FLOW CONTROL PRODUCT SEALS
21 September 2012
Ball valves, utilising a drilled-through ball rotating in a retaining socket, are widely used for process line control operations within industry.
Ball valves offer both flow throttling and full shut-off conditions – applications can involve an extensive range of pressures, temperatures and even the use of chemically aggressive fluids. The importance of specifying the right sealing products for use within these valves is paramount.
Specialist sealing company, Dichtomatik, provides the Kalrez range of perfluoroelastomer ‘O’ rings from the Dupont Performance Polymers range, which have been formulated to provide superior sealing qualities for even the most difficult applications.
In a recent problem application involving gas sweetening, DuPont Kalrez Spectrum 7090 seals have been fitted. These perfluoroelastomer products offer an excellent combination of chemical compatibility, with both RGD and high temperature resistance for ‘O’ ring applications.
