4WRBKE OBE Valves

The Bosch Rexroth 4WRBKE Proportional Directional Control Valves are high-performance, pilot-operated units with on-board electronics (OBE) and an inductive position transducer. Their function is to provide highly accurate, proportional control over the start, stop, and direction of fluid flow in demanding hydraulic applications. They work by using the OBE to precisely position the main stage orifice spool based on an electrical command signal, providing a controlled flow characteristic. These valves feature electronic overlap compensation and calibration to ensure minimal hysteresis and highly dynamic performance. Available in nominal sizes 10 to 35, they are designed for maximum working pressures up to 350 bar, offering robust and flexible control for motion and speed regulation.
