Servo Directional Valve 4WS2EM10-5X/75B11XHE315K31EV - Bosch Rexroth R901108851

Large flows raise pressure in the tank line, which an internally drained servo valve passes on to its pilot stage. This version drains pilot oil externally, holding its zero point while it controls 75 l/min nominal flow, up to 160 l/min in peak.

Benefits

• 75 l/min nominal flow, 160 l/min maximum flow in size 10
• External pilot oil return with internal supply, the answer to a return filter, a cooler in the tank line
• Internal spool position feedback for high repeat accuracy, analog command value 30 mA/85
• 350 bar operating pressure, 24 VDC supply through a 7-pole connector (6 + PE)
• FKM seals, HL hydraulic fluid, 4.4 kg

Application

The valve serves presses, forging plants, test benches with high throughput on a closed loop axis. A separate pilot drain becomes mandatory as soon as a shared return of several consumers builds up pressure. Mounting is on an ISO 4401-05-05-0-05 subplate.
