I did realise that it was for globe valves ....but as yet I cannot find a Kv chart for a straight thru full bore ball valves.

I have a Cv chart for holes of varying dia.

I also thought that flow and the cross sectional area of the hole had a linear type relationship...I.E. A 4 bore would flow 4 times as much as a 2 bore seeing as how the cross sectional area is 4 times as much?

Im not sure that I have my facts right and it really matters not... your flow is more than enough to flip an opponent.
