Model 50 MGM Back Pressure Check Valve
Application Overview
MGM Series 50 Back Pressure Check Valves are designed to allow flow in one direction only. They are made completely of carbon and stainless steel. Bodies are machined from bar stock, not joined in sections, for added durability. The metal seating allows slight leakage in the closed position.
The Model 50 MGM Back Pressure Check Valves are designed for installation in lines that flow into pressure tanks. They should be in inflowing lines when outward flow is never required. This model can be mounted in any orientation.
As with all MGM Back Pressure Check Valves, do not reduce outlet pipe size. Back Pressure Check Valves should be installed as close as possible to the container, with the stem pointed inwardly toward the container.
