Product Overview
The Rexroth 4WRTE 10 (Material Number: R901325866) is a high-response, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Part of the renowned Rexroth 4WRTE series, this valve utilizes a two-stage design with a pilot valve and a main spool, actuated by a high-performance proportional solenoid. It features integrated position feedback via an inductive displacement transducer, enabling exceptional dynamic response and high repeatability. This valve is engineered to seamlessly interface with modern proportional amplifier cards, providing accurate, infinitely variable control of actuator speed and direction in open-loop or closed-loop applications.
