Product Overview
The Rexroth 4WE 10 M50/HG24N9K4/M (Material Number R901401553) is a high-performance solenoid-operated directional spool valve from the proven 4WE series, engineered for precise control of start, stop, and direction of hydraulic fluid flow in industrial power units. Featuring a robust three-position, four-way (4/3) spool design with a closed-center (M-type) configuration, this valve directs pressurized flow to the actuator ports while blocking the pressure gallery in the neutral position. The unit is actuated by a wet-pin AC/DC solenoid (24 V DC) with a concealed manual override, designated by the N9K4 solenoid variant, ensuring reliable shifting and long service life in continuous-duty hydraulic circuits. As a direct-operated directional control valve, it delivers fast response, low pressure drop, and dependable switching performance across a wide range of demanding industrial applications.
