Statotherm V Cover seal V901 rings are high precision seals, which give a very good sealing result with excellent service life in combination with very little wear. The profile rings are made from permanently elastic, expanded graphite (purity >99%) without binders. Statotherm V Cover seals V901 are used as self-sealing gaskets in high-pressure valves e.g. for power plants at high temperatures and up to approx. 1,000 mm diameter.
  • Easy installation and removal
  • No damaging of the seal surfaces
  • Long service life
  • No hardening
  • Optimized sealing solution
  • Minimal wear of surfaces
