The IEP IFV-M passive isolation flap valve is designed for general combustible dust explosion propagation.
Isolation of a deflagration is critical and the means to do so are detailed in NFPA 69. Protection of facilities and equipment that are exhausted by air-material separators (Dust Collectors) and other process equipment handling combustible dusts requires an active isolation system or a passive isolation flap valve like the IEP Model IFV-M. The passive explosion isolation valve is self-actuating, providing a mechanical barrier to prevent the propagation of flame and burning materials to upstream equipment. The IFV-M passive isolation valve features an accumulation sensor, closure sensor, and Interface Module.
IFV-M diameter sizes range from 4″ to 40″. All Isolation valves include a flap sensor, accumulation sensor, and flap lock.
