I am going to size a control valve for following condition:
flow condition:steam
P1=41bara
P2=33bara
temperature=410c
specific gravity=11.7
Z=0.98
what would be the amount of Cv?

Also, you might need to invest in a Crane Technical Paper 410 "Flow of Fluids." It will let you actually calculate your Cv yourself. Used ones are available if you don't want to spring for the money for a new one (which is rather expensive if you're not in the U.S.)

I could give you a Cv right away but I'm out of town on business right now and don't have access to my spreadsheets.
