Flame Arresters
Flame Safety Valve (Flashback Arrestor)
A flame safety valve is a safety device in oxy-gas welding and cutting systems that prevents backflash flame and reverse gas flow from reaching hoses, regulators and cylinders. Its body contains a check valve to prevent reverse flow, a sintered stainless steel flame arrestor that extinguishes the flame, and a thermal valve that cuts off the gas in case of overheating.
For oxygen and fuel gases (acetylene, propane / LPG), separate models are supplied ready to be fitted to the regulator outlet or torch inlet.
