Supagraf® Control

A long‑term, high integrity sealing solution for control valves.

  • Control valves
  • Oil & Gas
  • Valves

Supagraf Control is an innovative compression packing that provides long-term, high integrity sealing for control valves. Its very low friction enhances the control accuracy of valves. This is a 'best available technique' product for reducing industry's VOC fugitive emissions in line with the European Union's IPPC Directive.

It is manufactured in exfoliated graphite, reinforced in a novel way with a non-metallic structure to provide additional strength and resistance to pressure and extrusion. An advanced lubricant system is incorporated to prevent the pick-up of graphite on valve stems.

  • High integrity gland sealing for control valve stems: to well below 50 ppm fugitive emission level
  • Long-term adjustment-free operation: over 100,000 stem strokes with emission levels below 50 ppmV
  • Very low coefficient of friction for smooth and accurate valve action
  • Reduced friction requirement to save on power consumption and enable smaller actuators to be used

  • Designed for emission control - to better than 50 ppmV leak tightness - on control valves in systems handling fluid media such as hydrocarbon liquid fuels and gases, lubricating oils and hazardous process chemicals
  • It is a long-term replacement for the PTFE V-type packings that can be readily damaged by ingress of dirt and other foreign particles to the gland area

Valve stem duties:

  • Maximum operating temperature: Up to +350°C (+662°F)
  • Minimum operating temperature: -200°C (-328°F)
  • Maximum system pressure (standard): 25 MPa/250 bar (3626 psi) - contact us for advice on use at higher pressures

Compatible with media in the range of pH 1-14 excluding strong oxidising agents. The product has low volatile content.

  • All popular square sections from 3 mm (1/8") upwards in boxes containing 8 m (26' 3") in coil form or on spools as detailed in the product datasheet
  • Also supplied as split preformed rings and sets
  • Non-standard square or rectangular sections made to order
  • Please refer to the product datasheet for spool ordering information

  • TA Luft/VDI 2440
  • ISO 15848-1 Class BH, CC3
