Fike►Products►Explosion Protection►Isolation►DFI – Dual-Flap Isolation Valve DFI – Dual-Flap Isolation Valve A Flap Valve You Can Trust Unlike many other flap valves, with Fike DFI™ you’ll find no design shortcuts. No inferior parts or materials. No inaccurate testing and certifications. Just an ultra-reliable, compact passive explosion isolation valve that’s tested and proven to perform accurately under pressures which it may experience during a deflagration. REQUEST A QUOTE PRODUCT DETAIL Currently available in sizes up to DN800 (32 inches), Fike DFI™ reliably isolates pressure and flames from interconnected equipment with the following important advantages: Proven Safe Experiments have proven that testing standard EN16447 does not accurately represent real-world conditions. Therefore, this standard is currently under review, and many flap valves certified under this standard may fail to safely isolate deflagrations from interconnected pipes and vessels. Testing methods for Fike DFI not only meet EN16447’s requirements but exceed it by: Including a protected zone pipeline with additional dust injectors Holding flaps in an open position until the precise time of ignition or flow reversal Using explosion vent panels instead of open venting ports Using fans with real process flow and turbulence levels This means you can trust that Fike DFI has been tested under all real-world applications’ conditions and variables, including those found in your unique process. Flexible Installation Fike DFI avoids the need for any pipeline rework because it can be installed in nearly all geometries and orientations, and is: Engineered to perform in both horizontal and vertical pipes and close to bends Able to be installed closer to a vessel than other flap valves due to its fast-closing, lightweight flaps Compact in its design with a reduced footprint using two smaller flaps instead of one large flap Available in sizes up to DN800 (32 inches) Wide Application Range Suitable for nearly every application, Fike DFI is the ideal standard flap valve that protects against nearly all industries and applications under real-world conditions: high explosion pressures up to 1.5 barg ST1 dusts (sugar, powdered milk, charcoal, sulfur, zinc, etc.) ST2 dusts (wood, flour, etc.) light metal dusts (aluminum) low MIE (minimum ignition energy) dusts If you have questions about DFI, explosion isolation, your current explosion flap valve or testing standard EN16447, or if you are ready to protect your process with DFI, contact a Fike explosion protection expert today!
