Lubricants for Turbines Application

The flow of steam into a steam turbine is controlled by a series of valves, normally driven by a cam shaft and lifting levers. The assembly is collectively known as the “valve rack.” The components in the valve rack operate in an extremely harsh environment. They can be exposed to hot, corrosive, high-velocity steam flow. Conventional lubricants used on these components can quickly oxidize or break down, at which point the valve rack can end up locked in one position compromising speed control over the steam turbine.

Other Steam Turbine Applications:

• Inlet governor valves
• Expansion bearings
• Trip and throttle valves
