Valve port diameter labeling issue
Thread Content
What does the diameter indication of 8’’X8’’ on the control valve mean?
The first number is the nominal diameter of the valve, while the second number refers to the flow diameter of the valve seat.
I still don’t understand. Does 8’’X8’’ mean that the nominal diameter is 8 mm? Still 80mm
8 inches, 8“, approximately DN200 in diameter.
I don’t understand; what does DN200 refer to, and where is it located?
This shouldn’t be asked of me; ask the original poster~
2 eights, are you referring to the ones in front or the ones at the back?
One is a passage, and the other is a channel. That’s how I understand it. Can you understand it? ;P
Do you mean that for a DN200 valve, there is a hole with a size of 219.1 inside? :o Please forgive my wild imagination.
