MGM Model 301 Excess Flow Check Valves are designed for use in threaded tank nozzles. They are made completely of carbon and stainless steel. Bodies are machined from bar stock, not castings, for added durability.

Model 301 Excess Flow Check Valve has male pipe thread on the bottom end. The valve can be mounted in any orientation with negligible effect on flow rate. As with all MGM excess flow check valves, Model 301 is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after repairs are made.
