The 4WE6J6X/EW110N9DA/B10VSO525 directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated systems. The valve is built in size 6 to fit standard CETOP 03 manifolds and maintain a compact envelope. A high-power wet-pin solenoid generates reliable actuation force while keeping the coil isolated from the fluid. Because the coil is detachable, field replacement can be performed without opening the pressure housing. The coil is designed for 110 V AC at 50 or 60 Hz so it can connect directly to industrial control power. The unit handles operating pressures up to 350 bar, supporting high-pressure circuits, and passes up to 60 l/min to cover medium flow demands. It can be installed in any position, which eases machine layout, and the IP65 housing protects the electrics against dust and water spray.
The concealed N9 manual override allows local shifting when power is lost while reducing the risk of accidental activation; this backup is rated for tank pressures up to 50 bar. The tank port itself may see 160 bar, so return lines can tolerate moderate back-pressure without compromising function. Mounting screws must be tightened to 7 Nm to secure the valve to the manifold and maintain sealing integrity. A throttle insert with a 1.0 mm orifice (code B10) can be placed in the P port to smooth acceleration and limit surge. Flow paths follow the ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability with other size 6 components. FKM seals resist high temperature and aggressive hydraulic fluids to extend service life. The calculated mean time to dangerous failure is 300 years, supporting safety assessments for long-term installations.
