SOLENOID DIRECTION CONTROL VALVES

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.While changing the coil it is not  necessary to open the pressure tight chamber. 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.

S.M.Shah & Co. offer Solenoid Direction Control valves with CETOP 3,5 & 8 size with spool centre conditions like open,closed,float & Tandem type.The basic function of directional valves is to start,stop & control the direction of fluid flow.
