Product Overview
The Rexroth 4WRZE 10W6-50-73/6EG24N9ETK31/F1D3M (material number R901006547) is a pilot-operated, two-stage proportional directional valve from the Rexroth 4WRZE series, designed for continuous, high-resolution control of flow direction and flow magnitude in industrial hydraulic systems. The valve combines a pilot stage equipped with a proportional solenoid and a main stage with a position-controlled spool, enabling precise, load-independent metering of actuator motion. With a size 10 (NG10) main stage and a nominal flow capacity of 50 L/min at a 73 bar pressure drop per land, this valve is engineered for demanding motion-control loops where smooth acceleration, accurate velocity regulation, and repeatable positioning are essential. As a proportional directional valve, it interfaces directly with Rexroth or third-party proportional amplifiers, converting an analog current command into a proportional spool stroke and thus into a proportional output flow.
