Product Overview
The Rexroth 4WRZE 10 W8-50-7X/6EG24N9ETK31/F1D3M (Material No. R901086547) is a pilot-operated, two-stage proportional directional valve from the proven 4WRZE series, designed for continuous, high-dynamic 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 position-controlled spool, delivering infinitely variable directional control proportional to the electrical command signal. With a nominal size of NG10 (size 10) and a rated flow of 50 L/min at a 10 bar valve pressure differential, this valve is engineered for precise velocity and position regulation of actuators in demanding closed-loop and open-loop applications. The integrated on-board electronics (OBE) with the “F1D3M” configuration provide factory-set, current-controlled solenoid drive with excellent repeatability, minimal hysteresis, and simplified commissioning via standardized command interfaces.
