The H-4WEH22J7X/6EG24N9ETK4/B10D3 valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series. It directs hydraulic flow in automated circuits using electro-hydraulic actuation, so electrical signals move the pilot stage to shift the main spool. The pilot solenoids accept a 24 V DC supply, and the connection is made through a DIN EN 175301-803 K4 plug to match common cabinet wiring. A nominal size of NG25 provides a passage area that supports up to 450 l/min when symbol J is selected, helping builders handle large flow rates with moderate pressure drop. The ISO 4401-08-08-0-05 porting pattern allows direct mounting on standard subplates, while an overall weight of 11.9 kg simplifies manifold installation without lifting equipment.
The spool is spring-centered so it returns to the neutral position as soon as pilot pressure is removed, maintaining a fail-safe state in the circuit. Working lines p, a, and b can be loaded to 350 bar, and port T withstands 250 bar, allowing the valve to operate in high-pressure systems. The pilot stage functions between 12.5 bar and 210 bar, giving designers a broad control range. Pilot oil is taken internally from port ET and returned internally to T, eliminating external hoses. A D3 pressure-reducing valve limits secondary pilot pressure to 45 bar to protect the solenoids, and a B10 throttle insert with a 1.0 mm orifice moderates pilot flow to prevent unstable spool movement.
