The safe delivery of gas remains a primary mission of the worldwide natural gas industry. To help accomplish this fundamental task, more and more utilities are taking safeguards to minimize occurrences of blowing gas due to pipe line breaks caused by third party damage and natural disasters. And the easiest, most dependable, and economical way is with an EFV excess flow valve from Perfection.

Powell Flow Limiters, marketed by Perfection, and other excess flow valves are incorporated into our Permasert® couplings and other gas distribution products... making the installation of an EFV as easy as installing these Perfection products. These self-actuating valves automatically close when gas flow exceeds a predetermined rate.
