Packing sets keep valves environmentally clean
A range of high performance control packings, designed to achieve long-term low emission performance from high cycling, fire safe control valves, is now available from Garlock (Great Britain).
Ultra-Flex has an open C cross-section manufactured from an exterior metal sealing material - gold, aluminium, silver or copper, depending on the application - formed over an internal metallic core of Inconel.
On loading the seal during assembly, two opposing offset ridges on the sealing face move into the optimum position as the C section deforms.
The metallic composition of Ultra-Flex provides benefits over elastomer seals including high and low temperature resistance, zero outgassing, reduced contamination and wider chemical resistance.
Ultra-Flex is available in a wide range of sizes and materials either from stock or manufactured to customer specifications.
