DC24V 3 Inch Dust Collector Valve
Qingdao Star Machine’s high-quality DC24V 3 inch Dust Collector Valve in the dust removal system of the pulse bag filter plays the role of an air compressor switch. Through the output signal control of the pulse jet control equipment, the valve can clean the dust bit by bit into the filter bag within the set range to maintain the dust resistance of the filter room, so as to ensure the effectiveness of the function and the dust removal of the filter room.

Closing the Valve
The solenoid is closed to ambient and opened to the pilot air.
The pilot membrane is pressed down towards the seat.
Via the slot between the plunge and the house the pressure above the plunge will be equalised to the tank pressure and the plunge moves down to the pulse pipe and ends the cleaning pulse.
The time for a sequence (start opening to closed valve) is to some extent depending on process requirements but generally it is in the range of 100– 200 msec.
PILOT AIR CONNECTION
The pilot air for the solenoid is taken from the incoming tube to the pressure tank. The pipe for the pilot air is common for all valves in one tank and is connected upstream the main on- off valve of respective tank.
The pipe should have an on-off valve and a non-return valve which ensures that pressure is kept also if pressure decreases during pulsing.
Note: If a separate feeding pipe for the pilot
air is used the pressure for the pilot air should be approx equal to pressure in tank.
A too high pressure will give a remaining deformation to the membrane, which will reduce the lifetime and have a reducing effect on the function of the pulse cleaning.
