Ball valve valve implements national standards

1. Introduction to national standards
Ball valve is a commonly used valve type, which is used in a wide range of industries, including petroleum, chemical, metallurgy, electric power and other industries. In order to ensure the quality and safety of ball valves, the state has formulated relevant standards and specifications.
Second, the national standard for the implementation of ball valves
1. GB/T 12237-2013
This standard stipulates the material, structure, manufacturing, testing, acceptance and other requirements of metal shut-off and regulating ball valves, and is suitable for metal ball valves with a working pressure of 1.6-32MPa and a working temperature of -29°C~425°C.
2. JB/T 8691-2010
This standard stipulates the material, structure, manufacturing, testing, acceptance and other requirements of spherical taper sealed steel valves, and is suitable for spherical taper sealed steel valves with working pressure of 1.6-10MPa and working temperature in the range of -29°C~200°C.
3. HG/T 3704-2016
This standard stipulates the requirements for the material, structure, manufacturing, testing, acceptance and other requirements of ball valves, and is suitable for ball valves with a working pressure of 1.6-42MPa and a working temperature of -196°C~600°C.
