cost of valves

[psozot]

how to determine cost of various sizes of valves including ball,gate,globe valves with class 150. is there any thumb rule like "cost/inch"

 

[MortenA]

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.

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.

we are talking +/- 40% here (thats my suggestion weight/installed cost)
