4WRKE10W6-50L-3X/6EG24TK31/A1D3M

The 4WRKE10W6-50L-3X/6EG24TK31/A1D3M valve belongs to the 4WRKE Directional Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic position and force control. It is built around nominal size 10, which dictates the mounting interface and supports a nominal flow of 50 L/min at a differential pressure of 10 bar. For higher demand cycles the design allows a maximum permissible flow of 170 L/min, while the ports withstand operating pressures up to 315 bar on P, A, and B lines. The valve receives control energy through a 24 VDC supply and interprets a ±10 V command signal for spool positioning; feedback is provided by an identical ±10 V actual value output to enable external controllers to verify spool displacement. A removable coil solenoid simplifies maintenance because the actuator can be replaced without opening the hydraulic section. Hydraulic pilot oil is supplied externally, and the pilot drain is routed internally, reducing pipework on the tank side.

Electrical integration uses a connector that follows DIN EN 175201-804, ensuring compatibility with standard machine wiring looms. The housing carries an IP65 enclosure rating, so dust ingress and low-pressure water jets do not affect operation in typical industrial environments. Average power consumption is 24 W during steady-state modulation, with short-term peaks reaching 72 W when large spool movements are commanded; this information aids power budget calculations in multi-axis systems, and the gap between the two figures guides sizing of thermal paths around the coil. NBR seals are fitted to withstand common mineral oils and maintain leakage control over the specified pressure range, extending service intervals. The complete assembly weighs 8.7 kg, which influences manifold support requirements and lifting considerations during service work inside confined machines.
