- Wet-type DC explosion protection solenoid
- 90° rotatable explosion protection solenoid
- Pressure-tight chamber needs not to be opened when coil is to be replaced
Industrial Applications
- WE type explosion-proof valve is the directional valve of explosion protection solenoid used to control start, stop and flow direction of oil fluid.
- The directional control valves consist of housing(1), one or two solenoids(2), the control spool(3), and one or two return springs (4). In the de-energised condition the control spool(3) is held in the neutral or initial position by means of return springs(4) (except for pulse spools). The control spool (3) is actuated via wet pin solenoids (2).
- To guarantee satisfactory operation care should be taken to ensure that the solenoid pressure chamber is filled with oil.
- The control spool(3) is moved to the expected position by solenoid(2) and pushing rod(5), and
- this gives free-flow from P to Aand B to T or P to B and A to T.
- When the explosion protection solenoid(2) is powered off, control valve element (3) is pushed
- to the initial position by reset spring (4).
