Lionpak® 5402 - Graphite packing with low friction for control valve accuracy

Lionpak 5402 is a combination packing for control valves. It comprises a core of expanded graphite yarn reinforced with multiple Inconel® wires, and is further jacketed with fine Inconel wire mesh. Outer section of the packing is braided with high strength, low friction, carbon yarn that will not score the valve stem. It also incorporates an inorganic passive corrosion inhibitor, and James Walker’s proprietary graphite-based dispersion to enhance sealability.
 

• Specifically designed for control valves where very low stem friction is needed for accuracy of fluid flow control
• Adapts to worn surfaces and pitting for smooth running for control valve accuracy
• Recommended for high pressure duties
• Dissipates heat without chemical hardening
• Corrosion inhibitor safeguards metallic interfaces from galvanic corrosion
• Graphite-based dispersion acts as a blocking agent
• Easy to cut neatly for accurate sizing and butt joints
• Easy to remove from gland at plant shutdown

Typical applications
Highly recommended for control valves. Can also be used on other valve types and soot blowers. Suitable for duties with non-oxidising fluids, hydrocarbons, gasoline, fuel oil, lubricating oil, thermic fluid, ammonia, amines, dyes, chemicals and acids.

Chemical properties
Chemically inert within the range pH 0-14, excluding strong oxidising agents.
