Product Overview
The Rexroth 4WRTE-43-M-00 (Material Number: R901325866) is a high-response, pilot-operated proportional directional valve manufactured by Bosch Rexroth. Engineered for demanding closed-loop and open-loop control applications, this valve features a four-way, three-position (4/3) spool configuration with integrated position feedback for precise directional and flow control of hydraulic actuators. The 4WRTE series utilizes a high-response proportional solenoid with electrical position feedback on the main spool, enabling fast dynamic response, minimal hysteresis, and excellent repeatability. This valve serves as a critical control element in industrial hydraulic systems where accurate velocity, position, and force regulation of cylinders and motors is essential.
