A pulse jet solenoid valve releases a short, high-pressure compressed-air burst to clean the filter bags in a baghouse dust collector. To choose one, match the valve port and flow coefficient (Cv) to your pulse pipe and air volume, pick an aluminum or brass body for the gas and environment, and confirm the working pressure and coil voltage (DC24V or AC110/220V). A right-angle (embedded) type fits most baghouses; a straight-through type is used where piping space allows.
What Is a Pulse Jet Solenoid Valve?
A pulse jet solenoid valve is an electrically controlled valve used in baghouse dust collectors and other pulse-jet cleaning systems. When the controller sends a signal, the valve opens briefly and admits a burst of compressed air into the blow pipe. The air expands through the nozzles, shaking the dust cake off the filter bags.
Key Selection Parameters
Match the port size to the blow pipe diameter, confirm the working pressure and coil voltage, choose an aluminum or brass body, size the flow coefficient (Cv) for the air volume, and verify the diaphragm material and connection type for your media and environment.
How Many Bags Per Valve
One valve typically serves one cleaning row, with the blow pipe and nozzles sized for that row. Provide your bag count, bag diameter and length, and the pulse pressure so the manufacturer can recommend the correct port and Cv.

Ningbo Kailing Pneumatic (KLQD), a manufacturer since 2003, supplies pulse jet solenoid valves with custom port sizes, coil voltages and diaphragm materials for OEM and baghouse projects.
Frequently Asked Questions
- FAQ How many filter bags can one pulse valve clean?
A common rule is one valve per cleaning row of bags, with the pulse pipe sized accordingly. Size the valve's Cv to the total air volume it must deliver to that row, and confirm with the manufacturer using your bag count and dimensions. - FAQ What working pressure do I need?
Most pulse jet systems run within a typical operating range. Too low a pressure will not remove the dust cake; too high can damage bags or increase air consumption. Start at the manufacturer's recommended range and adjust based on the measured differential pressure. - FAQ How often should I replace the diaphragm?
Diaphragm life varies with cycle frequency, temperature and media. Inspect it for cracks and wear during routine maintenance and keep spares on hand. Confirm the exact replacement interval with the manufacturer.
