Part Description: Check valves are used in main/reserve and selector valve systems. On main/reserve systems, the check valve prevents pressurization of the reserve system manifold by blocking the flow of INERGEN® agent from the main system to the reserve system. The check valve allows gas flow from the reserve (if actuated) to pass through into the distribution piping. On selector valve systems, check valves separate the actuation of smaller system(s) from the largest ones. The check valves are available in sizes from 1/2 in. through 3 in. Two body styles are available: weld neck flange and threaded flange.
