Function and configuration

Explosion - Proof Hydraulic Control Valve , Solenoid Directional Control Valve

GWE type directional control 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-energized 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 A and 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).

 

Type GWE 10 . L3X / O B2...

(Limited to valve element A, C and D)

This type is dual explosion-resistant solenoid 2-position directional valve without a locating mechanism, one of explosion protection solenoids must be powered on in any position, it has not a specific switching position under power-off position.

 

Type GWE 10 . L3X / OF B2...

(Limited to valve element A, C and D)

This type is dual explosion-resistant solenoid 2-position directional valve with a locator, the valve element can be held at any position and it is unnecessary to continuously electrify the solenoid.

 

Cartridge throttle

The cartridge throttle is necessary since actual flow may be larger than the performance limits of the valve during switching process.

This cartridge throttle is inserted in the P channel of the directional control valve.
