Choose a medium and a duty and this recommends a valve type and body material, cross-checked against what we actually stock. General selection guidance, not a substitute for a specification review on an unusual duty.
What is the valve for?
Three questions, in the order a specifier actually answers them: what is flowing, what the valve has to do, and roughly how big the line is.
Common questions
Is this tool specific to one standard or brand?
No — it covers general valve-selection practice found in any piping/valve handbook, not a brand-specific or standard-specific rule. It recommends a valve type and body material, then shows what we actually stock that matches.
Will this tool get the dimensions wrong the way the flange or pipe-weight tools might?
There is no dimension to get wrong here — the risk with this tool is different: a duty this simple ruleset does not fit well, such as high-cycle control, sour/H2S service, cryogenic temperature, or a pressure or temperature outside the ordinary range for the material shown.
Can I order directly from this tool's recommendation?
Treat it as a starting point, not a specification — the result panel ends in an enquiry link rather than a final answer. An unusual or hazardous duty needs a specification review before ordering.
