4WRE Proportional Directional Valves

The Bosch Rexroth 4WRE proportional directional valves are high-response, pilot-operated valves used to precisely control the direction and magnitude of hydraulic fluid flow in a system. They operate using a proportional solenoid which translates an electrical input signal into a proportional mechanical force, shifting the main spool to regulate the flow area. This modulation allows for smooth and accurate control of actuator speed and position, offering dynamic performance in demanding applications. Their primary functions include speed control, force/pressure control, and precise positioning in industrial machinery and mobile equipment. These valves are essential for complex motion control tasks requiring variable flow characteristics based on an electrical command.
