Product Overview
The Rexroth 4WE 10 E51/HG24N9K4/M (Material Number R901390857) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE 10 series. Designed for controlling the start, stop, and direction of hydraulic fluid flow, this 4-way, 3-position valve features a spring-centered spool with two wet-pin AC solenoids. The “E51” spool type provides a specific center condition (closed center) for precise load holding and actuator positioning. With a nominal size of NG10 (CETOP 5 / ISO 4401-05), this valve is engineered for high-performance industrial hydraulic systems requiring reliable, repeatable directional control and fast response times.
