For butterfly valve, AWWA covers up to 72". What else cover larger? Thanks! Good weekend, everybody!

David,

The ASME B16.1 standard has flange size range to NPS-96, while the AWWA C207 standard has flange sizes to NPS-144.

Check the design pressure ratings of each standard. There are other international standards which could be applied.
