MGM Series 217 Excess Flow Check Valves are designed for use where flanged connections are required. They are made completely of carbon and stainless steel and are machined from bar stock, not castings, for added durability.
The MGM Model 217 Excess Flow Check Valves are single flanged, wafer style valves designed to fit inside Schedule 160 tank nozzles or 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. Model 217 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 217 is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after repairs are made.
