API valve trim numbers
API valve trim numbers
(OP)
From what I've been able to discern, it appears that the API series of valve trim numbers are defined in API 600 and 602. Are there any other sources that define the trim number? The reason I ask is that we were recently supplied with a 3/4" CL 2500 check valve, trim 16. API 600 is only for gate valves and API 602 only covers up to CL 1500 so this valve is outside the scope of both of these standards. I realize that the trim number just indicates what material is used for the various trim components, but the questions becomes a little stickier when you consider that the charts in each of the standards for alternative trim numbers are different.
Can I extend the trim definitions from API 600 and 602 to the valve in question or is there a different standard that covers this valve?

My focus is on valve stockists in the us and us who supply duplex and super duplex valves, and inconel and hastelloy valves, plus titanium, alloy 20 and 904L valves.

My focus is on high-alloy valves in incoloy, and titanium valves, and inconel and hastelloy valves, plus 254 SMO, alloy 20 and 904L valves.

API 594 "Check Valves: Wafer, wafer- Lug, and Double Flanged Type" does cover class 2500 but only goes down to 2" in size
Chances are you valve was constructed per ASME B16.34.
API is close to publishing the API 623 Globe valve standard. Inside of API 623 there will be trim table.
