The 4WSE2EM6-2X/10B8ET315K17EV valve belongs to the 4WS Servo Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. It receives a ±10 mA command signal that proportionally controls spool position for precise actuator motion. The internal electronics present an input resistance of 1 kΩ so common motion controllers can drive the input without excessive load. A ±15 V DC supply powers the unit, and each rail draws 150 mA, supporting stable control without separate power conditioning. The assembly withstands operating pressures up to 315 bar and passes 10 l/min at a 70 bar differential, making it suitable for medium flow circuits. Its nominal size of 6 (NG06) matches the ISO 4401-03-02-0-05 mounting pattern, allowing direct installation on standard subplates.
The spool offers three switching positions to route flow left, right, or block ports when centered. Both pilot oil supply and pilot oil return are internal, reducing external piping and simplifying manifold layouts. FKM seals are used so the valve can handle mineral oil grades HL and HLP without leakage. Electrical connection is through a 7-pin round plug compliant with EN 175201-804, and with the mating connector fitted the enclosure achieves IP65 protection against dust and low-pressure water jets. The mass is 1.1 kg, permitting manual placement during maintenance or retrofit. Acting as a four-way directional servo valve, it meters flow to cylinders or motors accurately while fitting compactly on NG06 manifolds.
