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
