Model Description/Performance Characteristics
General DescriptionDG3V-8 models are single stage remotepilot operated directional control valves.These valves are generally used tocontrol the direction of flow in a hydrauliccircuit. This in turn would control themovement of a work cylinder or therotation of a fluid motor.
Installation Data
Drain connection must be piped directlyto tank through a surge free line so therewill be no back pressure at this port.
Pressure Centered Models
Designated by ‘‘D’’ under spring/spoolarrangement in model code.
This option provides faster, morepositive spring centering time by use ofpilot pressure to center the spool. Thevalve spool is returned to center positionwhen pilot pressure is applied at bothends of the spool. The centering springsare used in addition to pilot pressure toensure positive centering of spool.
If pilot pressure fails or falls below therequired minimum, the spool will springreturn to the center position. Pilotpressure is not available through theuse of and integral check valve.Pressure centered valves have a drainport ‘‘W’’ and subplate must haveprovisions for this feature.
NotePressure centered valves require apilot valve which directs pilot oil toconnections ‘‘X’’ and ‘‘Y’’ of the valveat the same time pressure centeringis desired. The centering timedepends on the rate of pressure risein the pilot chamber.
Spring Offset Models
Designated by ‘‘A’’ under spring/spoolarrangement in model code.
Spring offset model has an internalspring which returns the spool to offsetposition when the pilot connection ‘‘X’’ isopen to tank. Pilot connection ‘‘Y’’becomes a drain connection and mustbe pioped directly to tank at atmosphericpressure through a surge-free tank line.Back pressure at this connection wouldcause valve to malfunction.
Caution: Spring offsetmodels contain a highassembled spring load.
Call Vickers Service for disassemblyinstructions.
Spring Centered Models
Designated by ‘‘C’’ under spring/spoolarrangement in model code.
A spring and washer arrangement isused on both ends of the spool. Ifcontrol pressure is removed, the valvewill go to center position due to springforce.
No-Spring Models
Designated by a ‘‘Blank’’ underspring/spool arrangement in model code.
When pilot pressure is removed onno-spring models, the spool remains inthe last position attained provided thereis no unusual shock, vibration, pressuretransients and the spool axis is horizontal.
Performance CharacteristicsSpring centered, pressure centered andspring offset models require continuouspilot pressure to maintain shifted position.Spring centered models return valvespool to center position by centeringsprings when pilot pressure fails or fallsbelow minimum requirement.
Port connections are made by mountingthe valves on a subplate or manifoldhaving mounting dimensions whichconform to NFPA-D08/D10(ISO-4401-08/10) pattern.
Shift Times
Shift times are defined as the time frompilot pressure application/removal to thepoint of the start of a pressurerise/decline in appropriate port.
Caution: Flow conditionsof the spring centeredposition must be selected
with care, both for the effect on thedirection of the flow, and the pilotpressure. (The “9” main spool willnot ensure sufficient pilot pressure inthe center position for internal pilotpressure models.)
Pressure centered models: Valvespool is returned to center positionby pilot pressure, when pilotpressure is removed. If pilotpressure fails or falls below therequired minimum, the valve spoolwill spring return to center position.(At spring centered valve flow rates).
Caution: Surges of oil in acommon pilot valve drainline serving these and other
valves can be of sufficient magnitudeto cause inadvertant shifting of thesevalves. This is particularly critical inthe no-spring type valves. Separatedrain lines or a vented drain manifoldwith a continuous downward path totank is necessary. This applies toconnection ‘‘Y’’ on spring offset valveswhere ‘‘Y’’ is piped as a drain forpressure centered models. Drainconnection ‘‘W’’ must be piped directlyto tank through a surge free line sothere will be no back pressure atdrain.
NoteAny sliding spool valve, if held forlong periods of time, may stickand not spring return due to fluidresidue formation and therefore,should be cycled periodically toprevent this from happening.
If used as other than a normal 4–wayvalve, consult your Vickers representative.

