oxyhydrogen torch has installed a flashback arrestor in the front of valve. If there is any back-fire when closing the valve, the flashback arrestor will stop back-fire entering into the valve automatically. So the flashback arrestor will flame out automatically because of no gas.The flame won't reach to the valve forever and sealing ring will get the efficient protection.
The flashback arrestor, which is installed in the gas out end of valve, can keep from backfire and protect the sealing ring of valve when there is any back-fire. Therefore it can extend the service life of valve sealing ring.
