Product Overview
The Rexroth 4WE 10 E50/HG24N9K4/M (Material Number R901390857) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series. Designed for controlling the start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a robust three-position, four-way (4/3) spool configuration with a closed-center (E) spool type. The valve is actuated by a high-performance 24 V DC wet-pin solenoid (HG24) with a nominal voltage of 24 V DC, and includes a concealed manual override (N9) for emergency operation. The K4 designation indicates an ISO 4401-05 (NG10 / CETOP 5) mounting interface with a standard subplate pattern. With a maximum operating pressure of 350 bar and a nominal flow capacity of up to 120 L/min, this valve is engineered for precise directional control in demanding industrial applications requiring reliable, repeatable performance.
