Function and configuration

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 G4WE6...L6X/OB2...

(limited to functions A, C and D).

This type contains 2 switching positions and 2 directional control valves without locating mechanism explosion protection solenoid.

 

Type G4WE6...L6X/OFB2... pulse valve

(limited to functions A, C and D).

It contains 2 switching positions, 2 explosion protection solenoids and 1 directional control valve with locating mechanism. 2 switching positions are fixed separately, so it is unnecessary to continuously electrify explosion protection solenoid.

Cartridge throttle

The cartridge throttle is necessary since the 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.
