ANSI/ASME vs. API Valve Ratings
ANSI/ASME vs. API Valve Ratings
(OP)
I have a project that is asking me about the equivalence between the two but since I always specify valves based upon the ASME standards for pressure and temperature, flange bolting and the like (even if the valve itself is also governed by an API stanard), so I don't have much experience with the API rated valves.
I recall seeing a chart, possibly within a standard but I can not recall exactly where. Can anyone help?

RE: ANSI/ASME vs. API Valve Ratings
This question comes up a lot, though usually on the valve forum. Did a quick search, here's 2 threads that may provide insights:
thread408-233901: API 6D vs ASME B16.34
thread408-224641: Applicable Valve Tseting Standards vs. ASME B31.3-345.2.2
