Product Description:
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.
Applications:
Industrial Dust Baghouse Systems
Purpose: Control compressed air pulse jetting to remove accumulated dust on filter bags.
Industry Applications:
- Cement Plant: Dust collector at the kiln end (smoke temperature < 80°C).
- Steel Plant: Dedusting at the sintering machine head (requires pre-cooler).
- Wood Processing: Sawdust collection system.
Powder Pneumatic Conveying Declogging
Install pulse valves at pipeline blockage points, triggering instant air flow impact to clear blockages (e.g. food-grade calcium carbonate, plastic granules conveying).
Materials Bunker Arch Breaking Device
Break material bridging in coal powder silos/grain bins (operating frequency: ≤ 30 times/minute).
