Servo Directional Valve 4WS2EM10-5X/30B11T210K31EV - Bosch Rexroth R901518119

Not every test rig runs at the top of the pressure range, many work in a middle band and need clean control there. The 4WS2EM10-5X/30B11T210K31EV draws pilot oil externally, returns it internally and provides 30 l/min nominal flow.

Benefits

• 30 l/min nominal flow at up to 60 l/min throughput, matched to medium-size cylinders in a closed loop.
• External pilot supply, internal return, the pilot stage stays decoupled from load pressure.
• 315 bar maximum operating pressure, ISO 4401-05-05-0-05 pattern in size 10.
• 3.6 kg weight with FKM seals, exchange on the rig is possible without lifting gear.
• 30 mA command through external electronics, the valve connects to existing servo controllers.

Applications

The valve is used in materials testing machines, fatigue rigs and control axes whose setpoint is corrected continuously. External supply keeps the pilot stage fed even when the working circuit briefly loses pressure. The 7-pole connector to EN 175201-804 links the valve to the controller.
