Valves for natural gas transportation in pipelines - Performance requirements and tests (Austrian Standard)
This European Standard applies to all valves (plug valves, ball valves, gate valves and check valves) used in onshore transmission pipelines for transport of natural gas in accordance with EN 1594. It comprises all valves which are components of the pipeline. The standard specifies valves for pipelines with a maximum operating pressure (MOP) over 16 bar. Excluded from the scope are control valves, safety valves and all valves smaller or equal to DN 50. This standard lays down specifications on requirements and appropriate verification tests carried out in production and for certification purposes to give proof that the valves comply with the requirements.
