What are the standards for pneumatic butterfly valves in different countries and regions?

The pneumatic butterfly valve standards in different countries and regions are as follows:

1.  American standards: American pneumatic butterfly valve standards mainly include ANSI standards and API standards. ANSI standards include ANSI B16.34 (steel valves), ANSI B16.5 (pipeline accessories), ANSI B16.10 (valve face-to-face dimensions), etc. API standards include API 609 (butterfly valve design and manufacturing), API 598 (valve testing and inspection), etc.

2.  European standards: European pneumatic butterfly valve standards mainly include EN standards. EN standards include EN 593 (butterfly valve design and manufacturing), EN 12266-1 (valve seat sealing performance test), etc.

3.  Japanese standards: Japan's pneumatic butterfly valve standards mainly include JIS standards. JIS standards include JIS B2064 (butterfly valve design and manufacturing), JIS B2003 (valve testing and inspection), etc.

4.   Chinese standards: China's pneumatic butterfly valve standards mainly include GB standards and HG standards. GB standards include GB/T 12238 (butterfly valve design and manufacturing), GB/T 13927 (valve testing and inspection), etc. HG standards are industry standards for China's chemical industry, such as HG/T 20592 (butterfly valve design and manufacturing), HG/T 3091 (valve testing and inspection), etc.

    In addition to the standards of the above countries and regions, there are also standards of many other countries and regions, such as British Standards (BS Standards), German Standards (DIN Standards), etc. According to specific application needs and international trade requirements, choose the appropriate standards for selection and application.
