Product Overview
The Rexroth 4WE 6 J70/HG24N9K4/B10 (material number R901108990) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE 6 series. Designed for controlling the start, stop, and direction of hydraulic fluid flow, this valve features a J70 spool configuration and is equipped with a high-performance 24 V DC wet-pin solenoid (HG24 designation) with a concealed manual override (N9) and a spring return (K4). The “B10” suffix indicates the specific electrical connection variant. Engineered for high cycle rates and precise switching in demanding industrial hydraulic circuits, this valve is a direct-fit replacement for OEM Rexroth components.
