The 4WS2EM10-5X/60B0T315K31CV-112 servo valve is part of the 4WS Servo Valves series from Bosch Rexroth and is used to meter hydraulic flow in closed-loop automation circuits. It is built in size 10 and delivers a rated flow of 60 l/min to drive cylinders or motors with consistent response. The metering edges are designed for a rated differential pressure of 70 bar, while the body withstands a maximum operating pressure of 315 bar. An analog command signal controls the armature, which draws a coil current of 30 mA against a coil resistance of 85 Ω. Electrical hookup is through an EN 175201-804 connector, allowing the valve to integrate with standard servo-drive wiring layouts.
Environmental sealing reaches IP65 when the mating connector is installed, protecting the electronics against dust and low-pressure water jets. The valve mounts on a subplate and follows the ISO 4401-05-05-0-05 pattern so it can replace or interchange with other size-10 components. Pilot oil is supplied externally and returned internally, avoiding separate drain lines in the manifold. Hydraulic fluid entering the unit must meet ISO 4406 18/16/13 cleanliness to prevent spool wear, and all dynamic seals are made of FKM for resistance to modern synthetic oils. The assembly weighs 3.56 kg, which suits direct installation on compact actuator blocks without extra support hardware.
