FM Fire-Safe Series
Thermal Shut-Off Valves

Assured Automation's FM Fire-Safe Thermal and Electro-Thermal ball valve and butterfly valve assemblies are designed to shut off automatically and control hazardous conditions. The ball valve and butterfly valve assemblies are Factory Mutual (FM) approved per use in flammable liquid application per FM class 7440. The heat actuated, FM & U.L. listed thermal links automatically shut off or open the valve at predetermined temperatures. All valves come with a removable handle. The ball valves have the ability to use this handle to operate the valve manually at any time without affecting the fusible links or removing the spring loaded canister. The Butterfly valves require that the spring-loaded canister is removed for manual operation.
