Hi,

 

I'm trying to size a control valve for gas service and i'm struggling to plot the valve characteristic curve for a linear and equal percentage valve.

 

Has anyone build a spreadsheet that plots the calculated CVs of the valve on the valve charecteristic curve? For example, in order to check if the selected valve cv operates within acceptable range 20%-80%?

 

thanks in advance

Hello,

Try tables of valve manufacturers.

When you've built your spreadsheet, it might help others if you posted the results of your effort.
