The 4WEH22J7X/6EG24N9DA/B08 is a hydraulic valve manufactured by Bosch Rexroth for the WEH Directional Spool Valves series. Designed to route high-pressure oil in automated machinery, the unit employs a 4-way version so four ports can be connected to supply, return, and two actuator lines. Its nominal size of 25 enables large flow capacity while maintaining compatibility with manifolds of the same designation. The spool marked with symbol J defines the internal grooves that produce a maximum flow of 450 l/min at 280 bar, supporting rapid cylinder movements. A porting pattern of ISO 4401-08-08-0-05 allows direct mounting on subplates standardized across production lines. Actuation is provided by an integrated 6E pilot valve; pilot oil is taken internally through channel X, then returned externally via port Y to minimize back pressure in the pilot circuit. Operating pressure can reach 280 bar on ports P, A, and B without reducing service life, giving designers flexibility for heavy-duty drives.
The electrical interface uses a 24 V DC coil voltage, aligning with common machine control supplies and reducing the need for separate power converters. A concealed manual override identified by code N9 lets maintenance staff shift the spool mechanically while keeping the push pin protected from debris. The built-in throttle insert with a 0.8 mm orifice, labeled B08, damps pilot oil surges so switching shocks are limited. Pilot integrity is further managed by a maximum allowable pilot pressure of 210 bar and a minimum of 10.5 bar for spring-centered return, ensuring the valve responds predictably across a broad supply range. Hydraulic cleanliness must not exceed ISO 4406 class 20/18/15; this particle limit safeguards the precision clearances inside the spool and seat. With two solenoids installed and the centering springs in place, the assembly weighs 19.0 kg, a consideration when selecting mounting hardware or planning service handling.
