TECHNICAL SPECIFICATIONS:

Check valve, Flashback Arrestor safety device
Compliance with EN ISO 5175-1 (APRAGAZ)

The spring in the flashback arrestor does not allow the reverse flow of gas by exerting
continuous gas pressure. So, it prevents mixing gases in the hose and gaining an explosive
property of gases at low and high pressures.
The gas flow pressure lifts the valve spring on the valve to open the valve and allow the gas to
flow towards the cutting torch.
The special flame-trap filter by made of sintered chrome-nickel in the safety valve keeps flaming
backlash from the cutting torch.
