It should be there; it corresponds to the butterfly valve standard you choose.

The standards for the flanges, gaskets, and fasteners that accompany butterfly valves are based on flange standards and have no relation to the butterfly valves themselves; these can be selected in accordance with \"Petroleum and Chemical Pipeline Equipment SH3401~3409\"

HG 20592-2009 is also a good standard
