Krytox Steam Control Valve Lubricant
Krytox grease meets the need for a continuous lubrication cycle.
Steam control valve lubricant application at a geothermal power plant
The power plant, located in Iceland, utilizes hot steam from the earth, containing 1–4% gas, mostly carbon dioxide and hydrogen disulfide, in temperatures ranging from 120–200 ºC (248–392 °F). A standard hydrocarbon-based grease was unsatisfactory for lubricating bushings for valves that control the flow of high temperature steam containing corrosive gases.
The Challenge
The geothermal power plant needed a steam control valve lubricant that:
- Is able to withstand presence of acidic gases in high temperature steam
- Has low friction for accurate control of the valve position
- Can work in a self-greasing system
The Solution
Krytox GPL 206 grease met the challenge for lubrication of the steam valve bushing. It provided the low static friction and no stick-slip that is required for accurate position control. Krytox GPL 206, like all Krytox oils and greases, can withstand very high temperatures, is nonflammable, inert, and has a low environmental footprint. The power plant now enjoys reduced maintenance, thanks to high performance Krytox lubricants—standing up to tough conditions.
Other Valve Applications
- Any valve-handling that could react with, degrade, or dissolve standard lubricants. Examples include:
- Steam
- Aggressive/reactive gases
- Chemicals
Fluorinated lubricants from Chemours can also be used successfully in other types of applications. These synthetic oils and greases are ideal for many conditions, such as:
- Continuous high temperatures up to 288ºC (550 °F)
- Use around hazardous chemicals
- Need for low friction coefficient
- Where flammability is a concern, including reactive gases and oxygen service
GPL 200-207 Greases
Krytox™ GPL 206 grease has an Oil Viscosity of 243 cSt at 40°C and the estimated useful temperature range is -36°C to 260°C.
