MGM Model 302 Back Pressure Check Valves allow flow in one direction only and 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 302 Back Pressure Check Valves have male pipe thread on the bottom end. The valve 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 into the body. 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 poppet stem pointed inwardly toward the container.
