A valve which works on a thermostatic principle to stop and extinguish backfire in gas-air pipelines by utilizing the heat generated by the fire to actuate the mechanism which closes the valve. It also contains a swing check on the inlet connection which closes immediately upon shock caused by backfire, shutting off the gas-air mixture. It is designed for installation in a pipeline to feed gas-air mixtures to burners and the like.
