Supagraf^® Premier

• Third party verified emission control performance
• Suitable for both rotary as well as rising-stem applications
• Low friction performance without graphite pick-up reducing the torque needed for efficient valve action
• Fire safe capability confirmed by third-party certification according to API 607 Edition 4 Fire Safety

Supagraf Premier is designed for harsh operating conditions where fugitive emissions from all types of valves need to be reduced to well below 50 ppm. This packing is well proven and widely used in systems handling fluid media such as hydrocarbon liquid fuels, gases including CO2, lubricating oils, and processing chemicals.

Valve stem sealing duties:

• Maximum operating temperature in oxidising conditions: +450°C (+842°F)
• Minimum operating temperature: -200°C (-328°F)
• Maximum system pressure: 25 MPa/250 bar (3626 psi) - consult us for advice on use at higher pressures
• Certified pressure in BSM valve: 69 MPa/690 bar (10000 psi)
