Features

Isartherm A 6011/A is a diagonally braided graphite fiber packing with a heat-resistant and innovative special impregnating agent. The packing is ideal for use in the high pressure and hot steam range, particularly for valves in power station technology, refineries and the petrochemical industry. It is also well established in practice as a header ring or where the gap geometry is unknown or the sealing surfaces are not optimal.

Advantages

  • High cross-sectional stability
  • High structural strength
  • Wear-resistant
  • Gentle on spindle surfaces

Operating range

Valves
Pressure: p = 300 bar
Sliding velocity: vg = 2 m/s
Fans
Pressure: p = 8 bar
Sliding velocity: vg = 5 m/s
Mixers, agitators, kneaders
Pressure: p = 50 bar
Sliding velocity: vg = 5 m/s

Temperature
  • Continuous operation:
    t = -40 °C … +450 °C
  • Steam: tmax = +550 °C

Chemical resistance:
pH = 2 ... 12
Particularly suitable for hot water and hot steam applications. Not suitable for concentrated acids and alkalis.

Notes

Isartherm cannot be used as a cover seal or self-sealing gasket. For such applications we recommend the Statotherm pure graphite or V-Flex cover seals which have proven their worth over a long period.
