CV request choke valve
CV request choke valve
(OP)
Hello at everyone,
I must to design a multiple orifice choke valve.
I have the following data at the maximum:
flow: 13500 MMSCFD
Inlet pressure: 1300 psig
Temperature: 200°F
Outlet pressure: 300 psig
Specific Gravity: 0,683
State of fluid: Vapor
How do I calculate the Cv request?
I tried in ISA 75.01 but I don't understand some parameters like xt and other.
I have confused ideas.
Someone help me please.
Thanks to all.

Another question on this topic. I have to calculate the noise with IEC 60534-8-3. My problem is the jet diameter Dj.
If I have a cage with holes calculated as per the rules: I find Fd, valve style, with the formula dh/d0, knowing the number and size of holes? If it's a positive or adjustable choke which is the jet diameter? corresponds to the bean?
There is also a way to know the size of the bean without first passing through tests or CFD analysis?
Thanks
