Aluminum Alloy Pulse Jet Valve OPTIPOW 135 4 Inch Clean Dry Compressed Air Black Pulse Valve

Closing
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.

Opening
When cleaning is initiated the solenoid valve closes the connection (a) and opens to ambient (b) which means that volume B is evacuated. The membrane is pressed upward (c) and the volume A is evacuated through the 2 ports at the outer side of the valve house.

The plunge is rapidly moving upwards by the pressure difference over the plunge.

The compressed air in the pressure tank is released through the pulse pipe as a pulse and further on to a row of filter bags.
