About Us

The Eichler Excess Flow Valve (EFV) Available with or without auto bypass reset, is affordable and easy to install. The Eichler EFV is a Low Pressure EFV ideal for homes or businesses. This unique safety device installs in minutes within existing pipes. The Eichler EFV is available in various configurations to meet the needs of a wide range of distribution systems. Unlike similar offerings, it can be installed vertically or horizontally and is effectively accurate within 20 degrees of level.
The Eichler EFV fits snugly in the interior of the supply line prior to the gas meter. The flange securely holds the EVF in place. The EFV allows the specified flow of gas to pass through the valve allowing normal gas flow with very little to no pressure drop. When a substantial leak causes an excess flow of gas equal to the specified cutoff, the excess flow valve will close. When the repair is made to the line and returned to service the EFV will reset as the pressure is equalized.
