Product Overview
The Rexroth 4WRZE25W6-325-73/6EG24N9EK31/F1D3M (Material Number R901040911) is a high-performance pilot-operated proportional directional valve from the proven 4WRZE series. It features a size 25 (NG25) main stage with a 4-way, 3-position spool design and is actuated by a proportional solenoid with integrated position feedback for precise, repeatable control of flow direction and magnitude. The valve regulates hydraulic flow proportionally to the electrical command signal, enabling smooth acceleration, deceleration, and positioning of actuators in demanding industrial motion-control systems. With a nominal flow capacity of 325 L/min at a 10 bar (1 MPa) pressure differential per land, this valve is engineered for high-flow, high-precision applications where accurate velocity and force control are essential.
