Hi fellow forumers,
Currently I am doing a control valve simulation on HYSYS. I have the valve datasheet that already specified the parameters including flow, valve opening, valve CV etc.
I am trying to mimic the datasheet (which i know that i cant because the valve manufacturer may use their own software on sizing the valve). However, I tried to simulate the valve, and I found that at given flowrate and delta P, when I increased the valve opening, the Cv actually decreased. I thought that increasing the valve opening will lead to increasing Cv.
Hope I can get some insight on this. Thank you
