Product Overview
The Rexroth 4WRZE25W8-325-73/6EG24N9EK31/F1D3M (material number R900753993) is a high-response, pilot-operated proportional directional valve with integrated position feedback, part of the Rexroth 4WRZE series of proportional valves. It is designed to control the direction and magnitude of hydraulic flow in proportion to an electrical input signal, making it a core control element in demanding industrial hydraulic systems. The valve features a size 25 (NG25) nominal flow path, a spool type “W8” with progressive flow characteristics, and a rated flow capacity of 325 L/min at a 10 bar (Δp) pressure differential per metering edge. The integrated control electronics (type 6EG24N9EK31) provide 24 VDC supply, a command signal interface, and an enable input, while the “F1D3M” suffix denotes the specific electrical and spool position feedback configuration. This valve is engineered for precise, dynamic control of actuator position, velocity, and force in closed-loop and open-loop industrial applications.
