4WRDE Directional Control Valves

The Bosch Rexroth 4WRDE Directional Control Valves are high-performance, pilot-operated proportional spool valves. They incorporate an electrical position feedback system and integrated electronics (OBE), ensuring superior accuracy, high response sensitivity, and minimal hysteresis. The main valve spool is precisely controlled by a proportional pilot valve that receives an electrical command signal to adjust the spool's position. This operation accurately modulates the connection between system ports, controlling both the direction and magnitude of the fluid flow. The 4WRDE series is highly flexible and suitable for demanding closed-loop applications such as highly accurate position, velocity, force, and pressure control.
