The 200 Series Excess Flow Check Valves are designed for use where flanged connections are required. They are made completely of carbon and/or stainless steel not castings for added durability.
The Model 200 MGM 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 200 MGM Excess Flow Check Valves can be installed in any orientation with negligible effect on flow rate. Each valve has the proper flow direction indicated by an arrow stamped into the body.
As with all MGM excess flow check valves, the Series 200 is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after repairs are made.
