4WE6
The directional valves of type WE are solenoid-actuated directional spool valves that can be used as electro-magnetic component. They control start, stop and direction of a flow. The directional valves basically consist of the housing, one or two electronic solenoids, the control spool, and the return springs.
Product Description
In the de-energized condition, the control spool is held in the central position or in the initial position by the return springs (except for version “O”).If the wet-pin electronic solenoid is supplied with power, the control spool moves out of its rest position into the required end position. In this way, the required direction of flow according to the selected symbol is released. After the electronic solenoid has been switched off, the control spool is pushed back into its central position or into its initial position (except for valves with “OF” detent and valves without type “O” spring).A manual override allows for the manual switching of the valve without solenoid energization.
For unobjectionable functioning, the hydraulic system has to be bled properly. Without spring return “O” (only possible with symbols A, C and D)This version is a directional valve with two spool positions and two electronic solenoids without detent. The valve without spring return at the control spool has no defined basic position in the de-energized condition. Without spring return with “OF” detent (only possible with symbols A, C and D)This version is a directional valve with two spool positions and two electronic solenoids with detent.
The detents are used to fix the control spool in the relevant spool position. During operation, continuous application of current to the electronic solenoid can thus be omitted which contributes to energy-efficient operation.
