Richter has achieved a significant advancement: all common product lines such as ball valves, control valves, sight glasses, safety valves, check valves, manual control valves, sampling valves, and magnetic coupling pumps are now available in conductive PFA and FDA-compliant versions. Newly added are the butterfly valves, which also meet these high standards. This development is particularly important for the pharmaceutical and chemical industries as it ensures the highest safety and purity standards. This closes a gap in the product portfolio.
PFA (Perfluoroalkoxy) is a high-performance plastic belonging to the fluoropolymer family. It offers exceptional chemical resistance, high thermal stability, and non-stick properties. The conductive variant of PFA contributes to safety by dissipating static electricity, thus preventing the risk of sparks or explosions caused by electrostatic discharges. Richter’s valves and pumps with plastic linings are specially developed for demanding industrial applications with corrosive media. The conductive PFA lining is particularly important in environments where flammable or explosive materials are processed.
The incorporation of black conductive plastic is done using the transfer moulding process. This process is a special technique for manufacturing components, where molten plastic granulate is transferred into a closed mould under pressure and heat. This method is often used for processing thermoplastic and thermosetting plastics that have specific requirements for strength, dimensional accuracy, and material properties. Compared to the classic injection moulding process, transfer moulding is characterised by particularly high precision and uniform material distribution. Due to this process, a minimum material thickness of 3.5 mm is guaranteed. The result: valves and pumps that meet the highest standards and work reliably in every application.
