Advantages of Highfield’s Emergency Gas Shut Off Valves
The spring-loaded internal plunger mechanism on our fusible gas meter shut off valves automatically activates when the ambient air temperature reaches 136° F. This causes the plunger to immediately close against the valve seat, preventing gas from feeding a fire and drastically reducing the amount of potential fire damage to your property. Effective sealing is achieved with metal-to-metal seat contact. Fire Valves are required by law in some states where gas meters are installed inside a residence or commercial facility.
