Can anyone tell me how valves are rated for water, oil, and gas. Is there a specification for testing valves for a specific WOG rating. and how are these test performed?

All steel valves and fittings shall have a steam rating of at least one hundred fifty (150) psi, ANSI standard, with a minimum WOG rating of 250 psi. Valves of material other than steel shall have a pressure rating of at least two hundred (200) psi steam, or four hundred (400) psi WOG.

Absolute micron rating. All (not just 98%) particles larger than the stated micron size that will be removed from the fluid being filtered. ... Nominal filter rating. Indicates the approximate particle size for which a majority will not pass. It generally means 85% of particles of this size will be retained.

I guess it worthwhile to mention that “WOG” is short hand for “Water Oil & Gas.” The “S” on some valves is for the “steam” rating which is always a smaller number than the WOG rating.
