4WEH32H6X/6EG24N9S2DA

The 4WEH32H6X/6EG24N9S2DA directional spool valve is produced by Bosch Rexroth within the WEH Directional Spool Valves series. It directs hydraulic flow so cylinders or motors receive pressure or return flow according to electrical commands in automated machinery. The valve is built in NG32 size, providing a maximum flow capacity of 1100 l/min for high-volume circuits. It connects to manifolds through the ISO 4401-10-09-0-05 interface, allowing standardized mounting on subplates. A pilot control stage identified as the 4WE 6 high-power valve shifts the main spool under load. The solenoid coils require a 24 V DC supply which suits common machine control voltages. A maximum operating pressure rating of 350 bar permits use in heavy-duty presses and injection equipment.

Pilot pressure limits and adjustment features define switching performance. The pilot stage tolerates up to 250 bar while the main spool recenters once pilot pressure drops below 8.5 bar in the pressure-centered version. For quickest actuation the pilot circuit must deliver 45 l/min, ensuring the spool traverses its stroke without delay. Switching time can be reduced further through the S2 discharge adjustment that vents pilot oil rapidly after de-energization. Operators can actuate the valve locally through a concealed N9 manual override when electrical power is absent. These elements combine to give the 4WEH32H6X/6EG24N9S2DA consistent response in high-cycle hydraulic automation where precise directional control is required.
