Brasscraft Mfg. Co. has continued its legacy of innovation with an enhanced version of its patented Safety+Plus Excess Flow Valve (EFV). The new Thermal Excess Flow Valve (TEFV) not only maintains the properties of the EFV but adds further protection against gas-related fires and explosions that provides even more protection for home and family.
In the event of a catastrophic rupture or disconnect, unrestricted gas flow forces the diaphragm to firmly position itself against the seat. This immediate action restricts gas flow to help avert a hazardous build-up of gas. The thermal excess flow valve utilizes a thermal ring that will stop gas flow through the valve when it is exposed to temperatures of 400 degrees Fahrenheit or greater. The valve is available at The Home Depot stores.
