Available evidence
A public pressure-seal globe page may list body, stem and disc features beside size and class ranges. Use that information to write questions about construction. Require the manufacturer to confirm the pressure-temperature basis for the selected materials and to say whether the quote is a manual globe or a complete process control-valve assembly with positioner. Catalog Cv values without fluid and differential pressure are not first-article evidence.
What does the source not establish?
Public ranges do not establish that a particular valve has been tested for your fluid, that a brand-appointed reseller relationship exists, or that installation, training and commissioning are included. They also do not fix end-connection dimensions or actuator orientation against your piping layout.
