Product Overview
The Rexroth 4WRZE 10 E85-73/6EG24N9ETK31/A1D3M (material number R900617676) is a pilot-operated, two-stage proportional directional valve from the proven Rexroth 4WRZE series. It is designed to control the direction and magnitude of flow in hydraulic systems proportionally to the electrical input signal supplied to the integrated proportional solenoids. The valve utilizes a high-performance pilot stage with a position-controlled main spool, delivering precise, repeatable metering of flow for demanding motion-control applications. With a size 10 (NG10) main stage and an 85 L/min nominal flow rating at a 73 bar pressure differential, this valve is engineered for smooth, high-resolution actuation in industrial hydraulic circuits where accurate velocity and position control are critical.
