We offer ball valves with all wetted parts lined with PFA.
Because of its superior corrosion resistance, it has been used for highly corrosive fluids for which metal valves cannot be used, such as process lines in plants where acid and alkali flow alternately.
It has also been used in locations where non-stick properties are required.

For your reference, the body of the diaphragm valve has a shape suitable for lining construction, so in addition to PFA lining in accordance with the condition we can, also, offer a wide range of rubber materials (hard, soft, natural rubber, chloroprene rubber, butyl rubber) and ETFE, glasses, porcelain. So, a suitable selection for your application can be available from an extensive lineup.
So in case "corrosion resistant valves" are necessary, please consider not only ball valves but also diaphragm valves.
