Supagraf^® Control

• 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.
