The H-4WEH25P6X/6EW110N9K4/V valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series and directs hydraulic flow for automated actuators in industrial and mobile machinery. The nominal size NG25 supports a maximum flow of 300 l/min at 350 bar along port P, enabling fast response in high-volume circuits. Its porting pattern follows ISO 4401-08-08-0-05 so it mates with standard subplates. Ports p, a, and b withstand operating pressures up to 350 bar, while an external pilot oil supply and an external pilot oil return simplify circuit design. The external pilot return Y tolerates 160 bar, and the spring-centered spool begins to shift once pilot pressure exceeds 13 bar.
Electrical termination uses a DIN EN 175301-803 K4 connector, giving straightforward coil wiring during installation. A concealed manual override identified by code N9 lets technicians shift the spool manually during commissioning. The pilot stage handles pressures up to 250 bar, and the T port is rated for the same 250 bar to accept back-pressure. Six M12 × 60 screws secure the housing and must be tightened to 100 Nm to maintain seal compression. FKM seals resist high-temperature oils and many synthetic fluids, preserving leakage control over long duty cycles. With a mean time to dangerous failure of 100 years, the valve offers a high level of functional reliability for critical hydraulic automation tasks.
