HYDAC 4/2 directional spool valves 4WE 6 QA series are directional valves for oil hydraulic systems, which serve to open and close flow paths.
In the de-energised mode the control spool is held in the rest position by the return spring. The actuation of the control spool occurs via an oil immersed solenoid. The solenoid pushes the control spool from its rest position to its final position. This opens the required flow paths according to the symbol. When the solenoid is de-energised, the control spool is pushed back to the rest position by the return spring. A manual override permits the valve to be switched without energizing the solenoid.
