Combining Style 98 carbon fiber packing and GRAPH-LOCK® cup cone molded rings to form a nearly chemically inert package.

When tightening the packing gland, the 9000-EVSP® simplifies radial expansion of the kit, resulting in a positive stem OD seal and stuffing box ID seal.

Features / Benefits
  • Patented "cup cone" design allows selective component compression and controlled radial flow to effectively seal ID and OD
  • The end ring acts as a scraper ring to limit the transfer of graphite particles while preventing extrusion and providing additional elasticity
  • Patented "cup cone" design provides tightness in a valve as shallow as a three-ring cross section
  • For deep stuffing boxes requiring more than 7 ring kits, machined / open carbon fiber bushings can reduce box depth
  • Class 250 (Style # 4525) for general applications
  • Class 580 (Style # 4540) for nuclear applications
  • End ring selection: Style 98 (general conditions) or Styles G-700 or 1398 (nuclear conditions)
specification
  • Minimum temperature: -328 ° F / -200 ° C
  • Maximum temperature: 850 ° F / 455 ° C
  • Maximum valve pressure: 10 000 psi / 689.5 bar
application
  • Oil and gas industry processing
  • Any valve application where scaling, chemical attack or health hazards need to be eliminated
