Direct-controlled, dampened poppet valve with adjust-able spring loading. Three pressure stages withselectable maximum adjustment pressures of 64, 160,and 315 bar are available.

FunctionIf the fluid pressure exceeds the value adjusted on thepressure spring, then a connection via the valve poppetis enabled from P → T or A → B.

The integrated damping spool prevents pressure fluc-tuations in the transition region. The pressure setting isset using a adjusting screw, which is locked with a clamp-ing screw. The setting can be secured by means of acylinder lock if required.

Characteristics

The pilot operated pressure relief valves series DSDUlimit the system pressure by opening the pressure port tothe tank. Valves of this design series have a flat p/Q curve.They are mostly used for accumulator pressure relief. Inthis case the valve is set and sealed by TÜV (GermanTechnical Monitoring Association). The valve deliveryincludes a copy of the TÜV certificate.

Features• TÜV certificate

Function

The pressure reducing valve VM is a direct controlled,spring loaded 3 way pressure reducing valve, that is openin the neutral position. The valve closes the connectionfrom P to A (NG06) or B to A (NG10) when the pre-setpressure is exceeded.

If the pressure increases due to an externaly influencein connection A the spool moves and opens the connec-tion from A to T (NG06) or A to Y (NG10) until the pre-setpressure has been reached.

Technical data

Characteristics

DWK series with bypass check valve.

Series DWL

Pressure reducing valves of the DWL/DWK series main-tain a constant pressure on the secondary side (port A)at a set value.

To achieve accurate response the valve is fitted with asliding spool. A flow control valve is located in the spoolto maintain a constant pilot flow.

Characteristic curve

The drawings only show the adjustment type code 5 =turning knob with ratchet.

Graphic display and functionThe symbol shown in the characteristics corresponds tothe DIN/ISO representation for pressure reducing valveswith open neutral position, i.e. the valve goes into thecontrol setting only when the set secondary pressure isreached. The Parker valves of the series DWL and DWKare, in contrast, closed in the neutral position. The ad-vantage here is that the secondary build-up pressure isachieved more softly. Pressure peaks or pressure wavesdo not reach the actuator.

If the pressure on the secondary side A increases abovethe set pressure on the valve, the excess oil is directedthrough the pilot valve to reduce pressure. The pilot oilflow is directed to tank via port Y.

* The nominal flow volume is a recommended value for projecting,and is not the application limit for the valve which is dependent onthe individual permitted pressure increase value.

Pilot-Operated Proportional Pressure ValvesSeries VMY*L06N

VMY*06

The valve consists of the main stage with valve spoolsand the pilot stage with the proportional solenoids. Thedesired pressure can be variably set corresponding tothe command signal specified on the amplifier. The pro-portional solenoid converts the current of the amplifierinto force on the valve poppet of the pilot stage.

In the pilot stage, there is a flow limiter which suppliesthe pilot valve with pressure-independent pilot oil flowfrom the pressure port P. The pilot oil is returned via theY connection on the pilot valve to the tank.

The proportional pressure reducing valves of the seriesVMY*L*N allow the variable adjustment of the reducedpressure from 0 bar up to pmax. Typical applications arepressure systems, test equipment, or counterweight sys-tems. The electrical control of the valve takes place us-ing the digital amplifier module PCD00A-400. Use inclosed pressure control circuits is also possible. The valveis distinguished by its constancy.

FunctionWith the proportional solenoids de-energised a springforces the main spool into the neutral position. The portA is connected to port T. Thus a reduced pressure of 0bar is achieved for a de-energised valve. With the limita-tion the back pressure in the external drain pipe and/ortank pressure is the minimum available pressure. Thepressure present in the P line delivers the pilot oil to thepilot stage via a flow control valve.

When the proportional solenoid is energised, the pilotpressure is increased in the pilot pressure area, and themain spool moves against the spring until the connec-tion P-A opens. The regulation of the reduced pressureon connection A takes place by the constant comparisonof the actual pressure and the reference pressure of thepilot stage.

The pressure reducing valve consists of the main stagewith valve spools and the pilot stage. There is a flow limiterin the pilot stage. The pilot oil is provided internally fromthe P port. The drain is returned externally.

Typical applications are pressure systems, test equip-ment, or counterweight systems. The use in closed pres-sure control circuits is also possible.

FunctionThe valve spool is designed so that the connection B->Ais open in the neutral position and is closed in the work-ing position. The flow limiter provides a constant pilot oilflow from the B port to the pilot spool.

Characteristics

PE/PC10M

The proportional pressure reducing valves of the PE/PCseries have a proportional solenoid operated pilot stageand sliding spool main stage. The hydraulic function is inprinciple the same as the DWL/DWK series.

The power supply voltage and input command signalsare connected via a single seven-pin electrical plug con-nector. Input command signals can be in the range 0 to10V or 0 to 20mA, selected in the valve ordering code.Ramp times for increasing and decreasing pressure canbe independently set on two potentiometers.

MIN and MAX potentiometers allow the setting of theminimum pressure and the maximum pressure. Thesecan be adjusted to scale the set pressure range to corre-spond to the full range of the command input signal.
