Product Overview
The Rexroth 4WRZE 16 W8-150-74/6EG24N9EK31/F1D3M (Material Number R900757605) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series, size NG16 (nominal flow 150 L/min at Δp = 10 bar per land). It is designed to control both the direction and the magnitude of flow in industrial hydraulic systems by means of a proportional solenoid acting on a pilot spool, which in turn positions the main spool through hydraulic pilot pressure. The valve provides continuous, stepless control of actuator speed and direction, making it a core component in closed-loop and open-loop motion control architectures. The integrated on-board electronics (OBE) with the “F1D3M” configuration enable precise current-to-flow characteristics, while the spring-centered main spool ensures a defined fail-safe mid-position when de-energized. This valve is engineered for demanding industrial duty, offering high dynamic response, low hysteresis, and excellent repeatability.
