Product Overview
The Rexroth 4WRZE 25 W8-220-72/6EG24N9EK31/F103M (Material Number R900757604) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series. It is designed to control the direction and magnitude of hydraulic flow in proportion to an electrical input signal, enabling precise, stepless velocity and position control of actuators in demanding industrial systems. The valve utilizes a two-stage design in which a proportional pilot valve with a wet-pin DC solenoid actuates the main spool of a high-flow second stage, delivering smooth, continuous flow metering with minimal hysteresis and excellent repeatability. With a nominal size of NG25 and a rated flow capacity of approximately 220 L/min at a 10 bar pressure drop per land, this valve is engineered for high-performance motion control where fast response, fine resolution, and dependable long-term operation are essential.
