Service Details:

SOLENOID DIRECTION CONTROL VALVES: DSG01,03,04,06 Single/Double solenoid. The direction control valves consists of housing,one or teo solenoids,the control spool & one or two return springs.In the deenergised condition the control spool is held in neutral or initial position by means of return springs.The control spool is operated by wet pin solenoids.The force of solenoid acts via the plunger on the control spool and pushes this from its neutral position to the required end position.This gives free flow from P to A or B & A to T.When solenoid is de-energised the control spool is returned to its neutral position by means of return springs.To guarantee satisfactory operation care should be taken that the solenoid pressure chamber is filled with oil.Solenoid operated direction valves control the start – stop & direction of flow.They are also used as pilot valves to operate other valves and so on.
