Description

Main areas of application:
• Armatures
• Valves
• Gate valves
• Bullrings for valve and pump packing

Characteristics:
• The high temperature graphite impregnation improves the cross section density and acts as a form stable pressure cushion for the carbon fibres
• Elastic and wear resistant, and has a low coefficient of friction
• Excellent in applications with temperature changes due to carbon and steel having a similar coefficient of expansion
• Recommended as bullring for expanded graphite packing like A44
• When used as pump packing shaft hardness HRC 45 is recommended

Suitable for:
• Power stations, boiler houses, high pressure and high temperature applications
