Packing developed and tested for valves that handle corrosive media at high temperatures

Abstract

Working with valve manufacturers and end-users of molten salts, UK-based James Walker has developed a high-performance packing-ring set suitable for critical valves that operate at ultra-high temperatures and handle chemically aggressive and corrosive media. As this brief article explains, the packing has been successfully field proven for valve stem sealing in applications that involve molten salts, the use of which is increasing significantly – driven by developments within the clean energy sector and industrial processes.
