I have calculated the CV and C values using software. What should I do next to determine the diameter and model of the control valve? ?

If the calculation software belongs to a certain manufacturer, it will be selected automatically. After performing software calculations, one can refer to the manufacturer’s selection samples and apply the appropriate CV value series to determine the relevant specifications.

I was wondering why the CV value calculated by my software is so high? ? What is the unit? ?

Is it necessary to refer to the rated CV value of the control valve when selecting samples based on the CV value? If the two CV values are similar, can this control valve be used? ? ?

At least the first range that is higher than the calculated CV value must be used, and the opening range also needs to be checked in order to determine whether it can be selected. Learning a craft?

The CV value is dimensionless; I’m not sure about your software, so it’s hard to say.

Could you also help calculate it to see if the resulting CV value is roughly the same as his? ?

When selecting a valve, the manufacturer’s CV value should be higher than the CV value you calculate by one order of magnitude~~

What is the unit of the CV value calculated by this software of mine? The value seems really high ?
