Product Overview
The Rexroth 4WRZE 10 W9-85-73/6EG24N9ETK31/F1D3M (Material Number R901053128) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRZE series. It is designed to control the direction and magnitude of hydraulic flow in proportion to an electrical input signal, making it a core component in closed-loop and open-loop motion control systems. The valve utilizes a two-stage design in which a proportional pilot valve actuates the main spool of a high-flow directional valve, delivering precise, continuously variable flow control with minimal hysteresis and excellent repeatability. With integrated position feedback on the main stage, this valve is engineered for demanding industrial applications requiring accurate velocity, position, and force control of hydraulic actuators.
