The 2.5″ Butterfly Bleed Air Valve is a critical component in the LM2500 gas turbine, responsible for regulating the flow of bleed air—compressed air extracted from the turbine’s compressor stage. This valve helps control internal pressures and temperatures, which is essential to maintain safe and efficient turbine operation.

The valve has an effective flow area of 2.5 square inches, allowing it to manage airflow precisely in smaller turbine setups or space-restricted environments. Its butterfly-shaped disc is permanently attached to the shaft, which ensures consistent movement and reliable control of air flow with minimal play or slippage.

One important feature is its fast response time—less than 320 milliseconds to complete a full open or close stroke. This quick action enables the turbine control system to rapidly adjust pressure levels, preventing overheating and reducing mechanical stress on turbine components.

The valve’s bearing shaft is robustly designed to handle frequent small movements, known as dither cycles, without premature wear. The bearings themselves are specifically engineered to support these high-cycle conditions, improving the valve’s durability and lifespan.

By efficiently managing bleed air, this valve helps protect the turbine from excessive pressure build-up and thermal stress, which can otherwise lead to damage or reduced efficiency. Its design also allows installation without requiring changes to the turbine’s hydraulic or electrical systems, making it suitable for retrofits or upgrades on existing LM2500 turbines.

In summary, the 2.5″ Butterfly Bleed Air Valve plays a vital role in controlling compressor bleed air in LM2500 turbines, balancing safety, performance, and durability within compact or smaller turbine applications.
