demands. Spoolselection is effected with the aid of a computerized specificationprogram, using a series of different parameters to determine theoptimum spool for the job.

Spool function [60]

There are many spool variants which are adapted for differentflows, load conditions and actuator area ratios. The spools arealso available with different degrees of force feedback from theservice ports A and/or B.

D Double-acting spool for, e.g. double-acting cylinders.Blocked in the neutral position.

Dm Double-acting spool with drainage of service ports Aand B to tank, which prevents pressure build up in theneutral position. The spool is used as a double spool incombination with a double over-centre valve.

Da Double-acting spool with drainage of service port A totank, which prevents pressure build up in service port Ain the neutral position.

Db Double-acting spool with drainage of service port B totank, which prevents pressure build up in service port Bin the neutral position.

EA Single-action spool for, e.g. single-acting cylinder.Blocked in neutral position. Service port B blocked.

EA3 Single-acting spool for, e.g. single-acting cylinders.Blocked in neutral position. Service port B blocked dur-ing lifting function. Lowering function at both serviceports A and B.

EB Single-acting spool for, e.g. single-acting cylinders.Blocked in neutral position. Service port A blocked.

M Double-acting spool for, e.g. hydraulic motors. Floatingfunction in neutral position.

MA Double-acting spool for, e.g. hydraulic motors. Floatingfunction in neutral position, service port A to Tank.

MB Double-acting spool for, e.g. hydraulic motors. Floatingfunction in neutral position, service port B to Tank.

CB Regenerative spool for rapid feeding of cylinder viaservice port B. The large side of the cylinder is connect-ed to service port B.

Flow requirement [61 A,B]

The K170LS directional valve has a range of optimized spooldesigns for nominal flows up to 170 l/min when the section isequipped with an individual pressure compensator, K1 [66]. SeePressure compensator and/or load-hold check valve [66] forflow with other compensators.

Without an individual pressure compensator, flows up to 220l/min are obtainable, depending on the pre-set regulating differ-ence in the LS pump.

The desired flow to the service ports A and B is entered inthe ordering documentation. Parkers computerized specificationsystem then selects spools to give at least the flow required,also taking other parameters into account.

The maximum flow is then set by limiting the spool stroke bymeans of adjustment screws on the spool actuator or, in thecase of electro-hydraulic remote control, by setting the maximumcurrent.

See Flow settings [72] for details on factory setting of maxi-mum flow.

Area relationship [62]

The area relationship for a section is calculated by dividing thecylinder area that is connected to the service port B by the areathat is connected to the service port A. When the larger side ofthe cylinder is connected to the service port A, the relationshipis less than 1. The area relationship for a motor is 1.

Flow rate in % Optional force feedback

Load characteristics [63]

The character of the load can be selected according to five typi-cal cases. This information is entered so that the spool can begiven the best possible adaptation to the intended application.

LAB Lift load can change between service ports A and B.LA Lift load normally on service port A only.

LB Lift load normally on service port B only.

LN No or low lift load on service por ts A and B.

S Slewing function.

Force feedback [64 A,B]

The K170LS is available with a force-feedback option, which en-ables the positive sense of force control from CFO systems tobe transmitted to LS systems, thus enabling force-control char-acteristics to be incorporated in individual valve sections. Withforce control, the operator is better able to sense the increase inmachine load when a hard obstacle is met, e.g. in digging opera-tions.Force feed-back also gives a kind of ramp function, which re-sults in more gentle transitions during speed changes. This inturn has a stabilizing effect on the hydraulic system, and the ma-chine operating characteristics become smoother. Both these

characteristics are important, especially for slewing functionsand similar movements. With force feedback, machine wear isreduced and efficiency increases.The section can be equipped with force feedback for the serviceports A and B individually. The degree of force feedback can bechosen from three levels. The higher the level of force feedback,the greater the reduction in the functions speed upon increasingresistance for the same lever stroke. It follows from this that thelever must be moved further in order for the speed to remain thesame when the load is increasing.

