Braided from expanded graphite tape,with reinforcement and a special PTFE film coating
Characteristics
• Avoids ‘slip-stick’ effect
• Excellent in MOV and AOV control valves
• Easy to cut, assemble and disassemble
• We recommend die formed rings
• Non-hardening, good reset capability, coefficient of thermal expansion similar to steel
• High cross section density and sealability to minimize emissions
• Wear and extrusion stability through structure reinforcement
• Low coefficient of friction minimises adjustment force on valve steam
• Rings should be compressed 20-25% of their height during installation
