MGM Excess Flow Check Valves (EFCVs) are spring loaded check valves. When properly sized and installed, they are designed to close and shut off flow of fluid from a source when the rated flow capacity is exceeded.

Each valve is clearly marked with the shut off flow rating, which is stenciled into the outside diameter of the mounting flanges. To operate properly, EFCVs must be correctly sized for each specific application. The valve must also be installed correctly to offer the proper protection.
