Electro-ProportionalValvesSection Introduction

This section gives basicspecifications for the com-plete line of Vicker’s screw-inproportional control valves.Its purpose is to provide aquick, convenient referencetool when choosing propor-tional valves or when design-ing a system using thesecomponents.

The EPV10 has several out-standing performance fea-tures which give it a uniqueposition in the screw-in car-tridge valve market. Valvegain linearity, flow forcepressure compensation char-acteristics above 20 bar (300psi) and low internal leakage.

The EPV16 is a proportionallycontrolled two-way poppettype valve. The main poppetamplifies a small flowthrough the pilot circuit andis comparable to a transistor.As the transistor uses smallcurrents to control larger cur-rents, the hydraulic valvetransistor or VALVISTORuses the pilotflow to controlthe main stage flow withservo-like response flow tocontrol.

The EFV1 is a proportionallycontrolled two-way, spooltype flow control valve.Technically the valve is notpressure compensated, butat high differential pressuresit is partially flow force pres-sure compensated.

The EFV2 is a three port,pressure compensated, pro-portional flow control valve.The valve can be used as apriority flow regulator, withregulated flow being sup-plied to port 3 and excessflow being by-passed to port2. If port 2 is blocked thevalve functions as a restric-tive, 2 way, pressure com-pensated flow regulator.

The ERV1-10 is an electric,proportionally controlled,internally pilot operated,spool type screw-in reliefvalve. It is capable of han-

designed to be easily con-trolled by the simplest of DCelectrical devices such as a12 volt battery and a poten-tiometer.

Varying the voltage at thecoil is one of the simplestmeans of control available.Any of the Vickers DC coilswill work on most of thesevalves simply by varying thevoltage between 0 and 75%of the rated coil voltage. Itshould be noted that as theoperating temperature of acoil increases, the solenoidforce decreases. Therefore ifthe voltage is held constantas the coil heats up thenvalve pressure (or flow) willchange.

Electrical current controlswith PWM are recomendedfor all Eaton proportionalvalves.

Closed-loop electrical controlwith feedback from theparameter to be monitoredwill provide the most accu-rate control.

Description

The EFV1-10*-0** is a nor-mally open, unidirectional,uncompensated, spooltype, two way, proportionalflow control, screw-in car-tridge valve.

Operation

The valve is controlled bycurrent supplied to the coil.At zero current, the valve isfully open from port 2 toport 3. At 1500 to 1600 mA(12V coil) the valve is fullyclosed. Port 1 is used forpressure balancing thespool and armature andmust be blocked in allcases.

The maximum intendedpressure drop is 300 PSID.At pressure drops above300 PSID, almost noincrease in flow is obtained.The intended flow directionis from port 2 to port 3.Operation of the valve withflow from port 3 to port 2will produce flow vs currentand flow vs pressure dropcurves that are significantly

different from thoseobtained with flow fromport 2 to port 3.

Since the spool and arma-ture are pressure balanced,

the operating pressuredoes not affect the operat-ing characteristics of thevalve. The operating pointof the valve is determinedonly by current, pressuredrop and temperature.

Description

The EFV1-10*-C** is a nor-mally closed, unidirectional,uncompensated, spooltype, two way, proportionalflow control, screw-in car-tridge valve.

Operation

ThThe valve is controlled bycurrent supplied to the coil.At zero current, the valve isfully closed from port 3 toport 2. At 1500 mA (12Vcoil) the valve is consideredfully open. This is the maxi-mum intended current levelfor use in applications. Port1 is used for pressure bal-ancing the spool and arma-ture and must be blocked inall cases.

The maximum intendedpressure drop is 300 PSID.At pressure drops above300 PSID, almost noincrease in flow is obtained.The intended flow directionis from port 3 to port 2.Operation of the valve withflow from port 2 to port 3will produce flow vs currentand flow vs pressure dropcurves that are significantly

Description

The EFV1-12*-C** is anormally closed, unidirec-tional, uncompensated,spool type, two way, pro-portional flow control,screw-in cartridge valve.

Operation

The valve is controlled bycurrent supplied to the coil.At zero current, the valve isfully closed from port 3 toport 2. At 1500 mA (12Vcoil) the valve is consideredfully open. This is the maxi-mum intended current levelfor use in applications. Port 1 is used for pressurebalancing the spool andarmature and must beblocked in all cases.

The maximum intendedpressure drop is 300 PSID.At pressure drops above300 PSID, almost noincrease in flow is obtained.The intended flow directionis from port 3 to port 2.Operation of the valve withflow from port 2 to port 3will produce flow vs currentand flow vs pressure dropcurves that are significantlydifferent from those

obtained with flow fromport 3 to port 2.

Since the spool and arma-ture are pressure balanced,the operating pressure doesnot affect the operatingcharacteristics of the valve.The operating point of thevalve is determined only bycurrent, pressure drop andtemperature.

Description

The EFV2-12*-0 is a nor-mally open, three port,pressure compensated,proportional flow controlvalve. The valve can beused as a priority flow regu-lator, with regulated flowbeing supplied to port 3and excess flow being by-

passed to port 2. If port 2 isblocked the valve functionsas a restrictive, 2 way, pres-sure compensated flow reg-ulator.

Operation

Current supplied to the coilcontrols the valve. At zerocurrent, the valve is fullyopen from port 1 to port 3.At 1600 mA (12V coil) thevalve is fully closed. Thevalve will regulate flow outof port 3 regardless of

downstream system pres-sure. As current is increasedto the solenoid the flow outof port 3 will decrease.

Description

The EPRV2-8 is a proportion-al, pressure reducing-reliev-ing, sliding spool, electricallycontrolled, screw-in cartridgetype valve.

Operation

In the de-energized position,pressure inlet port 2 isclosed and reduced pres-sure port 1 is open to returnport 3. As electrical current

is increased, port 2 opensto port 1 and port 3 closes,proportionally increasingpressure at port 1. If thepressure at port 1 exceeds

the setting of the valve,the spool will shift furtherand relieve to port 3.

Description



Operation

This valve remains openfrom port 2 to port 1 (port 3must be vented). Once thepredetermined pressure is

reached at port 1, the spoolshifts to restrict the inletflow at port 2, which regu-lates the pressure at port 1.

If the pressure at port 1exceeds the setting of thevalve, the spool will shift far-ther and relieve to port 3.
