This 1/2 inch OD flare x 1/2 inch MIP SmartSense (TM) excess flow valve and thermal shut off is used with Dormont gas appliance connectors. SmartSense is an intricately-designed valve comprised of two primary components, a gas flow-limiting plunger and thermal shutoff sensing ring. In the event of a gas line rupture, disconnection, or even a fire, SmartSense detects the potential threat and automatically activates to ensure safety. The plunger limits gas flow in the event of a full-line rupture or disconnect, providing protection against excessive gas leaks. Once the gas line is restored and the pressure equalizes, SmartSense will automatically reset to provide the standard rate of flow. The internal thermal ring expands to stop gas flow when exposed to extreme temperatures ranging from 350 to 425 degrees F. It is approved and design-certified by CSA for use with natural, manufactured, mixed liquefied petroleum gases, and LP gas-air mixtures. Item comes in a bag.
