The 4WE6D6X/OFEG24NK4/B08 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to actuators in automation systems while fitting compact manifolds because its nominal size is 6. Four working ports provide supply, return, and two actuator lines for standard four-way control. The subplate interface follows porting pattern ISO 4401-03-02-0-05, allowing direct mounting on common bases. A 24 V DC coil energizes the high-power wet-pin solenoid, which shifts the spool under load. Spool position is held by a detent so continuous power is unnecessary once the position is reached. A manual override lets technicians move the spool during commissioning or power loss, and the valve can be installed in any orientation to simplify piping layouts.
It handles pressures up to 350 bar on the P, A, and B lines and withstands 210 bar on the tank port, supporting high-pressure circuits while returning oil safely. A flow capacity of 80 l/min in direct-current operation accommodates medium-sized actuator speeds. The throttle insert at port P with a 0.8 mm orifice (B08) limits inrush flow to reduce pressure spikes. An IP65 enclosure shields the solenoid and terminals from dust and water jets, and the electrical connection follows DIN EN 175301-803 K4 for quick plug-in wiring. Fluid cleanliness must meet ISO 4406 20/18/15 to protect the precision spool fit. The MTTFd is 300 years, indicating long statistical service life.
