The valve is held open by a stretched wire containing a fusible link. When the temperature rises above 165° F, the link will melt and the tension of the internal spring closes.
The Model 110-G Fire Safety Gas Shutoff Valve is used in fuel gas piping systems to provide automatic shutoff of fuel gas flow in the event of a fire. Valve operation is fully mechanical and independent of the electrical power supply. The emergency fuel line shut-off is mandated by many codes. The Model 110-G may be used in any gas flow application by locating the valve in a horizontal pipe run where the gas supply enters the building. Install the trip wire with the fusible link located in the area to be monitored for excessive temperature. the valve.
Operation: The valve is held open by a stretched wire containing a fusible link. When the temperature rises above 165° F, the link will melt and the tension of the internal spring closes the valve.
Testing: As with any piece of safety equipment, the gas shutoff valve should be tested upon completion of installation and regularly thereafter to ensure that it will close in the event of excessive temperature at the fusible link. Ideally, the link would be heated with a small flame until the link melted. The valve should snap closed immediately. If the valve does not close properly, the wire should be checked for freedom of movement, and the mechanism of the valve should be checked for free operation.