Optional Features
Integral Check Valves
For internal pilot pressure, an integralpressure port check valve is available.This back pressure will be present atthe cylinder ports. The pilot pressuregenerated is the total of: P→T dropthrough the valve in center condition,pressure drop through the checkvalve, plus the pressure at the tankport.
To prevent load drop, a check valvein the pressure port can be used toprevent reverse flow from a cylinderport to the pressure port.
Pilot ChokeDGMFN-3-Y-A2W-B2W-41
Pilot choke increases the amount oftime to shift the mainstage spool,lowering the possibility of large flowtransients in the circuit. It is adjusted bybacking off locknuts and turningadjusting screws inward to decreaserate of spool travel and outward toincrease spool travel rate. See spoolcontrol modifications in model code.
Stroke Adjustment
Stroke adjustment limits movement ofthe mainstage spool. Backing off thejamnut and turning the adjusting screwinward decreases spool stroke. Seespool control modifications in modelcode.

Model Description/Performance Characteristics
Model DescriptionDG5V-8 models are two-stage directionalcontrol valves having an integrallymounted wet armature solenoid pilotvalve. These valves are generally usedto control the movement of a workcylinder or the rotation of a fluid motor.
Pressure Centered Models
Designated by ‘‘D’’ under spring/spoolarrangement in model code.
This option provides faster, morepositive spring centering time by use ofpilot pressure to center the spool. Thevalve spool is returned to center positionwhen pilot pressure is applied at bothends of the spool. The centering springsare used in addition to pilot pressure toensure positive centering of spool.
If pilot pressure fails or falls below therequired minimum, the spool will springreturn to the center position. Pilotpressure is not available through the useof and integral check valve. Pressurecentered valves have a drain port ‘‘W’’and must have provisions for this feature.
NotePressure centered valves require apilot valve which directs pilot oil toconnections ‘‘A’’ and ‘‘B’’ of the valveat the same time pressure centeringis desired. The centering timedepends on the rate of pressure risein the pilot chamber.
Spring Offset ModelsDesignated by ‘‘A’’ under spring/spoolarrangement in model code.
Spring offset model has an internalspring which offsets the spool when pilotconnection ‘‘X’’ is vented to tank. Whenpressure is removed, the spring is usedto return the spool to an offset position.
Caution: Spring offset modelscontain a high assembledspring load. Call Vickers
Service for disassembly instructions.
Spring Centered Models
Designated by ‘‘C’’ under spring/spoolarrangement in model code.
A spring and washer arrangement isused on both ends of the spool. If controlpressure is removed, the valve will go tocenter position due to spring force.
No-Spring Models
Designated by a ‘‘Blank’’ underspring/spool arrangement in model code.
When the solenoid is de-energized, thespool returns to the last position attained.
Performance CharacteristicsSpring centered, pressure centered andspring offset models require continuouspilot pressure to maintain shiftedposition. Centering springs on springcentered and pressure centered modelsreturn the valve spool to the centerposition pilot pressure fails or falls belowminimum requirement.
Shift Times
Shift times are defined as the time fromsolenoid energization/de-energization tothe point of the start of a pressurerise/decline in appropriate port.
Caution: Flow conditionsof the spring centeredposition must be selected
with care, both for the effect on thedirection of the flow, and the pilotpressure. (The “9” main spool willnot ensure sufficient pilot pressure inthe center position.)
Pressure centered models: Valvespool is returned to center positionby pilot pressure, when pilot pressureis removed. If pilot pressure fails orfalls below the required minimum,the valve spool will spring return tocenter position. (At spring centeredvalve flow rates).
Caution: Surges of oil in acommon tank line servingthese and other valves
can be sufficient enough to causeinadvertent shifting of these valves.This is very critical in the no-springdetented valves. Separate tank linesor a vented manifold with a continuousdownward path to tank is necessary.
NoteAny sliding spool valve, if held forlong periods of time, may stickand not spring return due to fluidresidue formation and therefore,should be cycled periodically toprevent this from happening.
Shifting Action
The pilot valve solenoids of springcentered, pressure centered, and springoffset models must be energizedcontinuously to keep the main stagespool in the shifted position. No-springdetented models only need to beenergized momentarily (forapproximately 0.1 second).
Spring centered and pressure centeredmodels return the valve spool to thecenter position when both solenoids arede-energized or pilot pressure fails orfalls below minimum requirements.Spring offset models return the spool tothe offset position by pilot pressurewhen the solenoid is de-energized.
When no-spring detented models arede-energized, the pilot and main spoolsremain in their last position as long asthere are no unusual shock, vibration, orpressure transients, and the spool axisis horizontal. If pilot pressure fails orfalls below minimum requirements, themain spool will spring center (at springcentered flow rates), but will not drift to areversal of flow position. The pilot stagewill remain in the detented position.
When used as other than a normal4–way valve, consult your Vickersrepresentative.

