Product Overview
The Rexroth 4WRZE25W6-220-73/6EG24N9EK31/F1D3M (Material Number R901040909) is a high-performance, pilot-operated proportional directional valve from the Rexroth WRZE series. It is engineered to control both the direction and magnitude of hydraulic flow in proportion to an electrical input signal, enabling precise, infinitely variable speed and position control of actuators in demanding industrial systems. The valve features a size 25 (NG25) main stage with a nominal flow capacity of 220 L/min at a 10 bar (145 psi) pressure differential per land, and is actuated by a proportional solenoid with integrated position feedback for closed-loop accuracy. Designated by the “W6” spool code, it provides a specific metering characteristic suited to regulated flow applications. The “6EG24N9EK31” solenoid configuration denotes a 24 V DC proportional solenoid with a central electrical connector and an integrated enable function, while the “F1D3M” suffix indicates the specific seal and adjustment variant. This valve is a direct-fit, OEM-compatible component designed for integration into sophisticated electro-hydraulic control systems.
