The H-4WEH22E7X/6EW110N9EDA/B08D3V belongs to the WEH Directional Spool Valves series from Bosch Rexroth and directs fluid flow in automated hydraulic circuits. It uses a 4/3-way port configuration at nominal size NG25 to route pressure and return lines through a subplate-mounted interface. Connections match the ISO 4401-08-08-0-05 porting pattern, allowing interchange with standardized manifolds. A concealed manual override is included for local actuation when electrical control is unavailable. Internal pilot oil is taken from port P, while spent pilot oil exits externally through port Y to separate tank plumbing. Maximum operating pressure on ports P, A, and B is 350 bar, and the valve carries 450 l/min of flow on spool symbol E without excessive loss.
Control margins are defined by a maximum pilot pressure of 210 bar and a minimum of 10.5 bar for the spring-centered design. Port T withstands 250 bar, whereas port Y in the control section is limited to 160 bar. A pilot flow requirement of 35 l/min enables fast spool shifts for dynamic machinery cycles. The integrated pressure-reducing stage holds its setpoint at 45 bar to protect the pilot circuit from supply spikes. Fluorocarbon (FKM) seals resist high temperature fluids and many synthetic oils used in modern plants. With two solenoids installed, the spring-centered assembly weighs 11.9 kg, permitting straightforward handling during maintenance.
