Style 98 AKII TFE Valve Packing


  • pH 0-14
  • Surface Speeds: to 700 fpm (3.5 M/sec)
  • Pressure:
    Valves to 5,000 psi (344 BAR)
  • Temperatures: to 500°F (260°C)

Services

Style 98 AKII is manufactured from TFE filament yarns with PTFE lubricants incorporated into the fibers. The ANTI-KEYSTONE® Technology allows for easy conformance to valve stem or shaft.

White, non-staining, dimensionally stable Style 98 AKII is inert to all materials except molten alkali metals or free halides.

Applications

Valves handling steam, solvents, and even the harshest chemical solutions. Also effectively seals slow speed pumps, rods, and agitators.


Style 102 AKII Blackjack™ Packing


  • pH 0-14
  • Surface Speeds: to 4200 fpm (21.4M/sec)
  • Pressure:
    2,000 psi (137 BAR)
  • Temperature: to 500°F (260°C)


Services

Style 102 AKII is densely braided from 100% GFO® material, a filament yarn made from finely ground particles of graphite encapsulated in an expanded PTFE matrix. The yarn together with our ANTI-KEYSTONE® II Technology produces the highest combination temperature and surface speed of any TFE fiber based packing.

Style 102 AKII can be used in water, steam, pulping liquors, aromatic and aliphatic solvents and acids. Also effective against petroleum and synthetic oils as well as air and dry industrial gasses. This style should not be used in molten alkali metals and strong oxidizers.

Applications

The low coefficient of expansion, speed capability and good thermal conductivity of Style 102 AKII provides a highly versatile packing suitable for use in a wide range of pumps and valves handling processes in the petrochemical, power generation, metallurgical and pulp and paper industries.


Style 120-P AKII Advanced Food Service Packing


  • pH 2-13
  • Surface Speeds: to 1200 fpm (6.1 M/sec)
  • Pressure:
    1,500 psi (103 BAR)
  • Temperature: to 450°F (232°C)


Services

Style 120-P AKII is manufactured from 100% mix of PTFE fiber and dispersion incorporating a lubricant in just the right amount to resist glazing.

Services include food process fluids of all kinds, potable water, and any process where sanitation is a criterion.

The yarn used in Style 120-P AKII complies with requirements in Title 21 CFR 177.1550. The lubricant complies with title 21 178.3570 for USDA incidental food contact.

Applications

All food handling equipment with rotating shafts, reciprocating rods, rams, presses, and rotating and rising steam valves.


Style 200 AKII PTFE Chemical Packing


  • pH 0-14
  • Surface Speeds: to 2000 fpm (10.1M/sec)
  • Pressure:
    2,500 psi (137 BAR) reciprocating
  • Temperature: to 500°F (260°C)


Services

Style 200 AKII is densely constructed from PTFE filament yarns containing heat conductive fluroplastic filaments. The yarns are uniformly impregnated with PTFE suspensoid and additionally treated with an inert lubricant. A lightly colored lubricated TFE yarn is braided in diagonally opposed corners in our Hydropacking™ design.

Initially designed for bleach valves and towers, Style 200 AKII may also be used against air, oils, solvents, gasses and other fluids where contamination may be a problem. This packing should not be used in molten alkali metals or free halides.

Applications

The chemical inertness of Style 200 AKII provides high speed, non-contaminating sealing where harsh fluids must be contained including rotating pumps, agitators, mixers, and bleach washers. Especially suited for sealing valves in chemical, agricultural and petroleum processing industries.
