When selecting a thermal or electro-thermal shutoff, it is important to determine the correct valve material for the media you will be using, the correct size, the regulations and industry standards you need to conform to, the valve type (ball or butterfly), and end connections. Online configurators, such as the FM Fire-Safe Shutoff configurator makes it easy to select each of the assembly options that best fits your application.
However, it is equally important to select an assembly design that will prove durable in the field, and minimize the amount of field maintenance and repair required over time.
Assured Automation’s FM Fire-Safe Shutoff fusible link design provides many years of reliable service in the field.
FM Fire-Safe Thermal and Electro-Thermal Shutoff Emergency Block Valve Assemblies
The Assured Automation® 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. The heat actuated, FM & U.L. listed thermal links automatically shut off or open the valve at predetermined temperatures. A unique, removable handle allows the valve to be manually operated at any time without affecting the fusible links.
Assured Automation’s FM Fire-Safe Thermal and Electro-Thermal ball valve and butterfly valve assemblies are designed to spring a valve to a designated position (open or closed) during an upset condition such as fire. Valves are mounted with a spring canister and thermal link. The thermal link will melt at a predetermined temperature (165°F-500°F) and spring the valve to a chosen fail position.
The entire package is FM approved* and ensures your plant will meet all requirements involving thermal shutoff valves.
A handle is included with the assembly and allows the valve to be manually operated at any time without affecting the fusible link.
