Stem packing rings set


Combination rings is made up of several low-density central pure graphite rings and two high density end rings (2+n form).  A specially designed central shaped ring can achieve a higher pressure coefficient compare to normal shape, improve the distribution condition of the packing compression load, selectively compress and control the radial flow of the packing material to make the packing tightly contact with shaft and seal chamber, in order to achieve more stable, more reliable and long-lasting sealing performance. 

The advantage of combination rings series

  • It is applicable under the condition of high switch frequency

  • It has better compensation ability compare to convertional flat rings

  • It has low friction coefficient which can satisfy the low torque requirements

  • It has wide chemcial adaptability

  • It can hold and resist to flushing with high pressure and high temperature

Technical Parameters

  • Temperature: -200ºC ~ +650ºC (steam)  -200ºC ~ +455ºC (atmosphere)

  • Pressure: 600bar

  • PH value: 0-14(except strong oxidizers)

  • Equipment: Valves in chemical and petrochemcial industries, the control valve of hydrocarbons, oil refinary, steam, power plants and nuclear power plants.
