DFI explosion isolation flap valve is now available in stainless steel assemblies for sizes 4 inches to 32 inches. Fike has also expanded its sizes of DFI up to 40 inches to meet the needs of larger dust collectors or other industrial applications that horizontally convey organic dust. The latest stainless-steel execution is safe for use within food production and chemical plants to protect against rust, paint or other contaminants entering the product. DFI includes two flaps on a vertical center-bar hinge which are held open by normal process flow. When a deflagration occurs, the pressure reverses the flow and quickly closes the lightweight flaps into a locked position strong enough to contain the pressure and flames and protect upstream equipment. DFI is considered a “passive” explosion isolation valve because it is activated by the pressure itself and not activated with electronics.
