Application Summary AI generated
This standard specifies the design, materials, pressure-temperature ratings, testing, and marking requirements for steel gate, globe, and check valves with nominal diameters of DN100 and smaller. It is applied in the petroleum and natural gas industries for controlling fluid flow in pipelines, processing equipment, and distribution systems where compact, small-bore valves are required. The standard ensures valve reliability and safety under high-pressure and high-temperature conditions typical of upstream and midstream oil and gas operations.
