Liquid Product - End of Line Detonation Flame Arrester approved as Foot Valve
Foot Valve – End of Line Liquid Product Detonation Flame Arrester Approved to EN ISO 16852
Deflagration = Explosion propagating at subsonic velocity
Detonation = Explosion propagating at supersonic velocity and characterized by a shock wave.
Flame propagation is stopped through used liquid.
Foot valve flame arrester prevents light-back at deflagration and stable detonation of potentially explosive vapor-air, and or gas-air mixtures in a pipe that is located upstream of the ignition source.
Liquid Product – End of Line Detonation Flame Arrester – Foot Valve: Explanation
Foot valve flame arrester is installed inside the storage tank at end of suction line. Foot valve flame arrester has two functions. At first, the tank is protected in case of flame propagation from pump side to the tank through the liquid in the strainer and second the liquid column is preserved by the integrated check valve.
