Bi-Torq® Valve Automation's fusible link shut-off valve has received Factory Mutual (FM) approval. These assemblies prevent the spread of fire by containing flammable liquids or gasses once the API 607 (American Petroleum Institute) fire-safe certified valve automatically closes based on thermal release of a fusible link.

FM approval means that Bi-Torq® Valve Automation fire safe fusible link valve assemblies can help reduce insurance costs and allow factories to meet facility-wide safety certifications. With torque outputs ranging from 55 to 21,000, FM-approved fusible link assemblies can be used with fire safe ball or butterfly valves from 1/2in through 24in line sizes.

Bi-Torq®Valve Automation's unique design allows for manual operation of most units even when the unit is armed, reducing the need for secondary valves. API 607 fire safe approved valves can be customer-specified or provided by Bi-Torq® Valve Automation in carbon or stainless steel construction with NPT, socket weld or 150# ANSI flanged end connections.

With valve seat choices in TFE®, RTFE®, TFM, PEEK and Delrin, Bi-Torq® Valve Automation's fire safe valves are suitable for a wide variety of industries. Applications for these automatic shut-off assemblies include tank farms, petrochem, airport and truck refueling stations, paint and toxic chemicals, and biofuel operations.
