Improved Sealing: The flexible graphite’s ability to “flow” provides significantly better sealing. This can be especially true in valves where the sealing surfaces are rough or where large clearance tolerances exist between the body and bonnet joint.
Thermal/Pressure Stability: The thermal stability of Graphite pressure seal ring will withstand the frequent cycling that occurs in fossil and nuclear stations. Low Cost: Graphite pressure seals are an economical alternative to metallic seals.
