Product Details
DG4V3 DG4V5 series Vickers solenoid valves control operated directional
Features:
Vickers DG4V directional control valve
maximum pressure(Mpa) 31.5
maximum flow(l/min) 14 35 63
Electrical operated directional control valve can directly control the flow on-off and change. It also can be used as the pilot-operated valve,which coulf operate other valves.
Functional description, section
Essentially 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 spoof (3)is held in
the neutral or initial position by means of return springs (4) (except for impulse spools).The control spool (3) is actuated via wet pin solenoids (2).
The force of the solenoids (2)acts via the plunger (5)on the control spool (3)and pushes this from its neutral position to the required end position. This gives free--flow from P to A and B to T or P to B and A to T.
When solenoid (2) is de-energized, the control spool (3) is returned to its neutral position by means of the
return springs (4). An optional hand override (6),allows movement of the control spool (3)without energising the solenoid.
