Detailed Description
The 2″ Gas Metering Valve is designed to precisely control the flow of gas fuel in aero-derivative gas turbines, including the LM2500. By adjusting fuel delivery based on operating conditions, it maintains the optimal fuel-to-air ratio essential for safe, efficient, and reliable turbine operation.
Fuel metering valves act as the throttle control for gas turbines. Since turbines generate power by burning fuel mixed with compressed air, accurate regulation of this mixture directly impacts power output, efficiency, and emissions such as nitrogen oxides (NOx) and carbon monoxide (CO).
This valve delivers exceptional accuracy within ±1% of the flow point, ensuring consistent fuel delivery and optimal combustion. It is built to perform reliably in demanding environments and meets safety standards including ATEX, PED, and UL, certifying it for use in hazardous and extreme conditions.
The fuel metering valve is a two-inch right-angle style valve commonly used on aero-derivative turbines. It integrates easily into existing systems without requiring hydraulic or electrical changes. With millions of hours of proven field performance, it offers dependable, precise fuel control that enhances turbine efficiency and reduces fuel consumption.
