Stainless steel compressor bleed valves
Improve the reliability and availability of your 7F or 9F gas turbines' critical cooling and sealing air system with GE's stainless steel compressor bleed valves.
Compressor bleed valves are essential components in the startup of a gas turbine. They are also some of the common components to cause trips. It’s a problem that has plagued F-class plant operators (and GE) for many years. After more than a few attempts to solve the main problem causing trips—corrosion in the valve body—we are pleased to offer an alternative to carbon steel valves : Our latest and greatest stainless steel compressor bleed valve.
Upgrading to our latest stainless steel compressor bleed valve will improve your gas turbine’s reliability and could help reduce your annual operating costs. Its 4-way solenoid makes it unnecessary to take in ambient air, which prevents moisture and environmental contamination from entering the valve and helps elimiate clogging. If there is an issue with one of the inlets, the unit will continue to run on the other three inlets, avoiding a gas turbine trip. Each valve’s solenoid and limit switches are pre-wired before arrival at your site, which reduces installation time. The valve assembly incorporates all operational parts required, which means that it will not trigger a fault that can trip the unit.

Key features of the new and improved stainless steel compressor bleed valve
Replacing your hydraulically actuated gas valves and inlet guide vane actuator with electrically actuated gas valves can help ensure long-term system safety and improve the reliability of your gas turbine and accessories.
GE’s valve tracking logic for trip mitigation is an application software enhancement developed to improve TMR robustness and mitigate the risk of unit trip.
Replacing your gas turbine’s exhaust thermocouple (TC) will result in more accurate exhaust gas temperature sensor readings, which will in turn help increase the life of your TC and all associated parts.
GE's latest generation ESM (Exhaust Spread Monitor) improves running reliability, resulting in longer response times to tackle thermocouple faults, along with increased uptime and fewer trips due to more robust handling of failures.
GE’s non-optical flame detector keeps a close watch on combustor operations for the balance of your plant. Get rid of outdated sensors and avoid risky flame failures.
