DA-SB DETonATION FLAME ARRESTER

DA-SB explosion-proof back-fire relief valve of Finekay can prevent the flame from breakdown while the explosion and detonation happen. However, it cannot bear the long-time stable firing. The installation site of the explosion-proof back-fire relief valve should be far away from where the fire is easy to take place, such as gas evacuation pipeline. The explosion-proof back-fire relief valve can be designed as the single-directional or bi-directional one with the stable explosion or unstable explosion according to the actual working demands. If the long stable firing cannot be removed from the working conditions, the temperature sensor needs to be installed.
