Herose cryogenic check valves

A check valve is used to secure against undesired return flows in pipelines, as it allows the flow of gases or liquids only in one direction. In the cryogenic area specially designed check valves are required, which are up to the requirements of temperatures well below freezing point. Cryogenic check valves are available in sizes from DN10 to DN200 and secure pressures up to 50 bar, at operating temperatures of -196°C to +120°C. The check valves are manufactured in stainless steel and bronze.
