Please ask the experts to provide standards related to valves

Thread Content

Hello, experts! During work, it was found that the current specifications and types of valves do not quite match the previous standards, and the symbols used to indicate these specific specifications are such that it is difficult to determine their exact meaning when compared with relevant standards. Who can provide some relevant information? Thank you in advance! !

JB/T 308-2004 Valves – Method for Naming Models (replaces Standard 75) http://bbs.hcbbs.com/thread-4370-1-22.html Different manufacturers also have their own numbering systems

http://www.bzfxw.com is a standard sharing website, and http://www.anystandards.com is a standard sharing platform; most standards for valves can be found on these two sites.
