The perfluoroelastomer sealing formulations enable valves to effectively, efficiently, and safely function in oil and gas or chemical processes, it’s declared.
With the sealing specialties, valves can avoid seal life reduction, premature leaks, and higher plant operation and maintenance expenses.
Among sealing challenges addressed are ball valves in flow throttling and full shut-off conditions in an extended range of pressures, temperatures, and chemically aggressive fluids.
The polymer products also safeguard valves in gas cleaning/sweetening. The removal of carbon dioxide and acidic gases like hydrogen sulfide from gas streams — is particularly demanding and potentially damaging. The solvent chemistry together with rapid gas decompression, attacks valves seals and “O’ rings in the valve seat. This company’s application of DuPont Kalrez helps reduce and in many instances, avoid catastrophic failures.
