5-4WE Directional Spool Valves

The Bosch Rexroth 5-4WE is a series of high-performance, solenoid-actuated directional control valves commonly used in industrial hydraulic systems. These valves operate by using an electrically controlled spool within a housing to change the direction of fluid flow, which in turn controls the movement of a hydraulic cylinder or motor. When the solenoid is energized, it shifts the spool to open and close internal passages, connecting the pressure port (P) to one of the actuator ports (A or B), while simultaneously connecting the other actuator port to the tank port (T). Their primary function is to start, stop, and direct the flow of hydraulic fluid, enabling precise control over machine actuators and movements. These reliable 5/4-way valves are crucial components for automation, machine tool, and mobile equipment applications requiring four port connections and five possible spool positions.
