Product Overview
The Rexroth 4WRZE 16 W8-100-73/6EG24N9K31/F1D3M (material number R901051826) is a pilot-operated, two-stage proportional directional valve from the Rexroth 4WRZE series, designed for continuous, high-dynamic control of flow direction and flow magnitude in industrial hydraulic systems. The valve combines a size 16 main stage with a proportional pilot stage, actuated by a single proportional solenoid with central electrical connection and integrated position feedback, enabling precise, stepless spool positioning proportional to the electrical command signal. With a nominal flow capacity of approximately 100 L/min at a 10 bar (Δp) valve pressure drop per land and a maximum operating pressure of 350 bar, this valve is engineered for demanding closed-loop and open-loop applications where accurate velocity, force, and position control of hydraulic actuators is required. The 4WRZE design provides excellent repeatability, low hysteresis, and fast response, making it a direct-fit replacement for OEM Rexroth proportional valve installations.
