Frequently used by the chemical, petrochemical /, aviation and other industries, these valves are installed in locations where there is a possibility of a fire spreading from one storage tank to another. They help contain the damage to a local area by eliminating a potential source of fuel for the fire to spread. Once the fusible link is activated and released by the surrounding heat, the disc will close creating a piping element that provides failsafe protection in case of a fire. Tested and certified to API 6FD - Specification for Fire Test for Check Valves.
