International standards applicable to process ball valves
Thread Content
In actual chemical engineering projects, problems with valve standards are often encountered. For example, for ball valves, if the long-distance pipeline is very simple, API6D is sufficient. But for switching valves in chemical equipment, what standards should be applied? These valve requirements should be completely different than line valves. I see that API608 is sometimes used, but this standard is only applicable to the American standard below 300 pounds. What standard should be applied to high-pressure ball valves?
High-pressure ball valves should adopt this standard. ANSI B16.34, MSS-SP-61, and ASME standards are used in many imported ball valves in China, including Mogas, Vti, flowserve and other brands.
