API, DIN, BS, GB structure comparison:

API 600 and BS1414, BS 1873, BS 1868, and BS 5351 have the most detailed regulations on the structure of valves.

DIN gate valve standard EN1984 does not specify the structure.

The new version of GB/T12234 is based on the equivalent adoption of the API600 standard
