Product Overview
The Rexroth 4WRZE 25 W9-220-73/6EG24N9EK31/A1D3M (Material Number R900750197) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series. It is designed to control the direction and magnitude of flow in industrial hydraulic systems through continuously variable electrical input signals. The valve features a 4-way, 3-position spool configuration with integrated position feedback, enabling precise proportional control of actuator speed and direction. With a nominal flow capacity of 220 L/min at the specified pressure differential, this valve is engineered for demanding applications requiring smooth, accurate motion control and high dynamic response.
