The 4WS2EM10-5X/60B0T210K31CV-112 is a servo valve in the 4WS Servo Valves series manufactured by Bosch Rexroth. Designed for hydraulic automation, it meters fluid to actuators with proportional control signals. The mounting interface conforms to ISO 4401-05-05-0-05 so it fits standard CETOP 05 subplates. A rated flow of 60 l/min at a 70 bar differential supports mid-range servo cylinders, while ports p, A, and B tolerate pressures up to 315 bar for heavy-duty systems. The pilot stage accepts supply pressures up to 210 bar, allowing independent control line design. At 1 % spool stroke the pressure gain reaches at least 30 % of the supply pressure, giving high stiffness. Response sensitivity stays within 0.2 % so small command changes create measurable flow, and the range of inversion remains below 0.3 % to minimize null offset. Dither-optimized hysteresis does not exceed 1.5 %, reducing steady-state error.
The valve carries an IP65 protection class, sealing the housing against dust and low-pressure water jets in typical machine enclosures. Electrical connection follows EN 175201-804 pattern K31, and the dedicated mating connector is part number R900223890 for quick field wiring. Each coil draws a rated current of 30 mA, presents a resistance of 85 Ω, and exhibits a series inductance of 1.0 H, parameters that simplify drive-amplifier tuning. Hydraulic cleanliness must reach ISO 4406 code 18/16/13 to prevent spool wear. The assembled unit weighs 3.56 kg, which eases mounting on manifolds without extra support.
