Control Valve Pressure Drop
Control Valve Pressure Drop
(OP)
To All:
I want to know how to calculate the pressure drop across control valve for compressible fluid (gas or vapor). I dont want to use fisher CV gas sizing equation as i have Masoneilan Control Valve. Can anyone tell me step by step procedure. I kanow inlet CV pressure, CV of Control Valve, and physical properties of gas flowing through control valve, Gas flow through control valve.
I would appriciate your help.

In this web page you can find some information about the steps to follow in designing a stpe valve. It can be very helpful.

Tell me if it was.

Thanks for your references, but i went to that site before and i found that it is only for Liquid case they dont have anything for Compressible fluid. It doesnt include expansion factor Y. But i agree that for basic control valve sizing, that is very good information.
To StoneCold,
I can calculate the pressure drop form Masoneilan Control Valve software but i want to know how they calculate it. I mean i want to know the equations used to calculate it.
Thanks
Hardy
