Flashback Arrestor - Stainless Steel Sintered Element | High Capacity Flame Protection, Reverse Flow Prevention, Temperature Sensitive Cut-off Valve

Flash back arrestors - for gas welding installations
Multiple safety features
Precision-engineered to eliminate every possibility of explosion of fire caused by a flashback
Available versions :
Protex RA / RO : Regulator mounted flashback arrestor Acetylene/Propane and Oxygen respectively
FR-18 : A pair of torch mounted flash back arrestors
FR-63 : Flashback arrestor for pipelines (Acetylene service)
Functions :
Puts out the flame
A high capacity Flame arresting element (Stainless Steel sintered element) effectively puts out the flame in case of full flashback. The filter capacity is large enough to ensure unobstructed flow of gas during normal operation.
Prevents reverse flow of gas
A non-return valve fitted next to the filter element closes when the build of reverse pressure is equal to or greater than the pressure of the normal flow. Normally kept open by the force of normal flow, it opens again when reverse pressure stops.
Cut off gas in case of flashback
A temperature sensitive cut-off valve cuts of gas before reaching ignition temperature in case of fire.
A pressure wave will activate a positive valve lock, which prevents gases flowing forward to the point of ignition.
In case of Protex RA/RO, following a flashback, the arrestor must be removed from the regulator or outlet point to reset by resetting the pop-up button.
If the temperature sensitive cut-off has been activated, the Flashback arrestor has to be replaced.
