Product Overview
The Rexroth 4WRZE25W8-220-73/6EG24N9K31/F1D3M (material number R901004329) is a high-response, pilot-operated proportional directional valve with integrated position feedback, designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Part of the Rexroth 4WRZE series, this valve features a size 25 (NG25) main stage with a W8 spool type and a rated flow of 220 L/min at a 10 bar (Δp) pressure differential per land. The valve is actuated by a proportional solenoid on one end (EG24 = 24 V DC) with spring return on the opposite end, and includes an N9 design variant with a concealed manual override. The integrated position feedback (F1D3M) enables closed-loop control of the main spool position, delivering exceptional repeatability, fast response, and minimal hysteresis. This valve is engineered for electro-hydraulic closed-loop systems requiring high dynamic performance and precise directional control of actuators, cylinders, and motors.