� The method for verifying the rated fatigue pressure of the complete unit conforms to NFPA/T2.6.1 R1-1991 (Catalog C/90), Fluid Power Systems and Products method for verifying the fatigue pressure rating of the pressure containing envelope.� Internal drain models drain the pilot valve through the tank port of the mainstage. External drain models drain the pilot valve through the
‘‘Y’ port of the mainstage. To provide proper operation without malfunction, the pilot pressure must always exceed tank or drain line pressure by the minimum pilot pressure required per valve and spool type (see charts on page 16). Tank or drain line surges which would reduce this differential are to be avoided as they may cause the mainstage to shift. Mainstage tank pressure is limited to the tank line rating of the pilot valve on internally drained models (with ‘‘T’’ included in the model code). Internal drains may be used with all models except pressure centered ‘‘D’’ models. Pressure centered models must be externally drained through ‘‘Y’’ and ‘‘W’’ ports. To achieve the maximum tank line rating of 350 bar (5000 psi) of the mainstage, an external pilot drain must be used and it is recommended that a separate line be provided directly to the tank.

Response Times
Response times are defined as the timefrom solenoid energization/de-energizationto the point of the start of a pressurerise/decline in appropriate port.
Solenoid Energizing
Spring centered, pressure centered andspring offset DG5V-8 types must beenergized continuously. No-springdetented DG5V-8 type may beenergized momentarily. Pressurecentered and spring centered DG5V-8types return valve spool to centerposition when both solenoids arede-energized.
Mounting Position
No–spring detented valves must beinstalled with the longitudinal axishorizontal for good machine reliability.The mounting position of springcentered and spring offset models isunrestricted provided that the pilotpressure supply is maintained asrequired. (Spring offset valves do nothave a spring in the main spool section.)

Optional Features
Pilot ChokeDGMFN-3-Y-A2W-B2W-41
Pilot choke increases the amount of timeto shift the mainstage spool, loweringthe possibility of large flow transients inthe circuit. It is adjusted by backing offlocknuts and turning adjusting screwsinward to decrease rate of spool traveland outward to increase spool travelrate. See spool control modifications inmodel code.
Stroke Adjustment
Stroke adjustment limits movement ofthe mainstage spool. Backing off thejamnut and turning the adjusting screwinward decreases spool stroke. Seespool control modifications in modelcode.
Reducer ModuleDGMX2-3-PP-FW-S-40-EN91
The reducer module is required forpiloted models when pilot prerssureexceeds 210 bar (3000 psi). Thesetwo-stage spool valves maintain areduced outlet pressure againstvariations in inlet pressure. Thesevalves are able to act as relief valves (at50% of the maximum flow) to preventexcess pressure being developed whenan actuator is subject to a reactive load.
Pressure Centered Models
This option provides faster springcentering time by using pilot pressure tocenter the spool. The centering springsare used in addition to pilot pressure toensure positive centering of the spool.The valve spool is returned to centerposition by pilot pressure and centeringsprings. If pilot pressure fails or fallsbelow the required minimum, the spoolwill return to center position at minimumpilot pressure flow rates for pressurecentered valves.

