Supagraf® Premipak

A superior combination packing set for valves based on two class‑leading graphite products.

TYPICAL APPLICATIONS
  • Control valves
  • Stop valves

Supagraf Premipak is a superior combination packing set for valves. It is based on two class-leading graphite products.

End rings: Supagraf Premier braided high purity 98% graphite filament packing for high strength and extrusion resistance with excellent sealability, plus third-party certification to TA Luft, API 622 or ISO 15848-1 emission control requirements. These rings conform to Shell material specification MESC SPE 85/204.

Intermediate rings: Special moulded rings of high purity graphite foil, that offer low friction and excellent heat transfer characteristics, plus high efficiency sealing. These rings conform to Shell material specification MESC SPE 85/203.

  • Reduced valve stem shudder and hesitation
  • Low break-out friction
  • Long working life with minimal maintenance

  • Stop valves and control valves performing arduous duties with media such as hydrocarbon liquid fuels and gases
  • Most applications require VOC fugitive emission control to 100 ppm or better, with a maximum working temperature of up to +450°C (+842°F)

Valve stem duties

  • Maximum operating temperature: +450°C (+842°F)
  • Minimum operating temperature: -200°C (-328°F)
  • Maximum system pressure: 25 MPa/250 bar (3626 psi)

Compatible with media in the range of pH 1-14 excluding strong oxidising agents.

  • As precision moulded rings in endless form or with single split, to meet customers’ requirements
  • Sections: 3 mm to 40 mm (1/8" to 19/16"). Diameters: 5 mm to 500 mm (3/16" to 19 3/4") ID

  • Shell MESC SPE 85/203
  • Shell MESC SPE 85/204
