Can a self-acting control valve be used in the pressure testing of a newly installed piping system?

Do you all have any regulations or statements on this matter? . .
Just use the adjustment directly; control it according to the required parameters.
It’s best not to bring valve instruments in at all
It is best to install it after the pipeline pressure test and purging are completed.
The control valve needs to be removed to prevent dirt from getting in and affecting its performance
It’s best not to do it. First, there’s a risk of dirt getting in, which can significantly affect the valve’s sealing performance and adjustment accuracy. Second, if the quality of the valve is poor, it’s likely to get damaged; it’s recommended to remove it and test its pressure resistance separately
