Servo Directional Valve 4WS2EM10-5X/5B11XHE315K31EV - Bosch Rexroth R901244995

A servo valve with internal pilot drain reacts to any back pressure in the tank line. This version takes pilot oil internally but drains it externally to an unpressurised line, while metering 5 l/min nominal flow at 9 l/min maximum.

Benefits

• Internal pilot oil supply with external pilot oil return, keeping the pilot chamber free of return line back pressure
• 5 l/min nominal flow, 9 l/min maximum flow, sized for small closed loop axes
• Direct actuation with internal spool position feedback, analog command value 30 mA/85 on 24 VDC
• 350 bar operating pressure, FKM seals, HL hydraulic fluid
• Size 10 to ISO 4401-05-05-0-05, 3 switching positions, 4.46 kg

Application

The choice wherever return filters, coolers, a long collecting return line build up a few bar of back pressure. In test benches, clamping axes the zero position of the valve stays stable as a result. The separate Y line runs to tank without pressure.
