Hello everyboy,

I discover this great website while googling for how to calculate Kv number of a valve.
I am not interested in any software, I would like to find some literature or book about it. My aim is to make my own Excel sheet.

I have not been able to find any reliable source of information for all valves: liquid line, suction line, superheated gas, etc.

Thank you very much in advanced for your help. ^^
