The 4WEH22D7X/6EW110N9S2DK25L directional spool valve is built by Bosch Rexroth in the WEH Directional Spool Valves series. It diverts hydraulic flow in automated machinery where remote pilot actuation is required. The valve is supplied in size 25 (W.H 22) and matches the ISO 4401-08-08-0-05 porting pattern for easy manifold integration. A rated operating pressure of 280 bar is allowed at ports P, A, and B, while a maximum pilot pressure of 210 bar feeds the control stage. When the assembly uses a two-spool layout with an external X port, the unit accommodates up to 450 l/min of main flow; 35 l/min of pilot flow is needed to move the spool. The minimum pilot pressure for a two-spool configuration is 11 bar, ensuring reliable shifting even with viscous fluids.
Installation details are governed by six M12×60 screws to ISO 4762 strength class 10.9, each tightened to 100 N·m with a tolerance of ±10 %. The single-solenoid version weighs 11.5 kg, so normal lifting tools are sufficient during mounting. A body coating not exceeding 100 µm provides surface protection against moisture and light corrosion throughout the valve’s mean time to dangerous failure of 100 years. Approved storage limits range from +5 °C to +40 °C, and the valve can operate in ambient conditions between −20 °C and +50 °C without derating. These thermal capabilities, combined with the stated mechanical and flow ratings, allow the valve to serve in high-duty hydraulic automation circuits that demand consistent direction control.
