MGM Series 301 Excess Flow Check Valves are designed for use in threaded tank nozzles. They are made completely of carbon and stainless steel. Smaller valve bodies are machined from bar stock, the larger valve bodies from pipe and flat plate.
The Model 301 MGM Excess Flow Check Valves has male pipe threads on the bottom ends; they are equipped with a 1/4 inch notch in the threaded end to ease installation. The 301 MGM Excess Flow Check Valves can be mounted in any orientation with negligible effect on flow rate.
As with all MGM excess flow check valves models, the Series 301 is equipped with an orifice in the check mechanism to allow for pressure equalization and will reopen automatically after repairs are made.
All Size Values are in Inches.
