End of Line Deflagration Flame Arrester and Pressure Vacuum Valve approved to EN ISO 16852
Deflagration = Explosion propagating at subsonic velocity
Pressure/vacuum valve:
- Prevents escape of vapors
- Contamination of stored medium
- Displacement of vapors
- Environmental protection
- Limits the storage tank pressure
The pressure/vacuum valve approved as end of line deflagration flame arrester installed at end of vent pipes prevents light-back at deflagration of potentially explosive vapor-air, and or gas-air mixtures from outside (atmospheric conditions) to the protected side (e. g. storage tank).
