Product Overview
The Rexroth 5-4WE 10 W33/CG24N9K4 (Material No. R900563805) is a high-performance, direct-operated solenoid directional spool valve from the proven 4WE series, size 10 (NG10 / CETOP 5). Designed for controlling the start, stop, and direction of fluid flow in industrial hydraulic systems, this four-way, three-position (4/3) valve features a spring-centered spool with a “W33” spool type, providing a closed-center configuration with restricted flow characteristics for precise actuator positioning. The valve is actuated by a wet-pin AC/DC solenoid (CG24N9K4 designation) with a nominal voltage of 24 V DC, delivering fast, reliable switching response. With a maximum operating pressure of 350 bar and a nominal flow capacity of up to 80 L/min, this valve is engineered for demanding industrial applications requiring high switching reliability, low leakage, and long service life.
