Richter PFA-lined ball valves KN/F and KK/F have been type-approved by TUEV and are suitable for use on road tankers, tank wagons and transport containers. They comply with the German Clean Air Act (TA Luft).
In addition to compliance to European regulations, the ball valves, BVA and KA-N, have been certified by the AAR (Association of American Railroad) in the USA (AAR Manual Section C, Part III, M-1002).
PFA/PTFE-lined butterfly valves are used on acid tank ships. Further examples are PFA-lined diaphragm valves as filling and drain valves on special bromine containers and PFA-lined magnetic drive pumps on road tankers for faster unloading, eg, H2SO4.
The integral PFA fluoroplastic lining has many advantages in that it is much more resistant to corrosion than the alternative materials. It is an anti-adhesive vacuum resistant lining which is easy for CIP (clean in place) and can be also used for high-purity and for solids-laden fluids with large temperature ranges from up to -60 up to 200°C.
The seal-less, magnetic drive centrifugal pumps are fitted with integral PFA lining and are equipped with a hydraulically optimised closed impeller. The pumps are also hermetically tight with no rotary shaft seal thus requiring minimal maintenance.
