What are the standards for socket gate valves?

The standards for socket weld gate valves mainly include national standards, American standards, and industry specifications, as detailed below: The national standard GB/T 12234 specifies the design and manufacturing requirements for steel gate valves used in the petroleum and natural gas industries; GB/T 14383 outlines the connection dimensions for socket weld pipe fittings; GB/T 13927 establishes the pressure testing requirements for industrial valves. The American standards ASME B16.34 provide general requirements for the design and manufacturing of valves, ASME B16.11 specifies the connection dimensions for socket weld pipe fittings, API 600 outlines the manufacturing specifications for steel gate valves, and API 598 defines the inspection and testing standards for valves. Other relevant specifications include API 602, which covers small-diameter forged steel gate valves, and JB/T 7746, which provides information on structural dimensions and design specifications. Socket weld gate valves that meet the aforementioned standards are widely used in high-pressure, high-flow applications such as the petrochemical industry, power systems, and natural gas transportation. They can operate in temperature ranges from -29°C to 550°C and can withstand pressures of up to 42 MPa.
