MGM Series 166 Excess Flow Check Valves are designed for use where flanged connections are required. They are made completely of carbon steel and/or stainless steel not castings, for added durability.

No. 166 MGM Excess Flow Check Valves are single flanged, wafer style valves designed to fit inside Schedule 80 pipe. The valve flange will fit inside the bolt pattern of 150# or 300# flanges. Standard gaskets should be used on both sides of the valve.

No. 166 MGM Excess Flow Check Valves can be mounted in any orientation with negligible effect on flow rate. Each valve will have the proper flow direction indicated by an arrow stenciled on the flange. As with all MGM excess flow check valves, the series 166 is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after repairs are made.
