MGM Model 514 Excess Flow Check Valves are designed for use where flanged connections are required. They are made completely of carbon and stainless steel.

Model 514 Excess Flow Check Valves are double flanged and are equipped with either 150# or 300# raised face, forged flanges. Standard gaskets should be used on each end.

Model 514 MGM Excess Flow Check Valves can be installed in any orientation with negligible effect on flow rate. Each valve will have the proper closing flow direction indicated by an arrow stamped into the body. As with all MGM excess flow check valves, the Model 514 is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after the repairs are made.
