Product Overview
The Rexroth H-4WEH25J68/6EG24ETS2K4/B10D3 (material number R901205282) is a size 25 electro-hydraulic directional spool valve from the proven 4WEH series, engineered for pilot-operated control of start, stop, and direction of fluid flow in high-capacity industrial hydraulic systems. The main stage is actuated by a pilot directional valve that is shifted by a wet-pin DC solenoid, allowing the valve to switch large flows at high operating pressures with minimal electrical input. The “J” spool configuration provides a defined mid-position function, while the integrated spring return and detent arrangement ensure predictable spool positioning upon de-energization. With a nominal flow capacity of approximately 450 L/min and a maximum working pressure of 350 bar, this valve is a direct-fit, OEM-equivalent component for demanding manifold and subplate installations.
