Product Overview
The Rexroth 4WRZE25W6-220-73/6EG24N9ETK31/F1D3M (Material Number R900703118) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series. It is engineered to control both the direction and the magnitude of flow in proportion to an electrical input signal, making it a core component in closed-loop and open-loop hydraulic control systems. The valve utilizes a two-stage design in which a proportional pilot valve actuates the main spool of a size 25 directional valve, delivering smooth, infinitely variable metering of actuator motion. With integrated position feedback of the main spool, the 4WRZE platform provides exceptional repeatability, minimal hysteresis, and fast dynamic response, positioning it as a preferred solution for demanding industrial motion control tasks where precise velocity and position regulation are essential.
