The Gas Check Valve is a unidirectional valve used in LM2500 gas turbine systems to prevent the reverse flow of combustion gases into critical fuel and oil lines. Its primary function is to maintain the correct flow direction, ensuring that gases only travel toward the combustion chamber and not back into upstream components, where reverse flow could cause damage, safety risks, or system inefficiencies.

This check valve is engineered to operate under the high-pressure and high-temperature conditions typical of industrial gas turbine environments. It serves as a passive safety component, requiring no external power to function, and contributes to the overall reliability and integrity of the turbine system.

Commonly found in aero-derivative gas turbines used in oil and gas applications, the check valve is essential for maintaining proper system performance. Its inclusion in the turbine’s gas path helps ensure safe operation by minimizing the risk of combustion gas contamination in auxiliary systems.

LM2500 Fixture, Hinge – Upper Compressor Case is a specialized tool set designed to safely raise and hinge open the upper compressor case of the LM2500 gas turbine engine. This fixture is essential during major maintenance, inspection, or overhaul activities where access to the engine’s internal compressor components is required.

The fixture allows maintenance teams to lift and securely hold the heavy upper compressor case in a hinged, open position. This provides stable and safe access to the compressor rotor and other internal parts, ensuring technicians can carry out detailed inspections or repairs without risking damage to sensitive components.

Made from strong, durable materials, the fixture set is built to support the heavy upper compressor case while keeping everything properly aligned. Its reliable locking and hinge system holds the case securely in place, helping protect the gas turbine.

Compatible with both OEM and MRO procedures, this fixture supports efficient, repeatable maintenance practices and helps reduce overall engine downtime. Whether used in the field or in a dedicated maintenance facility, the LM2500 Hinge Fixture is a critical tool for safe and effective servicing of the LM2500 engine’s compressor section.

The LM2500 DLE Gas Turbine is an advanced power generation unit designed to deliver high efficiency while significantly reducing emissions. Utilizing cutting-edge Dry Low Emissions (DLE) technology, it precisely controls fuel and air mixing to minimize nitrogen oxide (NOx) emissions.

The LM2500 DLE utilizes a single-rotor gas generator with a 16-stage compressor and a two-stage high-pressure turbine, coupled with cutting-edge DLE combustion technology to reduce nitrogen oxide emissions. It supports dual-fuel operation on a wide variety of fuels, including natural gas, diesel, aviation fuel, LPG, and even hydrogen blends with concentrations ranging from 5% to 95%. The turbine’s open configuration allows for faster maintenance and quicker engine replacement, minimizing downtime.

Its key benefit is utilizing advanced aeroderivative gas turbine technology with dual-fuel Dry Low Emissions (DLE) capability, achieving ultra-low emissions of just 15 ppm NOx on gas fuel, combined with broad fuel flexibility—making it ideal for meeting strict environmental regulations while providing fast, reliable power for dynamic grid demands.

The LM2500+ DLE in a 1x1 combined cycle configuration—one gas turbine, one heat recovery steam generator (HRSG), and one steam turbine—delivers significantly higher efficiency, exceeding 50% in combined cycle mode.

Designed for high thermal efficiency, fast start capability, and reduced emissions, the LM2500 family is widely used across onshore and offshore environments, including industrial plants, pipeline stations, CHP systems, and utility-scale power production.

The DLE combustion system enables the LM2500+ to maintain low NOx and CO emissions without the need for water or steam injection—simplifying operations and reducing water-related maintenance.

Key features include:

• Triple annular combustor design for even temperature distribution and lower emissions across the power range
• Electrically actuated DLE fuel valves replacing traditional electro-hydraulic SAC valves for better control
• 75 pre-mixers in 30 external modules, creating a consistent lean fuel/air mixture
• NOx emissions ≤15–25 ppm and CO emissions ≤25 ppm (on natural gas, full load)

With fast ramp-up—achieving base load from cold start in under five minutes—the LM2500 is an ideal choice for fast-start and cycling applications. This performance makes it well suited to dynamic grid environments and industrial use cases requiring quick responsiveness.

The LM2500XPRESS+G4 DLE UPT is a fast-deployable gas turbine system engineered for demanding oil and gas environments—onshore or offshore. It offers a balanced combination of power, efficiency, and installation speed, making it especially suited for upstream, midstream, and LNG operations where reliable electricity and mechanical drive are critical and timelines are tight.

At the core of this system is the LM2500+G4 gas generator, a proven design that delivers higher output and efficiency than earlier models, thanks to improvements in airflow, thermal capability, and cooling. It strikes a solid middle ground in the 20–40 MW class—powerful enough to support heavy oilfield infrastructure but lighter and more flexible than larger industrial turbines.

The Dry Low Emissions (DLE) combustion system helps meet environmental regulations without relying on water or steam injection—a major advantage for remote or offshore sites where water supply is limited or emissions compliance is strict.

The Upgraded Power Turbine (UPT) adds flexibility in terms of shaft speed and load-following, which makes this unit adaptable for various oil and gas power demands—from continuous baseload operation to backup and peaking support.

Its XPRESS configuration emphasizes rapid deployment. The turbine is delivered in a compact, modular format, pre-assembled into a small number of transportable units with simplified electrical and mechanical interconnections. This minimizes site work, shortens commissioning time to a matter of weeks, and reduces exposure to remote-site construction risks.

The 3” Gas Fuel Isolation Valve is a solenoid-pilot actuated sleeve-style valve designed specifically for aero-derivative gas turbines. It features a three-inch outlet flange and operates on dual voltage ranges of 24 or 95-140 VDC, providing flexibility for various power systems without compromising performance.

Constructed entirely from stainless steel, the valve complies with NACE standards for corrosion resistance, ensuring durability in harsh environments. It is engineered to withstand heat soak temperatures up to 300°F, making it suitable for high-temperature applications commonly found in turbine fuel systems.

Certified to CE-ATEX standards for Zone 2, Group IIA, Category 3, T3 temperature class, the valve is qualified for use in hazardous and explosive atmospheres, enhancing operational safety.

This valve acts as a critical safety device by isolating the fuel supply during emergency shutdowns or fuel system failures, preventing potential damage to the turbine. Typically deployed in pairs, it offers dual-redundancy to maintain safety even if one valve fails.

The valve is widely used in industrial gas turbine fuel systems where rapid and reliable fuel isolation is critical. Its design supports fast shutoff to prevent damage caused by fuel control failures or stuck throttle conditions.
