PULSE JET TYPE DUST COLLECTOR VALVE

Pulse jet valves are indirect operated solenoid valves especially designed for dust collector systems. When the solenoid is energized, trapped air above a diaphragm is quickly exhausted causing a high pressure difference across the diaphragm. Thereby the diaphragm is suddenly opened. When the solenoid is de-energized, air escapes through a hole to the chamber above the diaphragm which balances the pressure and instantly closes the valve. Pulse jet valves are used in filtering systems of dust collectors, gas turbines, and desulfurization equipment. They are commonly used to clean filters such as cartridge filters, envelope filters, ceramic filters, and sintered metal fiber filters. The fast opening and closing of the valve is of great importance for effective cleaning of filters and economical consumption of compressed air. This is made possible by keeping the weight of the moving parts small and therefore having a small inertia.
