Explosion Isolation Flap Valve, Explosion Proof Device, Passive Flap Style Isolation Valve for Dust Explosion

Passive flap style isolation valve-When a dust explosion begins to propagate down a pipeline the flap valve automatically closes from the pressure of the explosion. The flap valve remains shut and is designed to prevent any flame from further propagation. Unique to the AFV explosion isolation valve is a flap that is designed to stay open during normal operation. Typical flap valves rely on the flow of air in a pipe to lift up the flap. The AFV explosion isolation valve is able to offer lower pressure drops across the valve compared to other valves by featuring a normally open flap. Additional features include an integrated sensor to signal when the flap is shut, a variety of sizes to fit any application, and is available in both stainless or carbon steel designs.
