Gate valve packing graphite ring problem
Thread Content
What size graphite packing rings should be used for the packing of DN100--DN500 gate valves? Are the sizes of graphite rings standard?
It is not a standard part and must be produced by surveying and mapping.
Filling size is standard! It depends on how big the packing ring is to be made!
It is not a standard part and requires actual surveying and mapping.
Now that the surveying and mapping is done, are you ordering it according to size?
You can also cut and press the packing on site by yourself, and select the specific size suitable for the filling bin.
