DB18 DB18/G Diaphragm For Mecair Pulse Valve VNP206 VNP306 VNP408
DB18 ( DB18/G ) Diaphragm ( Membrane ) for Mecair pulse valve VNP208, VEM208, VNP308, VEM308, VNP408, VEM408; NBR material is standard, working temperature range is -5 to +80 ℃; Viton material is optional, for high temperature, working temperature range is -10 to +120 ℃. On a pulse jet baghouse pulse valves (also called diaphragm valves) control the release of air pulses during the cleaning cycle. When the baghouse control board or timer board initiates a cleaning cycle it sends an electrical signal to the solenoids, when then activate the pulse valve. Inside the pulse valve, a rubber diaphragm opens and closes to release the compressed air stored in the air header tank. The air then passes through the valve into the blow pipes above the filters and then is directed down into the filters to clean them.
