Valve identification on P&IDs

Hi all,
I'm just doing a small inquiry. We have had discussions at work on the value of putting valve tags on the P&IDs; the valve identification code that is in the piping specifications for hand opertated valves. Currently this isn't done. All that shows up on the P&ID is the valve symbol, so if it is necessary to know more, e.g. trim, handwheel or gear op., etc. you have to go to the piping specifications. Our construction group are pushing for it as it will make their job easier when they do a final walk through of the systems. Engineering are reluctant because of the amount of work and the possibility of error. We do produce isometrics from a 3D model which has a complete BOM, which includes, of course, the valve tags.

What's your experience? Value added or not?
