Excess Flow Valve

An Excess Flow Valve or EFV is a device that automatically restricts the flow of natural gas if an underground pipe is broken. It is installed on the service line that runs underground between the natural gas main and the meter on your property. If a service line becomes damaged causing a sudden and major pressure drop or gas leak, the EFV will automatically shut off the flow of natural gas.  In doing so, the EFV can prevent natural gas buildup and reduce the chances of a natural gas fire, explosion, property damage and/or personal injury.
