4WEH32G6X/6EW110N9DA

The 4WEH32G6X/6EW110N9DA directional spool valve is built by Bosch Rexroth within the WEH Directional Spool Valves series. Designed for hydraulic automation, it diverts pressure lines through an electro-hydraulic actuation system that minimizes operator effort. Size NG32 identifies a 32 mm nominal flow path suited to high-capacity circuits. A subplate mounting interface lets the unit drop into standardized manifolds for quick service exchange. The High-Power 6E pilot valve supplies the control force needed to shift the main spool without direct mechanical input. Because the pilot oil supply is external, supply pressure can be optimized independently of main line conditions, and an external pilot oil return keeps warm pilot fluid out of the tank return gallery. Electrical power reaches the pilot coil through a DIN EN 175301-803 (K4) connector that streamlines wiring inside machine cabinets.

A concealed manual override permits technicians to move the spool during commissioning or power loss without exposing moving parts. When system pressure reaches 280 bar, the valve can pass up to 650 l/min, meeting demands of rapid-actuation cylinders. The pressure rating for ports P, A, and B is also 280 bar to maintain uniform safety margins across the flow paths. The pilot circuit endures a maximum of 250 bar, yet a three-position spring-centered model only requires 8.5 bar pilot pressure to initiate a shift, reducing load on auxiliary pumps. Pilot volume of 29.4 cm³ determines the quantity of fluid that must be displaced by the pilot stage and therefore influences switching speed and energy usage. Together these pressure and volume limits define the dynamic performance envelope for high-cycle industrial presses and large mobile machines.
