I would be really grateful if anyone can suggest reference regarding multiphase control valve sizing.
Thank You

Emerson provides free software at their site. But best to have the valve manufacturer size the valve for you.

as general comment, do not expect accurate results adding CV for liquid and gas phases calculated separately,
vapor and liquid phases can be mixed,
there are papers discussing this matter (see the work of Schmidt etc.),
in Europe there are valve's manufacturers as Samson (samsoncontrols) which created specific software (not sure if it's available to public).
also Prode (prode.com) has code for these applications (control valve sizing with vapor+liquid flow)
with two models, HEM and HNE,
note that flow coefficient is (by definition) the normalized flow rate through the valve,
and you can assembly a general correlation.
You may find papers or contact the mentioned companies for additional information.

Dear all
Good day!
Please find below the required downloadable documents from official sites of different valve manufacturers
The literature available is good for learning but if you really want to size the valve then it is better to use vendor supplied software
To comment on what you are doing please do share your evaluations
Best regards and God Bless You

Attyub194 has linked (from Samson site) one of the works by Schmidt and Diener which I mentioned in my previous post,
this is based on HNE (simplified, see omega method) model,
a different approach is that based on rigorous HEM model, for this I know a code by Prode but probably others can offer similar features (ask manufaturers)
