Graphite ring
Expanded graphite ring
for high temperature valve applications
Graphite ring is characterised by a high level of chemical resistance and thermal stability as well as excellent sealing effect and constant elasticity.Regardless of temperature cycle this material is not subject to cold flow, shrinkage or ageing.Graphite ring fulfils the purity requirements for seals in nuclear power station valves (content of soluble chlorides < 20ppm). Also available with corrosion inhibitor.
