The 4WS2EM6-2X/5B12ET315K17EV is produced by Bosch Rexroth for the 4WS Servo Valves series and modulates hydraulic flow in closed-loop automation. It is built in nominal size 6, and its mounting interface follows ISO 4401-03-02-0-05 for direct manifold installation. The valve meters a nominal flow of 5 l/min yet can pass up to 48 l/min during transient demand. A maximum operating pressure of 315 bar permits use in high-pressure circuits. Both pilot oil supply and pilot oil return are internal, removing the need for external pilot lines. Reliable service depends on fluid filtered to ISO 4406 Class 18/16/13. Command input is an analog signal, allowing proportional control from standard motion controllers.
The electromagnetic section draws a nominal coil current of 50 mA, and the winding resistance is 85 Ω, values that help size the drive amplifier. Dynamic behavior changes with wiring: inductivity is 0.25 H in parallel connection and 1 H in series connection. Electrical interface is via a K17 connector, and when mated the enclosure attains an IP65 degree of protection against dust and water jets. All seals are made from FKM to tolerate aggressive hydraulic fluids and elevated temperatures. These characteristics support accurate spool positioning and maintain leakage integrity during continuous duty.
