NSF 61 Certified Flange?

[mdefense]

Working on a project that has to be nsf 61 certified for potable water contact, but cannot find a flange the connects to a butterfly valve. The valve we are proposing to use is a 2" nominal ANSI class 150 inlet/outlet. Any suggestions?

Why don't You use a flange acc. Asme B16.5 class150#.
That's normal I suppose.
