The valve model is SD342F1-150R7; could you please tell me what the meaning of these letters is?

In a process diagram, the valve model indicated is SD342F1-150R7. I would like to ask what the letters “S”, “F1” and “R7” each mean
Check valves, fluoroplastics, Mo2Ti series stainless steels
According to the common naming rules for valves, the letter “S” usually indicates the type or series of the valve. The letter “F1” may indicate the function or characteristic of the valve; for the specific meaning, it is necessary to refer to the technical documentation or specifications for that model. The letter “R7” may indicate information such as the material or specifications of the valve; it is necessary to consult the specific technical documents or specification sheets to determine its meaning. .
Only those who have developed this model understand it; sometimes, in order to achieve a goal, things are written carelessly{:9005:}
This is the material list provided by the design institute:
It clearly looks like nonsense written randomly:lol:lol:lol
Finally, I found it – it indeed refers to a “telescopic butterfly valve”:
I know that, but could you explain what F1-150R7 means?
If you don’t believe it, you can check GB T 32808-2016; it’s purely a matter of personal habit on the part of the design institute
For butterfly valves, look at these three codes: 342: lol
