WE6  |  Data Sheet - Operation Manual 1/24 WK 420 970  |  01.2021 DATA SHEET - OPERATION MANUAL Directional spool valve electrically operated type WE6 NS 6  |  pmax 35 MPa  |  Qmax 80 dm3/min  |  WK 420 970 APPLICATION Directional spool valves type WE6… electrically operated are used to change direction of fluid flow in a hydraulic system which allows to change direction of movement of an actu- ator (usually a piston rod of a cylinder or a hydraulic motor) and to control functions: start and stop. These valves are used for subplate mounting in any position in a hydraulic system. The product is compliant with the directive 2014/35/UE. DESCRIPTION OF OPERATION Main elements of directional spool valve type WE6… : housing 1, solenoids 3, spool 2, centering springs 4 and manual override 5. The valve is shifted when spool 2 is moved into one of end positions by the force of solenoid 3. The return of the spool into neutral (de-energized) position is caused by the centering springs 4. The shape of the spool affects connections configuration of ports: A, B, P and T. Function of ports: P - supply port; T - oil return to the tank; A, B - ports for an actuator (a cylinder or a hydraulic motor). In case of emergency, the spool can be shifted manually by the override 5 - only for version with manual override option. Directional spool valve should be mounted in easily accessible way.
