Industrial Applications
- Directional valves of type WE5 are solenoid operated directional spool valves. They control the start, stop and direction of a fluid. This valve is widely used in various hydraulic systems and pilot valves of various pressure valves.
- These directional valves basically consist of the housing (1), one or two solenoids (2), the control spool (3), and one or two return springs(4).
- The control spool (3) is held by the return spring (4) in the central or in the initial position (except for detented spools). The control spool (3) is actuated via wet pin solenoids (2). In the energized condition. The force of the solenoid (2) acts via the plunger (5) on the control spool (3) and shifts the same from its rest position to the desired end position. Thus, the required flow pattern from P to A and B to T or P to B and A to T is selected. When the solenoid (2) is de-energized, the control spool (3) is returned to its neutral position by the return spring (4). A covered manual override is provided so that the control spool (3)can be operated without energizing the solenoid.
- Type 4WE5N 6.0B/O...
- This version is a directional valve with 2 switching positions and 2 solenoids without detent and springs. There is no defined switching position in the de-energized condition.
- Type 4WE5N 6.0B/OF..
- This version is a directional valve with 2 switching position, 2 solenoids and a detent. Thus, the relevant switching positions are fixed and continuous energization of the solenoid is not necessary.
