HT 9650/HT

Features

BuraTAL HT is a completely new design of packing set consisting of the following components:
  • Braided end rings of expanded pure graphite with carbon fiber-reinforced corners
  • High-density expanded pure graphite sealing discs as a diffusion barrier
  • Specially impregnated adapter rings made from high-density, expanded pure graphite
  • Lower-density sealing ring made from expanded pure graphite with a smooth, friction-reducing coating.

Advantages

  • Low spindle torques
  • Minimal leakage rates

Operating range

Valves
Pressure: p = 300 bar
Pressure: p as per TA Luft: 80 bar
Sliding velocity: vg = 2 m/s

Temperature
  • Continuous operation:
    t = -200 °C … +400 °C
  • Steam: tmax = +550 °C

Chemical resistance:
pH = 0 ... 14
Resistant to most chemicals (solvents, hydrocarbons, acids, alkalis), steam, alcohols, oils, water etc.

Standards and approvals

  • TA-Luft
  • Leakage test to API 622
  • Fire safe to API 589

Variants

9650/HTB (with live-loading System)

Notes

Valve sealing kit – for high pressures and temperatures, particularly in TA Luft applications, for standardization without live-loading.

Forms of supply

  • Custom-made packing sets
  • Individual dimensions available upon request

Special variation of a sealing set for valves at high temperatures. Rotatherm- high precision seals deliver optimal sealability, low diffusion and exceptional service life. Complemental to the very low wearing of the sealing faces this high temperature and high pressure sealing set is able to adjust as well gaps of the valve components. A special version (graphite rings with a thin, elastic stainless steel cap to bridge large gaps and reduce oxidation) is available for applications above 550 °C.

BuraTAL T3 9650/T3

The BuraTAL T3 9650/T3 an innovative new packing set made from high quality, impregnated non-wovens. It consists of the following components:
  • Carbon fiber non-woven end rings with a special PTFE/ graphite compound.
  • Aramid non-woven sealing rings in the middle impregnated with PTFE to ensure very high cross-sectional stability. The packing set is especially suitable where high gas sealing performance with low friction is required.

BuraTAL T4 9650/T4

The BuraTAL T4 9650/T4 an innovative new packing set made from high quality, impregnated non-wovens. It consists of the following components:
  • Two carbon fiber non-woven rings impregnated with a special PTFE/graphite compound on the atmospheric side.
  • Three aramid non-woven sealing rings on the product side impregnated with PTFE to ensure very high cross-sectional stability.

The packing set is especially suitable in applications that demand elimination of contamination by the media and where high gas sealing performance with low friction is required.
