The 4WEH10J4X/6EG24N9ES2K4/B10D3 valve is produced by Bosch Rexroth within the WEH Directional Spool Valves series to direct flow in hydraulic automation circuits. It uses an NG 10 body and mounts on an ISO 4401-05-05-0-05 pattern for compatibility with standard subplates. Pilot solenoids are energized at 24 V DC, and wiring is completed through a DIN EN 175301-803 connector. The J-spool passes up to 160 l/min while ports P, A, and B withstand 280 bar. Port T shares the same 280 bar limit, and the external Y drain is rated at 210 bar. The pilot stage tolerates 250 bar and requires at least 12 bar to maintain the centered three-position function.
Switching time can be tuned by a discharge-control adjustment, and a concealed manual override permits local actuation during setup or power loss. The pilot cavity volume is 2.04 cm³, which influences response time, and a 1.0 mm throttle insert can be installed to refine damping. A D3 secondary circuit is limited to 45 bar to protect auxiliary loads. The assembly, including two centering solenoids, weighs 6.8 kg, providing manageable handling during manifold installation.
