Directional valves of type WE are solenoid-actuated directional spool valves. They control the start, stop and direction of a flow.
The directional valves basically consist of the housing (1), one or two solenoids (2), the control spool (3), and one or two return springs (4). In the de-energized condition, control spool (3) is held in the central position or in the initial position by the return springs (4). The control spool (3) is actuated by wet-pin solenoids (2).
To ensure proper functioning, make sure that the pressure chamber of the solenoid is filled with oil!
The force of the solenoid (2) acts via the plunger (5) on the control spool (3) and pushes the latter from its rest position to the required end position. In this way, the required direction of flow according to the symbol is released. After de-excitation of the solenoid (2), the return spring (4) pushes the control spool (3) back to its rest position.
The manual override (6) allows control spool (3) to be moved without solenoid energization.
