4WRSE High Response Control Valves

The Bosch Rexroth 4WRSE High Response Control Valves are direct-operated, proportional directional valves designed for applications requiring extremely high dynamics and precision control. These compact units are characterized by their integrated control electronics (OBE) and electrical position feedback, which ensure the flow rate is continuously and accurately proportional to the electrical command signal. The valve works by having its control spool directly actuated by solenoids, with the spool's actual position being monitored for closed-loop control by the integrated electronics. Their main function is the high-dynamic, continuous control of a hydraulic flow's direction and magnitude, making them ideal for precise position and velocity control loops. The 4WRSE series is available in sizes 6 and 10 and is rated for a high maximum operating pressure of 315 bar.
