MGM Model 167 Back Pressure Check Valves are designed to allow flow in one direction only. The check mechanism is held in the closed position by a spring, which stops flow in the reverse direction. When pressure from flow in the permitted direction overcomes the force of the spring, the check mechanism opens. When this flow stops or reverses, the check closes. The metal-to-metal seating allows slight leakage after closure. The valves are recommended for use in all inflowing lines.

Model 167 Back Pressure Check Valves are designed to fit inside Schedule 80 pipe and are for installation in lines that flow into pressure tanks. These valves should be used in inflowing lines when outward flow is never required.

Model 167 Back Pressure Check Valves can be mounted in any orientation. 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.
