May I ask the experts: when selecting a control valve, is it based on the principle of taking the higher of 125% of the upstream operating pressure or 110% of the shut-off differential specified in the instrument datasheet?

It depends on where you use it; it varies from case to case

I usually choose from the selection software; I’ve never encountered this issue

Asking the control valve manufacturer is the most direct and effective approach.

I passed by and learned about it; generally, we determine this based on the location where it will be used and the medium involved in its use.
