Product Overview
The Rexroth 4WRZE 16 W9-150-74/6EG24N9ETK31/F1D3M (material number R901268442) 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 pilot stage with a proportional solenoid and a spring-centered main spool, allowing stepless, infinitely variable positioning of the main spool in proportion to the electrical command signal. With a size 16 (NG16) main stage and a nominal flow rating of 150 L/min at a 10 bar (1 MPa) pressure differential per land, this valve is engineered for precise velocity and position control of actuators in demanding closed-loop and open-loop applications. The integrated on-board electronics (OBE) with the “F1D3M” configuration provide factory-set, calibrated amplifier characteristics, enabling direct connection to a PLC or controller via a standard analog command signal without external amplifier cards.
