Supagraf^® FE

• Third party verified emission control performance
• Suitable for both rotary as well as rising-stem valve application
• Ultra-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 7 Fire Safety / ISO 10497:2010
• Suitable for use in valves from pressure Class 150 up to Class 1500 - please consult us for further advice and Class 2500 suitability
• Can mitigate the effects of stem judder and friction by helping to prevent graphite pickup or high spot friction on the valve stem, especially in applications with high rates of thermal cycling and dynamic stem movements

• Supagraf FE is designed for harsh operating conditions where fugitive emissions from valves need to be reduced to well below 50 ppm
• Suitable for all types of valves performing arduous duties handling fluid media such as hydrocarbon liquid fuels, gases including CO2, lubricating oils, and processing chemicals
• Also suitable for valves that handle dry gases and other fluids

Valve stem duties:

• Maximum operating temperature in oxidising conditions: +450°C (+842°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 negligible volatile content.
