Product Overview
The Rexroth 4WRZE25E325-73/6EG24N9ETK31/A1M (material number R901017352) is a high-performance pilot-operated proportional directional valve from the Rexroth WRZE series, designed for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 25 (NG25) nominal flow path and a 4-way, 3-position spool configuration, this valve regulates actuator speed and direction proportionally to the electrical command signal applied to its integrated proportional solenoids. The “E325” spool designation indicates a specific progressive flow characteristic with defined metering geometry, while the “6EG24” solenoid code denotes 24 V DC wet-pin proportional solenoids with integrated position feedback for closed-loop control accuracy. The valve is equipped with a spring-centered spool return and a pilot stage that amplifies the control signal to drive the main spool with high dynamic response. As a core component in electro-hydraulic control loops, the 4WRZE25E325-73 is engineered for applications requiring smooth acceleration, deceleration, and position holding of hydraulic actuators under varying load conditions.
