4WRKE10E100L-3X/6EG24ETK31/A5D3M

The 4WRKE10E100L-3X/6EG24ETK31/A5D3M is a directional valve from Bosch Rexroth in the 4WRKE Directional Valves series. It meters hydraulic flow and pressure to automate actuator movement in industrial systems. The valve is built to nominal size 10, matching mounting interfaces where moderate flow is required. Its porting pattern follows ISO 4401-05-05-0-94 so it fits standard subplates without modification. A maximum operating pressure of 315 bar allows use in high-pressure circuits, while a nominal flow of 100 L/min at a 10-bar differential provides predictable performance in control loops. When greater demand arises, the design still permits up to 170 L/min so transient loads do not cause saturation. Both pilot oil supply and pilot oil drain are internal, reducing external piping and minimizing leak points. The main stage requires fluid cleanliness of 20/18/15 according to ISO 4406 to protect the precision spool. The assembled unit weighs 8.7 kg, enabling single-person handling during installation.

The valve’s electronics operate from a 24 VDC supply, and the control board draws up to 1.5 A so cabinet power sizing can be set correctly. A maximum consumption of 72 W defines the thermal load that must be dissipated inside the enclosure. Position commands are accepted as a ±10 V analog signal, giving symmetric control around the null position for bidirectional metering. An enable line that accepts 4–24 V allows the machine controller to switch the stage on or off without cycling the main power feed. Electrical connection is made through a plug conforming to DIN EN 175201-804, ensuring compatibility with common molded cable assemblies. When the connector is attached, the housing attains an IP65 protection level, keeping dust and low-pressure water jets from reaching the electronics in typical factory environments. These electrical features combine with the hydraulic data described earlier to support reliable closed-loop motion control in presses, test rigs, and production tooling.
