What is the equivalent pressure class?

[SmithsJohn2]

NC 150 = JIS 10K, 16K or 20K or 40K??
NC 300 = JIS ????

I only know NC 150, 300, 600, but don't know the corrsponding JIS class.
Thanks.

NC150=20K

thanks,

should be ANSI 150, ANSI 300, not NC 150, NC 300.

Actually ANSI 150 is not really correct. Specify ASME B16.5 then use ASME Class 150, ASME Class 300, etc.

Someday I will get used to ASME valve ratings instead of ANSI. When I was a little kid just starting out in this business I used to run across ASA ratings for valves, which were superseded by ANSI.
