Product Overview
The Rexroth 4WRZE16W8-100-74/6EG24N9EK31/F1D3M (material number R901042860) is a pilot-operated, two-stage proportional directional valve from the Rexroth WRZE 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 position-controlled spool feedback, enabling precise, load-independent metering of actuator motion. With an NG16 (size 16) main stage and a nominal flow capacity of 100 L/min at a 10 bar (145 psi) pressure differential per land, this valve is engineered for demanding motion-control loops where smooth acceleration, accurate velocity regulation, and repeatable positioning are essential. The integrated electrical position feedback of the main spool ensures high control accuracy and fast dynamic response, making the 4WRZE16W8-100-74/6EG24N9EK31/F1D3M a direct-fit replacement for OEM proportional valve installations in presses, injection molding machines, and heavy industrial automation equipment.
