s that are built into the hose fittings. the non-return valves allow that gas to flow in one direction only. this prevents the gas from flowing back into a hose, forming a potentially explosive gas mixture. the risk of a hose explosion when lighting the torch due to gas flowing back is eliminated. bv 12 has a low weight and does not impede the work with the gas welding and/or gas cutting torch. the pressure drop in the non-return valve is insignificant. bv 12 can be used with up to 16 bar and in the temperature range -30°c to 50°c. the non-return valve is marked with gas type, through-flow direction, maximum working pressure and manufacturer. according to the swedish work environment authority's regulation regarding fusion-welding and thermal cutting, afs 1992:9 "when performing welding and cutting, welding torches must have a non- return valve between the welding handle and the hose for both fuel gas and oxygen". as the non-return valve is part of the safety equipment, aga recom- mends that it is checked at least every six months. the non-return valve does not replace the flashback arrestor. note! non-return valve bv 12. accessories. safety. accessories 1 = open 2 = closed 1 2
