Product Overview
The Rexroth 4WEH 25 J1X/6HG24N9ETK4/B10 (Material No. R901531183) is a high-performance electro-hydraulic directional spool valve from the renowned Rexroth 4WEH series. Engineered for pilot-operated directional control, this valve utilizes a solenoid-actuated pilot stage to control the main spool, enabling precise switching of high-flow hydraulic circuits with minimal electrical power. The “J1” spool configuration provides a specific flow path for controlled extension and retraction of actuators, while the “6HG24” pilot valve designation indicates a 24V DC high-performance solenoid with manual override. The “N9” identifies the electrical connector type, and “ETK4” specifies the throttle insert configuration for optimized pilot flow. With a nominal size of NG25 (DIN 24340), this valve is designed for demanding industrial applications requiring reliable, leak-free directional control of hydraulic fluid at pressures up to 350 bar. As a direct-fit replacement for OEM systems, the R901531183 ensures seamless integration into existing manifolds and hydraulic power units.
