The 4WEH22J7X/6EW110N9ETDAL/B10 directional valve is manufactured by Bosch Rexroth and belongs to the WEH Directional Spool Valves series. As a 4/3-way electro-hydraulic unit, it directs flow between four ports and provides three switching positions for automated circuits. The J spool geometry is held in its neutral position by a spring-centered arrangement, ensuring stable shutoff when pilot pressure is absent. With a nominal size of 25, the flow passages match manifolds for medium-capacity actuators. Internal pilot supply via port X feeds the control stage without external lines, while internal pilot return to port T simplifies tank routing. The ISO 4401-08-08-0-05 porting pattern allows direct mounting on standardized subplates. Fluid cleanliness must not exceed class 20/18/15 under ISO 4406 to protect the precision lands. A throttle insert with a 1.0 mm orifice, coded B10, can be fitted to moderate surge flow. The valve starts to shift once pilot pressure rises above 10.5 bar, which aligns with common low-pressure control pumps.
When actuated, the valve passes up to 450 l/min through the J spool channels, supporting high-volume cylinders or motors. Working ports A and B, along with pressure port P, withstand continuous pressures to 280 bar, letting the component run in heavy-duty systems. Tank port T is rated for 250 bar, so back-pressure builds can be tolerated without risking seal damage. The pilot stage accepts pressures up to 210 bar, providing a large control margin for rapid shifts. Achieving the shortest switching time requires 35 l/min of pilot flow, which the internal network delivers as long as the supply pump is sized accordingly. These limits define safe operation and ensure predictable performance in hydraulic automation.
