The 4WS2EM10-5X/60B11T315K31CV servo valve is manufactured by Bosch Rexroth in the 4WS Servo Valves series. It modulates hydraulic flow and pressure in automated motion control loops. Valve size 10 sets the body dimensions for medium-capacity manifolds, and a rated flow of 60 L/min at a 70 Bar differential delivers the volume required by cylinders and motors. The design tolerates a maximum operating pressure of 315 Bar to suit high-pressure power units. Control is based on an analog input signal; each coil draws 30 mA through a resistance of 85 Ohm to generate spool-shifting force. A parallel coil inductance of 0.25 H limits the current rise rate and smooths electromagnetic actuation. The ISO 4401-05-05-0-05 porting pattern lines up with standard sub-plates for straightforward installation.
The electrical interface follows EN 175201-804 (K31), and the mating connector R900223890 completes the plug-in connection for field wiring. When the coils are wired in series, an inductance of 1.0 H dampens current changes and maintains synchronized movement. Pilot supply can be taken externally while return is internal, offering flexibility in circuit layout. A mechanical return system recenters the spool once the drive signal is removed. The enclosure meets IP65 so dust and low-pressure water jets cannot reach internal components, and FKM seals maintain fluid integrity against common hydraulic oils. The assembly weighs 3.56 kg, which aids manual handling during manifold mounting.