Pressure compensators

The primary purpose of pressure compensation is to maintain aconstant flow rate to a function, regardless of pressure varia-

tions in the system. The facility is of special value in lifting func-tions.

Excellent simultaneous operation characteristicsIn cases where several machine functions are operated simulta-neously, the spool sections in the K170LS can be equipped withindividual, integrated pressure compensators. Subject to availa-ble pump capacity, sections so equipped will deliver the pre-de-termined constant flow regardless of other simultaneously oper-ated functions, and regardless of variations in load or feed pres-sure. Parker integrated pressure compensators have a veryquick response time and incorporate built-in load-hold checkvalves.

Increased or reduced function speed where required

To meet demands for exact speed in certain functions, Parkerintegrated pressure compensators comes in a number of fixedvariants that give flow rates from nominal to +55% through theselfsame spool (see K1 to KN1 below). To accommodate chang-ing operating conditions, a variant that can be adjusted on site togive 20% of nominal flow is also available (see KS below).

K1 Fixed pressure compensator with load-hold checkvalve. The spool gives nominal flow.

K2 Fixed pressure compensator with load-hold checkvalve. The spool gives 20% more than nominal flow.

K3 Fixed pressure compensator with load-hold checkvalve. The spool gives 55% more than nominal flow.N.B. Pump must deliver a pressure of at least p=30

bar. (30 bar above load signal reported to pump regula-tor.)

KN1 Fixed pressure compensator with extra fast load-holdcheck valve. The spool gives 15% more than nominalflow.

KS Adjustable pressure compensator with load-hold checkvalve. The spool gives 20% of nominal flow.

N1 Load-hold check valve.

Spool designation [69]

The task of spool selection can be submitted to Parkers com-puterized specification program, which adapts the spool tomatch the specific demands of each function, thus optimizingthe spool.

The information given at positions 61, 62, 63, 64 and 66therefore makes up part of the basis for the choice of spool.

Flow settings [72]

With PC and PCH spool actuators, flow limitation over the spoolto motor ports A and B can be effected by means of mechanicallimitation of the spool stroke length.

Qset When the spool section is equipped with a PC or PCHspool actuator, it can be delivered with a factory-setmaximum flow rate. Setting is carried out according tothe stated flow requirements to the A-and B-ports[61 A, B].

Qset A When the spool section is equipped with a PC or PCHspool actuator, it can be delivered with a factory-setmaximum flow rate. Setting is carried out according tothe stated flow requirements to the A-ports [61 A].

Qset B When the spool section is equipped with a PC or PCHspool actuator, it can be delivered with a factory-setmaximum flow rate. Setting is carried out according to

the stated flow requirements to the B-ports [61B].

When setting the flow rates for sections without pressure com-pensators in systems with LS pumps, the flow setting is madewith a p of 18 bar between the pump pressure in PX and theload signal in PL, at full flow take-up. For details on setting theflow for PC spool actuators, see page 13.

Feed reduction valves [75]

Any section in the K170LS valve can be equipped with individu-al feed reducing valves for the service ports A and B. These areused for those functions in the system which require a lowermaximum pressure than the normal operating pressure of thesystem. The reducing valve is infinitely adjustable between 30and 300 bar. It serves to reduce the pump pressure so that the

feed pressure in the section in which it is fitted does not exceedthe pre-set value.

The use of feed reducing valves enables the pressure to belimited without using any more than a pilot flow (

Port relief and/or anti-cavitation valves [76 A,B]

A specially designed cartridge valve is used as a port relief andanti-cavitation valve, PA, in the service ports. Its function is toprotect the valve and consumer from pressure peaks and exces-sive pressure in the system. The very rapid opening sequenceand good pressure characteristics make the cartridge valve anexcellent port relief valve. The anti-cavitation valve causes oil toflow from the tank gallery to the service port side in the event ofunderpressure in the service ports.

Separate anti-cavitation valve in service ports

As an alternative to the port relief valve, the service ports can befitted with anti-cavitation valves, N2 cartridges. These enable oilto flow from the tank gallery to the service port side in the eventof underpressure.The connection between tank and service port can also beblocked using an Y2-plug.
