FLAHBACK ARRESTORS

The spring in the flashback arrestor does not allow the backflow of gas by exerting continuous pressure. So it prevents mixing in the hose and gaining an explosive property of gasses at low and high pressures.

The flow pressure of gas releasesthe spring pressure exerted on to the valve and so a continuous gas flow is ensured into the torch. The special flame backfire guard in the flashback arrestor is made of sintered chrome-nickel and retains the backflame from the torch.

Thermic valve in the 1030, 1130 and 1231 begins when the flame goes into the valve and it extinguishes the flame by blocking the gas flow completely.

Thermic Valve: It keeps the gas passage open by means of a pin soldered in the bed under spring load. When the temperature around the filer reaches 100?C, in case of a gas backfire, the solder fuses and the pin blocks the gas flow by releasing it self from its bed. From the moment on the backfire protection valve is no more useful.
