The Corroflex® CF300-SS Stainless steel non-return valve is used in high pressure pipelines, and prevents an undesirable flow in the opposite direction to the main flow direction. Mounted in the high-pressure area of manifolds of industrial gas supply systems, the CF300-SS protects the compressed gas cylinders against transfer in the event of incorrect operation. The CF300-SS can be used in supply systems for inert, flammable, oxidizing and corrosive gases up to 6.0 level purity.

Special Features

The unique seat seal design and the use of selected gas-wetted parts allow the use with oxygen up to 300 bar working pressure. The Oxygen ignition test for non-metallic seat sealed check valves which is required during development phase can be omitted with the CF300-SS due to targeted material selection.
