I found a valve size calculator,https://www.gregraven.org/hotwater/calculators/valve-sizing.php, but it seems to produce results that seem off (too small) for ACVW's. Can anyone tell me why?

Cheers,

Paul

It seems to predict roughly the minimum valve sizes to run X rpms, at a 72% flow ratio, which is a bit low IMO. I like the classic 75%

No adjustment for valve stems size or sear widths.
