Valve packing is generally used in high pressure applications.
The packing contains no extractable materials such as oil and remains non-porous even under extreme temperatures. The construction has a fine surface texture to make it pliable against the valve stem and is by design very extrusion resistant.
Carbon-filament yarn with high-temperature graphite impregnation.
The high-temperature graphite impregnation raises the cross-section density and acts as a stable pressure cushion for the carbon fibres
Braided from expanded graphite tape, with inconel wire matrix reinforcement and a special PTFE film coating
High cross section density and sealability to minimize emissions
Braid made of flexible, expanded natural graphite foil with a 10-myh wire mesh reinforcement per braiding strand.
Highest-quality pure graphite gives a coefficient of expansion similar to steel.
Braided from specially formulated expanded graphite, reinforced with a proprietary inconel wire matrix and impregnated with a Passive, Inorganic Corrosion Inhibitor
- Universal plant wide use in all block and manual valves
- Extrusion stability through ultrafine Inconel metal mesh reinforcement on each braided strand
- Passive Corrosion Inhibitor to protects valve stems
Braid made of flexible, expanded natural graphite foil.
Superb emergency running capability, no wear on the shaft, excellent thermal conductivity
Braid made of flexible, expanded natural graphite foil with an integrated Inconel reinforcement per fibre strand.
Highest-quality pure graphite gives a coefficient of expansion similar to steel
