Which valve design document is the most authoritative?

******Which source of information on valve design is the most authoritative? Even among the materials compiled by Lu Peiwen, there are differences in many calculation formulas in books such as \"Introduction to and Mastery of Valve Design\", \"Design Techniques and Catalogs for Gate Valves\", and \"Practical Valve Design Manual\"; differences also exist between different versions of the Valve Design Manual.
According to product standards and their standard systems
For the calculation of the sealing specific pressure in a conical shape as well, the formulas in Zhu Peiyuan’s design manual 2 to 4 are different, not to mention those used by other people. I think there are errors in these design manuals. And many things are only briefly mentioned
It’s really difficult for a design manual to cover everything perfectly and in just the right way: lol
