The non-return valves are used in pipelines for the storage, transport and production of liquid gases and provide protection against the unintentional backflow of gases or liquids. The check valves are used at operating temperatures from -196°C up to +120°C and are available in nominal sizes from DN10 – DN50 and in the pressure range up to 63bar. The valves can be designed with stainless steel (series 2142) or gunmetal body (series 2182).
