The Packing O-Ring is a sealing made from durable fluorocarbon rubber, designed for use in high-temperature and chemically harsh environments. Commonly used in gas turbines such as the LM2500 series, it provides a tight seal between components to prevent the leakage of fluids or gases.

This O-ring has an inside diameter of 27/64 inches, a thickness of 5/64 inches, and a hardness of 75 Shore A. It is built to handle operating temperatures from -20°F to 400°F, making it suitable for sealing joints in systems exposed to fuels, oils, and high pressures.

Its compact size and resistance to compression set and fluid exposure make it ideal for use in shafts, housings, and valve assemblies where reliable sealing is critical to turbine performance and safety.

The LM2500 is a multi-shaft gas turbine featuring a free-spinning power turbine, making it well-suited for dynamic and high-demand environments such as those found in oil and gas operations. In this design, the high-pressure turbine and compressor are mechanically independent from the low-pressure power turbine. This separation allows the power turbine, which drives the electric generator or mechanical load, to respond rapidly to changes in load demand. Its ability to accelerate quickly makes it ideal for applications where maintaining grid stability or mechanical output is critical. In scenarios where frequency fluctuations occur, the free power turbine can quickly compensate, helping to stabilize the grid and ensure smoother operation of all connected systems.

In its standard configuration, the LM2500 is equipped with a six-stage, low-speed power turbine. This turbine operates at a nominal speed of 3600 rpm and is designed to deliver reliable shaft power in steady-state conditions, making it particularly effective for electric power generation or mechanical drive in pipeline and process operations.

For applications requiring greater flexibility or higher continuous output speeds, the LM2500+G4 variant offers enhanced capabilities. It is available with either the standard six-stage, low-speed power turbine or an alternative two-stage high-speed power turbine. The high-speed variant is engineered for mechanical drive and other demanding industrial uses, with a design speed of 6100 rpm and an operating range from 3050 to 6400 rpm. This configuration supports continuous high-speed shaft output where needed and is particularly beneficial for compressors and other rotating equipment in oil and gas facilities.

Both the six-stage and two-stage power turbines can be operated over a cubic load curve, providing the adaptability required for variable load profiles commonly encountered in oil and gas operations. This flexibility, combined with the LM2500’s rapid response characteristics and modular design, makes it a dependable choice for critical infrastructure in upstream, midstream, and downstream sectors.

The 4″ butterfly bleed air valve plays a crucial role in controlling the flow of compressed air, called bleed air, from the compressor section of a gas turbine. This airflow regulation helps maintain safe and efficient turbine operation by managing pressure and protecting internal components.

This valve is built with a strong bearing shaft and specially designed bearings that handle frequent cycles, ensuring a longer service life and less maintenance. It includes a fail-safe feature that automatically opens the valve if a problem occurs, protecting the turbine from damage. With a quick response time—fully opening or closing in less than 320 milliseconds—it reacts fast to changing engine conditions. The valve’s electric components are also better insulated from heat, improving reliability even in harsh environments.

What makes the 4″ valve stand out is its ideal size and performance. It offers greater airflow than smaller valves, yet remains compact and easier to fit than larger ones, making it perfect for medium-duty applications where space and precise control are important.

Importantly, this valve is designed as a direct, plug-and-play replacement for existing models. It requires no changes to the hydraulic or electrical systems, allowing for quick upgrades without downtime. This seamless fit and reliable operation help ensure your gas turbine runs smoothly and efficiently, reducing costs and increasing uptime.

The 3” Globe-Style Gas Metering Valve is designed to deliver accurate and consistent fuel control in industrial gas turbines, including both Dry Low Emissions (DLE) and Single Annular Combustor (SAC) engine types. This valve ensures that the correct amount of gas fuel is metered into the engine based on real-time operating conditions—essential for achieving stable combustion, optimal turbine performance, and reduced emissions.

With an accuracy of ±3% of flow point and a full-stroke response time of 175 milliseconds, it supports precise adjustments to the fuel-to-air ratio, even under fluctuating load conditions. This level of performance is critical for maintaining turbine efficiency, lowering NOx and CO emissions, and supporting regulatory compliance.

The T5.4 thermocouple is a temperature-sensing probe used in LM2500 gas turbines to measure exhaust gas temperature (EGT). The label T5.4 refers to its specific position in the turbine\'s exhaust thermocouple array—zone T5 (turbine exhaust), sensor 4. These sensors are part of a system that monitors thermal conditions at multiple points in the exhaust stream.

This thermocouple operates in high-temperature environments, withstanding continuous exposure up to approximately 1100°C. It is built to maintain accuracy and reliability under the thermal stress and vibration typical in gas turbine applications.
