Material requirements for PTFE-lined valves
Thread Content
Are there valves lined with PTFE, both gate and ball valves? Can the stem of a regular lining valve be lined? What materials are generally used for fillers? Is there anyone who can provide drawings of lining valves, including the materials used for various internal components of the valves? @The valve is clearly there
There is information here; you can go and download it – it should be useful to you. Fluoromeric valves and pipes produced by Fluomi Company have been a reliable supplier for large chemical enterprises such as Sinopec and Sinochem for a long time. http://bbs.hcbbs.com/thread-1365438-1-1.html (Source: Haichuan Network)
I took a look; the samples don’t show any materials with fillers. Do you have any cross-sections that show how the inside of the valve is lined?
Why bother to know it so thoroughly? Are you an organization or something else?

I see, the filler is usually made of PTFE
Thank you. Is there also a lining on the valve stem? I saw it clearly stated in the sample that it’s made of metal material
The valve stem does not come into contact with the medium, so it’s fine
A small part of the valve is in contact with the medium
