The 4WEH10HD4X/OF6EG24N9EK4/B10 valve belongs to the WEH Directional Spool Valves series and is produced by Bosch Rexroth for circuit control in hydraulic automation. Its electro-hydraulic actuation lets an electrical signal shift the pilot stage while hydraulic pressure moves the main spool. A 4-way configuration provides four working ports to guide pressure and return flow. The NG10 size matches subplates designed for 10 mm nominal passages. A 24 V DC coil connects directly to common machine control voltage. The ISO 4401-05-05-0-05 porting pattern maintains compatibility with standard mounting faces. Pilot oil is supplied internally from port P, and it returns externally through port Y to minimize restriction. A B10 throttle insert in port P limits pilot flow to smooth spool movement.
The main spool is returned hydraulically, so system pressure resets the valve without mechanical springs. A detent mechanism in the pilot section holds the spool position until a new command is given. The concealed manual override allows local actuation while keeping external dimensions compact. Ports P, A, and B withstand up to 350 bar, enabling use in high-pressure systems, while port Y is limited to 210 bar to protect the pilot return path. Mounting screws should be tightened to 12.5 Nm to secure the valve and maintain sealing. The design attains an MTTFd of 100 years, supporting long service life in safety analyses. Fluid cleanliness must reach ISO 4406 class 20/18/15 to protect the spool and reduce wear.
