The 4WEH32HD6X/OF6EW110N9TS2DAL valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It uses the NG32 size body with a 4-way configuration so pressure port P can connect to either work port A or B. A D-type spool offers two hydraulic end positions, and a hydraulic return circuit re-centers the spool when pilot pressure is removed. The main stage shifts through a high-power 6E pilot valve whose coil is rated for 110 VAC at 50/60 Hz. Service personnel can actuate the element with a concealed N9 manual override during setup or power loss. The valve passes up to 1100 l/min while withstanding 350 bar at ports P, A, and B. It bolts to manifolds that follow the ISO 4401-10-09-0-05 interface.
Pilot oil enters through external port X and returns internally to tank via port T, removing the need for a separate drain line. Reliable shifting starts at a pilot pressure of 5 bar, and the pilot circuit remains safe up to 250 bar. Port T tolerates 315 bar so the unit can handle elevated back-pressure conditions. These pressure limits ensure consistent performance when control lines are long or system loads vary.
