ASME B16.34 - Off spec valve classes
ASME B16.34 - Off spec valve classes
(OP)
I've been working on specifying a wye pattern globe valve and I've noticed that it seems quite common in valve catalogs to specify these valves as class 1690 and class 2680. Are these classes related in any way to the ASME 16.34 valve classes? I cannot find a spec anywhere that uses these numbers yet the manufacturers tend to refer to ASME B16.34. Can anyone explain this to me? Thanks.

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.
