The 4WEH22E7X/6EW110N9ESK4/B10 belongs to the WEH Directional Spool Valves series from Bosch Rexroth and is used to route pressurized fluid in automated hydraulic circuits. It is built in size NG25, allowing adequate passage area for systems that need a high rate of flow, and matches the ISO 4401-08-08-0-05 porting pattern so it can bolt directly to standardized subplates. A maximum flow of 450 l/min supports large cylinders or motors, while the operating pressure at ports P, A, and B is limited to 280 bar to contain system forces safely. The spool is identified by symbol E, establishing specific crossover paths between supply and work ports during actuation. Switching time can be tuned through supply control marked as S, which lets technicians balance speed and shock levels. A throttle insert with a 1.0 mm bore restricts pilot flow for smoother shifting, and the pilot oil is taken internally, which removes the need for an external feed line.
An electrical connection conforming to DIN EN 175301-803 K4 provides a common interface for the two solenoids that drive the spool, and the assembled unit weighs 19.0 kg, which guides handling and mounting decisions. The valve attaches with six M12 × 60 screws, giving adequate clamping force to seal against pressure loads. System cleanliness must not exceed ISO 4406 20/18/15 so the precision-ground spool remains free from scoring and binding. Return flow from the pilot stage exits through an external Y port, keeping control oil separate from the main tank line. A spring-centered version requires at least 10.5 bar pilot pressure to shift, while the pilot circuit may be loaded up to 210 bar without damage. Port Y itself tolerates up to 160 bar, enabling installation in back-pressure environments that use elevated tank lines.
