Excess Flow Valves
Make installation of excess-flow valves as easy as Perfection: We incorporate EFVs directly into Perfection products such as our Permasert couplings and PermaLock tapping tees to help you ensure safe, effective gas delivery.

Overview
Perfection EFVs prevents catastrophic leakage by tripping automatically: When gas flow reaches a critical rate, the force on a ball exceeds the opposing force on a spring, which causes the ball to seal against a seat. Reset is also automatic: Once downstream damage is corrected, a bleed-by or bypass flow of gas lets upstream and downstream pressures equalize, resetting the valve to its open position. (A full-shut-off EFV is also available, which must be reset manually.)
