More reliable: cost/weight

Use weight multiply by steel price and use a factor (e.g. 6) and this will do as a "installed price" for a rough estimate (process piping)

Try a cataloug or talk to the vendor.

Many valve manufactors has great web sites with all sorts of info.

Try google if you dont know any manuf. by hart or talk to a colleague wich manufactor you usually use.

If you're trying to build a spreadsheet or program that estimates your valve and pipe weights/costs based on nominal size and pressure I don't think your results are going to be all that accurate. Valve costs/weights will vary considerably depending on type, trims quality level, and so on.You might try building and maintaining a separate database or spreadsheet with weights and costs direct from your vendors, then drawing your values from this into your estimating spreadsheet.
