Xomox CorporationA (perfluoroalkoxy) and FEP (fluorinated ethylene-propylene) primary valve lining materials are used because of their chemical inertness. While FEP is less expensive, PFA can handle higher temperatures. PTFE has some inherent limitations that may make it less appropriate as a lining material. These linings overcome the valve failure problems associated with PTFE linings.
