Plug and socket welded wedge gate valve - A182Gr.F316 CL3000
Thread Content
Does this mean that the entire valve is forged from 316, or does it refer to the seal being made of 316?
Generally, it depends on the specific circumstances. For DN40 and below, the components are usually forged as a whole, while for those above DN40, the housings are cast; however, it is also necessary to consider factors such as pressure to determine whether a forged component should be used or some other approach. These are personal opinions and may not be accurate.

The diameter is DN10. There are two issues at present: 1) it’s not clear whether the valve body is made of 316 material or only the sealing surface is; and 2) what is the corresponding pressure rating for CL3000 in gate valves?

There must be a problem with this; the nominal diameter is too small. There can’t be such high pressure
I just asked – for DN10 valves, the term \"overall forged part CL3000\" refers to socket-welded fittings; the corresponding value for valves is likely CL900, which is perfectly suitable.
For the previous question, check floor 3~~ For the next question: besides CL3000, there are also the 6000 and 9000 grades~~ Note: These are just grades; there is no exact correspondence with pressure levels~~
So, what determines this level of 3000?
Check SH/T3410~~~
;P;P~~I said it clearly on the 8th floor~~~I wonder if it wasn’t read properly~~~“~Note: 3000/6000 etc are just grades~and there is no exact correspondence with pressure~~” It’s merely a term used to denote the grade of a forged product; there’s no need to worry about it. If you want to find out more, read ASME Volume B carefully...
