I am an instrumentation engineer. I am working on Ammonia plant revamp project. i have a question regarding the data to be put in butterfly control valve datasheet. is it necessary to mention Flow direction/flow action for a butterfly control valve? I understand the above to are required for a globe valve as the action on plug, but is it applicable for a butterfly control valve?
Trim type in datasheet for a butterfly valve: will be double or triple offset?
