Fike DFI™ Valve Technology – A Dust Safety Science Podcast

With the release of Fike’s DFI™ Explosion Isolation Flap Valve, and the “Are Flap Valves Safe” study, Fike team members have been busy working across the industry to highlight the safety considerations that need to be taken when addressing dual flap valve options. Listen to this podcast with Jim Vingerhoets, Global Explosion Protection Project Manager and Bruce McClelland, Explosion Protection Business Director speak with Chris Cloney of Dust Safety Science on the technology behind our newest explosion solution.

Fike DFI™ – A Flap Valve You Can Trust

Tested and Certified under Real-World Conditions – Was Yours?

Did you know a significant number of current ATEX-certified explosion isolation flap valves are…

  • Tested in setups not representative of actual industrial processes?
  • Certified for pressures for which they weren’t accurately tested?
  • Currently under review and may be de-rated or uncertified? ­­

Reliable Dual-Locking Mechanism – Proven to withstand pressure differentials and oscillations that “push and pull” on a closed flap, unlike other flap valves which failed identical flame isolation tests.

Wide Range of Protection Capabilities – Able to withstand high pressures associated with nearly all dust types: organic ST1 dusts (grain, coal, sugar, flour), organic ST2 dusts (chemical, pharmaceutical) and metal dusts (aluminum, iron, zinc and alloys).

Accessories and Variants – Valves come standard with electrical locked indicator and may be equipped with a dust layer sensor and automated air purge cleaning. Available in stainless steel execution for corrosion-sensitive and hygienic applications.

Flexible Installation – Available between 4- to 40-inches, with a small footprint, capable of being installed at horizontal and vertical orientations without bend restrictions, and closer to the vessel than other flap valves.
