Application Summary AI generated
GB/T 21385-2008 specifies the design, materials, manufacturing, testing, and inspection requirements for metal-seated ball valves, which are used in fluid systems requiring high sealing performance under extreme temperatures, pressures, or corrosive media. It applies primarily to industrial pipelines in sectors such as petrochemical, power generation, and metallurgy, where soft-seated valves would fail due to harsh operating conditions. The standard ensures reliability and safety in applications like oil and gas transport, steam systems, and chemical processing.
