What are the standards for socket gate valves?

The standards for socket gate valves mainly include national standards, American standards, and industry specifications, as detailed below:  

- National standards: GB/T 12234 “Design and Manufacturing Standards for Steel Gate Valves Used in Petroleum and Natural Gas Industries”; GB/T 14383 “Connection Dimensions Specifications for Socket-Welded Fittings”; GB/T 13927 “Pressure Test Requirements for Industrial Valves”.  

- American standards: ASME B16.34 “General Standards for Design and Manufacturing of Valves”; ASME B16.11 “Connection Dimensions Specifications for Socket-Welded Fittings”; API 600 “Manufacturing Specifications for Steel Gate Valves”; API 598 “Inspection and Test Standards for Valves”.  

- Other specifications: API 602 “Standards for Small-Diameter Forged Steel Gate Valves”; JB/T 7746 “Structural Dimensions and Design Specifications”.  

Socket gate valves that comply with the above 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 withstand pressures of up to 42 MPa.
