What is the difference between the sealing surface of a small valve and a large valve?
Thread Content
The sealing surface of small valves is generally Y (tungsten carbide), and the sealing surface of large valves is H (Cr13 series stainless steel). What is the sealing surface of ball valve F? Why did you choose this?
There is no such choice. The sealing of any valve is related to the medium and the designer.* related to habits
It has something to do with the designers and manufacturers. When choosing one, it mainly depends on the medium of the pipeline.
Don’t waste unnecessary expenses. Sealing surfaces made of different materials have large price differences.
If it's economical and applicable, then save money if you can.
This uncertain ball valve is easier to seal if it is F! ! The material of the sealing surface is generally stainless steel, and some materials may be different from economic considerations! ! ! However, under normal circumstances, just use H. It is not necessary to use Y for small diameters. That is quite wasteful!
Very much the same as the point above. The one we use most is Q41F-16C.
So that’s it, a senior insisted that I insist that the small sealing surface be made of carbide, which made me very depressed.
