MGM is pleased to announce its acquisition of a high flow excess flow check valve from Hemco Industries. These double flanged valves offer much higher flow rates than MGM’s other double flanged valves and are available in 2”, 3” and 4” versions. They are made of carbon and stainless steel.

The Hemco Excess Flow Check Valves are equipped with either 150# or 300# raised face, forged flanges. Standard gaskets should be used on each end.

The Hemco High Flow 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 High Flow Valve is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after the repairs are made.
