Product Overview
The Rexroth 4WRZE 25E3-220-71/6EG24N9ETK31/F1D3V (Material Number R901126880) 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, making it a core component in closed-loop and open-loop motion control systems. The valve utilizes a two-stage design in which a proportional pilot valve actuates the main spool of a high-flow directional stage, delivering precise, continuously variable flow control with minimal hysteresis and excellent repeatability. With an NG25 (size 25) main stage and a rated flow capacity of approximately 220 L/min at a 10 bar pressure drop per land, this valve is engineered for demanding industrial applications requiring accurate velocity, position, and force control of hydraulic actuators.
