Product Overview
The Rexroth 4WRZE 10 W8-50-73/6EG24N9ETK31/F1D3M (Material Number: R901108547) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth WRZE series. Engineered for precise control of flow direction and magnitude in demanding hydraulic systems, this valve utilizes a proportional solenoid on the pilot stage to infinitely adjust the main spool position. This results in a smooth, continuous, and highly accurate control of actuator speed and force, making it an ideal choice for closed-loop position, velocity, and pressure control applications in modern industrial machinery.
