Re: Valve identification on P&IDs

Thanks for the quick response Michael.
The tags I'm refering to are pre-determined valve codes. These are an assigned code from which you can ascertain the valve properties. Such things as: Valve type (gate, globe, etc.) end connections (flanged, BW, etc.), rating, material, trim, handwheel or gear operator, and so on.

To answer your questions:
a) These numbers/codes are predetermined and just need to be noted against the valve on the P&ID.
b) These are in the client spec.'s.
