Rotatherm 0911/B

Rotatherm 0911/B For a larger view, please mouseover the image.
Rotatherm 0911/B rings are made from permanently elastic, expanded graphite (purity > 98 %) without binders or fillers. Therefore this profile rings are almost maintenancefree, for severe temperature changes and /or extreme temperatures. The packing is a standard solution for all media in boiler systems (process and small boiler installations).
  • Good deformability
  • Permanent resilience
  • Long-term flexibility
  • No hardening
  • Long service-life
  • Excellent sealing action with very low wear of sliding surfaces
Pressure: p = 500 bar

Spindle and stuffing box room have to be clean and in excellent condition. The valve must be in the open position for installation of the rings so that the spindle can be rotated inward to the closed position after installation.
Die-pressed rings, acc. to drawing, measurements or other agreements.
In different densities and profiles.
