Control Valve Sizing Parameters.
Control Valve Sizing Parameters.
(OP)
Our control valve data sheets show (limited) process data as follows:-
Temperature - norm/max
Inlet press - norm/max
Min. flow @ DP
Norm. Flow @ DP
Max. Flow @ DP
My question is, what pressure & temperature numbers should be used to calculate the valve cv ?
For min flow cv, I would use normal press/temp values
For normal flow cv, I would use normal press/temp values
For max flow cv, would I use max press/temp values ??
Thanks.

But we need to know your process. what is the process fluid?