Integral Check Valves
For internal pilot pressure, an integralpressure port check valve is requiredfor internally piloted valves with opencenter spools (0,1,4,8 & 9). The pilotpressure generated is the total of:P→T drop through the valve in centercondition, pressure drop through thecheck valve, plus the pressure at thetank port.
For proper operation, total pressuredrop must be greater than theminimum required pilot pressure (seechart). To prevent load drop, a checkvalve in the pressure port can beused to prevent reverse flow from acylinder port to pressure port. If usingas reverse flow check, maximumreverse pressure is limited to 210 bar(3000 psi).
X - Fast Response
Use of this option decreases the shifttime and increases the system shockgeneration. This requires the removal ofan orifice plug within the mainstagebody. It is available on all models byadding ‘‘X’’ to the model code. Example:DG5V-8-(*)-2C-X-(*)-10
When a standard performancepilot is selected and pilotpressure is above 3000 psi,
the reducer module is required to limithigh drain line pressure transientsgenerated during shifting.

Surge Suppression Devices(For DC Valves)
Connector can be positioned at 90�intervals on valve by re-assemblingcontact holder into appropriateposition inside connector housing.
Use U12 or U11 type connectors with12 and 24V DC coils if rectification isrequired.
Connectors with and without indicatorlights are available (order separately):
Standard diodeDiode in parallel with coil. When switch(S1) is opened, the energy stored in thecoil is trapped and dissipated by thediode (D1).
D Works only with DC voltage
D Polarity dependent
D Increases drop out time
TranszorbDiode and Zener diode in parallel withcoil. When switch (S1) is opened, theenergy stored in the coil is trapped anddissipated by the diode (D1) and Zenerdiode (Z1) and the coil resistance.
D The Zener makes exact limitation ofinductive spikes.

Application DataFluid Cleanliness
Proper fluid condition is essential forlong and satisfactory life of hydrauliccomponents and systems. Hydraulicfluid must have the correct balance ofcleanliness, materials, and additives forprotection against wear of components,elevated viscosity, and inclusion of air.
Essential information on the correctmethods for treating hydraulic fluid isincluded in Vickers publication 561“Vickers Guide to SystemicContamination Control” available fromyour local Vickers distributor or bycontacting Vickers, Incorporated.Recommendations on filtration and theselection of products to control fluidcondition are included in 561.
Recommended cleanliness levels, usingpetroleum oil under common conditions,are based on the highest fluid pressurelevels in the system and are coded in the
chart below. Fluids other than petroleum,severe service cycles, or temperatureextremes are cause for adjustment ofthese cleanliness codes.
Vickers products, as any components,will operate with apparent satisfaction influids with higher cleanliness codes thanthose described. Other manufacturerswill often recommend levels above thosespecified. Experience has shown,however, that life of any hydrauliccomponent is shortened in fluids withhigher cleanliness codes than thoselisted below. These codes have beenproven to provide a long, trouble-freeservice life for the products shown,regardless of the manufacturer.
Fluids and Seals
The use of synthetic, fire resistant fluidsrequires a valve with special seals. Addprefix ‘‘F3’’ to the model code when
phosphate ester oil or its blend are to beused. Add prefix ‘‘F6’’ to the model codewhen water glycol or water-in-oilemulsions are to be used.
The pilot valve has ‘‘F3’’ seals (Viton�) asstandard. All internal seals of themainstage are also ‘‘F3’’. Mounting faceseals are standard (Buna-N). ‘‘F6’’ prefixdenotes special seals (Nitrile) throughoutthe valve assembly.
