Replacement Diaphragm Membranes for Pulse Jet Valves
NBR, Viton (FKM) and EPDM diaphragm membranes precision-molded to fit ASCO, Goyen, DMF, SBFEC and compatible pulse jet valves. Airtight seal, chemical resistance, extended service life.
Diaphragm repair kits for common pulse valve brands, and a diaphragm being replaced on site.
Material Selection by Application
NBR (Nitrile)
General-purpose membrane for standard compressed air applications. Good oil resistance. Cost-effective for cement, steel and power plants with clean dry air supply.
Viton® (FKM)
Superior resistance to fuels, acids, solvents and high temperatures. Ideal for chemical plants, solvent dust, high-temperature compressed air lines. Longer service life than NBR.
EPDM
Excellent ozone and weather resistance. Good for outdoor valve installations and water-based environments. Used in food processing and outdoor baghouses.
