Product Overview
The Rexroth 4WRZE 25E3-220-7X/6EG24N9ETK31/F1D3V (Material No. R901126880) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth 4WRZE series. Engineered for precise control of flow direction and magnitude in demanding industrial hydraulic systems, this valve utilizes a proportional solenoid on the pilot stage to infinitely vary the position of the main spool. This results in smooth, stepless control of actuator velocity and direction, making it an ideal choice for applications requiring high dynamic response, excellent repeatability, and precise force or position control. The “25” size designation indicates a nominal flow capacity of 250 L/min, while the “E3” spool type provides a specific flow characteristic optimized for position and velocity control loops.
