Does anyone have the GB/T 122387-89 specification for wafer-type butterfly valve? Thank you in advance!

The standard you want should be GB/T12238-89 "Universal valve flange and wafer connection butterfly valve", not GB/T122387. GB/T12238-89 standard can be downloaded from the following website, which is a free download website. http://www.bzfxw.com/soft/softdown.asp?softid=699

The specification requested upstairs will soon be invalidated. The new GB/T 12238-2008 has been released and will be officially implemented on July 1, 2009. Now a friend in this forum has uploaded it, you can check it out. The download link is: http://bbs.hcbbs.com/viewthread.php?tid=456335
