PFA-Lined diaphragm valve resists aggressive chemicals

Bürkert has introduced a range of PFA-lined stainless steel diaphragm valves for use with aggressive chemicals. The PFA liner is a fluoropolymer that offers users the benefits of similar chemical resistance to that of PTFE against most aggressive chemicals and acids, but with much lower levels of porosity. It is also tolerant of higher temperatures, with the capability for operation up to 260 degrees C.
