Thermal Safety Shut-Off Valves
The 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 degrees F-500 degrees F) and spring the valve to a chosen fail position.The FireChek is a heat-actuated emergency shutoff for gas and flammable liquid equipment. The FireChek safety mechanism is used in air lines on control valves with pneumatic actuators to provide emergency shutdown in case of fire.Thermally activated Emergency Isolation Valves (EIVs) are critical components in refinery, terminal and distribution safety systems. Thermal activated shutoffs work like fuses in the piping that carry extracted fuels. When a fire occurs, the fuel flow is shut down, preventing the fuel from feeding the fire.
