Compressible flow through valve given Cv/Kv

Compressible flow through valve given Cv/Kv

(OP)
I've seen several equations for sub-critical, compressible flow through a valve given Cv or Kv, inlet and outlet pressure...Can someone shed some light on which to use and when?
the specific application is sat steam flow

Thanks to both of you for the links!  I didn't realize those resources were available online.

RE: Compressible flow through valve given Cv/Kv

All you gotta do is ask Eng-Tips.

If these mfgrs don't know the right equations, we're all in trouble.
