FUNCTIONAL DESCRIPTION
- Type WE directional control valves are solenoid operated spool
valves. They control the start, stop and direction of flow.
- Essentially the directional control valves consist of housing(1),
one or two solenoids(2), the control spool(3), and one or two
return spring(4).
- In the de-energised condition the control spool(3) is the held
neutral or initial position by means of return spring(4)(except for
impulse spool). The control spool (3) is operated by wet pin
solenoids(2).
- To guarantee satisfactory operation care should be taken to ensure
that the solenoid pressure chamber is filled with oil.
- The force of the solenoid(2) acts via the plunger (5) on the
control spool(3) and pushes this from its neutral position to the
required end position. This gives free flow from P to A and B to T
or P to B and A to T.
- When solenoid(2) is de-energised, the control spool (3) is returned
to its neutral position by means of return springs(4).
- An optional hand emergercy (6), allow movement of the control
spool(3) without energizing the solenoid.
- Type 4WE 6../OF…(impulse spool, only for symbol A,C and D)
This design incorporate directional control valves with 2 switching
positions, 2 solenoids and a detent. Both switching positions are
thus fixed altemately and there is no need to continually energise
the solenoid.
