Operating range

Pressure [pmax]: Vacuum … 55 bar
pH: 0 - 14

Temperature: t = -240… +270 °C

Pressure: Vacuum up to 55 bar (according to the operational and/or assembly conditions)

Temperature: Resistance of the ePTFE sealing material short term +310 °C. After first temperature exertion the bolts should be Re-tightened.

Resistant

  • All media pH 0-14, e.g:
    acids, alkaline, solvents, paint, oil, grease, steam
  • Excluded:
    molten and/or solved alkaline metals and elementary or gaseous fluoride at high temperature or under high pressure
  • Ageing resistant

Material

100 % pure ePTFE in a stretched filament knotted fibre structure. This ensures that there is a high pressure resistance (restricted cold flow) and a good adaptation to the flange surface.
