Threaded Ball Valve Class 2000 vs 3000 CWP

Threaded Ball Valve Class 2000 vs 3000 CWP

Threaded Ball Valve Class 2000 vs 3000 CWP

(OP)
Hello everybody

I am new in North America and try to get my head around all the standards, classes for pipes, fittings and valves. I was reading a lot about abusing the # symbol for classes and so on. However, there are still a couple things I don't understand.

1. Where can I find the the pressure ratings for threaded ball valves outlined as "Class 2000"?

2. I came across a customer pipe spec., which outlines for ball valves "Class 2000" and "3000 CWP" at the same time. Now I am just wondering if this is the same standard or how is the cold working pressure (CWP) interchangeable with the class 2000?

Thanks a lot
Rico

RE: Threaded Ball Valve Class 2000 vs 3000 CWP

I am from the gas industry, and in general a THREADED ball valve has the following pressure ratings, assuming it meets ANSI B16.11: 2000 psig (or 2000#), 3000 psig, or 6000 psig.

2000 psig is referred to as "standard", 3000 psig is extra strong or XS, 6000 psig is double extra strong XXS. I believe that if your customer is wanting a threaded ball valve "class 2000" he is wanting a standard (2000 psig working pressure) ANSI B16.11 valve. These are common up to about 2".

Now he may be referring to a class 2000 flanged/weld-in ball valve which is very different. This would be a specific (non threaded) ball valve with API 6A 2000 psig flanges. These could be a variety of sizes. You should verify what exactly he is wanting.
