Servo Directional Valve 4WS2EM10-5X/30B11XHE315K31EV-102 - Bosch Rexroth R901439792

In a high bandwidth control loop the dead time of the valve sets the achievable dynamics. The directly actuated 4WS2EM10-5X/30B11XHE315K31EV-102 works without an upstream main stage, providing 30 l/min nominal flow at up to 350 bar.

Benefits

• Direct actuation without a pilot-operated main stage shortens response time in the loop.
• 30 l/min nominal flow in size 10, rated to a maximum flow of 60 l/min.
• Analog command value 30 mA/85 from external electronics, 24 VDC supply through a 7-pole connector (6 + PE).
• Internal pilot oil supply with external pilot oil return, 4 switching positions across 2 ports.
• FKM seals for higher oil temperatures, 3.88 kg, CCC-Ex conformity with an Ex TR type examination certificate.

Application

Servo valves of this class sit in materials testing machines, motion simulators as well as rolling mill stands where force or travel is corrected at high frequency. The external pilot oil return keeps the pilot stage clear of pressure surges from the tank line. Control electronics are supplied separately to match the machine.
