The H-4WEH25E6X/6EG24N9ETDK25L/B10D3V valve belongs to the WEH Directional Spool Valves series and is manufactured by Bosch Rexroth. It serves as an electro-hydraulic unit for directing fluid flow in automated circuits. The 4-way design provides separate pressure, return, and two service ports, while the spool offers three positions for neutral and actuation states. Nominal size 25 passages support medium to high flow rates, and a 6E pilot control valve shifts the main stage. The pilot solenoid operates on 24 V DC for straightforward electrical integration. A concealed N9 manual override permits local shifting during setup without exposing moving parts. Surge damping is handled by a 1.0 mm throttle insert designated B10.
Rated capacity reaches 650 l/min with symbol E at 350 bar, matching high-throughput demands. The main stage tolerates a maximum operating pressure of 350 bar, while the pilot circuit is limited to 250 bar and requires at least 13 bar to center the spring-returned spool. Internal supply and internal return of pilot oil, coded ET, remove the need for external drain lines. The ISO 4401 porting pattern aligns the mounting surface with standard manifolds, and FKM seals resist aggressive fluids and elevated temperatures. Secondary pressure at port d3 is capped at 45 bar to protect downstream devices. Together, these parameters enable consistent control of high-pressure flow in automated hydraulic machinery.
