Metaval is a leading supplier of flame arrestor in Australia. In simple terms, a flame arrester is a device that stops fire from passing through a gas line, preventing the risk of fire in industrial setting. This makes them an integral part of industrial safety controls. They are also often used as vacuum relief or tank protection valves.
Mechanically, a flame arrester is a passive device with no moving parts. Under normal conditions, it allows for the free flow of gas. But if fire tries to move through it, the machine will absorb the heat and stop the spread of the flame.
