Valves are essential components in a wide range of industrial processes, regulating the flow of fluids and gases under often extreme conditions. The proper functioning of this equipment is critical to ensure the safety, efficiency and durability of industrial plants.

In this context, lubrication plays a key role. Krytoxvalve lubricants. (Chemours), are advanced solutions based on perfluoropolyether (PFPE), designed to operate in critical environments, reduce maintenance and ensure flawless operation over time.

Lubrificanti per valvole Krytox: resistenza e affidabilità

The characteristics of Krytox valve lubricants

Krytox offers a range of PFPE oils e PFPE greases formulated to withstand extreme operating conditions. These lubricants are distinguished by:

  • Chemical safety and stability: are inert and non-reactive with most aggressive chemicals.
  • Corrosion resistance: protect metal surfaces from oxidizing and corrosive agents.
  • Compatibility with reactive gases: they work effectively even in contact with chlorine, oxygen, nitrogen oxides and hydrofluoric acid.
  • Insolubility in common solvents, water and fuels: provide long-lasting protection in wet environments and in the presence of aggressive liquids.
  • Non-flammability and non-volatility: enhance safety in industrial applications.
  • Excellent compatibility with gaskets, O-rings and elastomers.: prevent degradation and leakage in valves.
  • Wide operating temperature range: maintains viscosity and lubricating ability even in extreme cold or intense heat.
  • Indefinite shelf life: offer consistent performance over time without degradation.

These features make Krytox valve lubricants ideal for a variety of industrial applications, reducing the number of re-lubrications needed and improving equipment life.

Industrial applications: Krytox for extreme environments

Krytox lubricants are used in a variety of industries, where they provide superior performance even under the harshest operating conditions.

Main sectors

  • Chemical industry: provide protection in the presence of aggressive compounds and reactive gases.
  • Clean energy: are used in hydrogen, geothermal and solar power plants.
  • Aerospace: offer safe lubrication for valves subjected to extreme temperatures.
  • Industrial manufacturing: they improve the reliability and durability of valves in production machinery.
  • Medical sector: ensure reliable operation of precision devices.
  • Power generation: reduce the need for maintenance in valves in power plants and steam plants.

Case studies: the performance of Krytox valve lubricants

I Krytox valve greases and the Krytox PFPE oils have proven their effectiveness in various industrial applications:

  • Mexico: Krytox LPG 105 oil is used to lubricate the moving parts of valves that need to prevent leakage of titanium tetrachloride (TiCl₄), a highly corrosive chemical.
  • South Korea: A valve manufacturer has dramatically reduced damage claims by applying theKrytox LPG 103 oil on the solenoid valve coil, decreasing friction and overheating.
  • Iceland: In the geothermal power plants, the Krytox LPG 206 grease met the high lubrication requirements of steam valve bushings exposed to extreme temperatures and acid gases.
  • Domestic gas industry: The Krytox LPG 205 grease has been used for years for the lubrication of brass poppet valves in domestic gas appliances.

These examples confirm the reliability of Krytox lubricants even in the harshest industrial environments.
