GR8622 API 622 APPROVED

GR8622 is an API 622 3rd Edition certified low emission packing for first-use seals and maintenance of industrial valves. It keeps its elastic properties and sealing performance over time without the need for re-tightening.

• Temperature
  GR8622 can be used equally in cryogenics at -200°C and at very high temperatures up to 650°C with non-oxidising fluids and up to 450°C with weakly oxidising fluids and hot air.
• Pressure range
  In order to work under any pressure condition, GR8622 was designed with specially reinforced expanded mineral graphite yarns, impregnated with the latest generation lubricant and passive corrosion inhibitor.
• Ph Range
  GR8622 can be used with the whole range 0 to 14, with the exception of strong oxidants.

Suitable for pressure classes up to API 10000.

Applications

GR8622 was designed for VOC and VHAP fluids and mostnon-oxidising chemicals, but it can also be used for H.P./H.T. steam valves. With GR8622, you can manage the maintenance of all the valves in the plant with a single packing, thereby reducing warehouse costs and potential packing choice errors.
