The 4WEH10J4X/6EG24N9ETS2K4/B10V valve belongs to the WEH Directional Spool Valves series and is manufactured by Bosch Rexroth to control hydraulic actuators in automated equipment. It uses a 4-way, 3-position spool matched to the NG10 size interface. The unit manages flows up to 160 l/min and endures 280 bar at ports P, A, and B. Actuation is provided by a 24 V DC coil that mates with a DIN EN 175301-803 K4 connector, while a concealed N9 manual override allows local shifting. The mounting face follows the ISO 4401-05-05-0-05 pattern, and FKM seals guard against high-temperature or chemically aggressive fluids.
The pilot stage uses internal supply and return designated ET and must remain below a 250 bar maximum. Reliable movement requires 4.5 bar minimum at port P for internal channel X and at least 12 bar pilot pressure when the spool is spring-centered. System fluid cleanliness must be maintained at ISO 4406 20/18/15. A discharge-control feature marked S2 lets the user adjust switching time, and a Ø1.0 mm throttle insert coded B10 conditions pilot flow. These elements work together to provide consistent response without external damping components.
