The OPW 178S Series External AST ShutOff Valve is designed to shut off product flow from an aboveground storage tank, bulk loading rack or any place in the fuel supply line in the event of a fire. The 178S installs inline on fuel supply piping. A fusible link attached to a springoperated lever holds the poppet normally open. In the event of a fire, the fusible link melts at 160°F, allowing the springactuated poppet to shut off the flow of product in the fuel supply line. The 178S is available in 2″ female NPT connections.
