This video explains the operation and control of the FT8 sixth stage bleed valves, showing how eight-stage LP compressor air, solenoid valves, and spring loading work together to open and close the valves to prevent compressor surge. It also covers the unique features of the right-hand valve, including the quick-exhaust device for rapid depressurization during deceleration, along with practical inspection and functional test methods. The closing and opening speeds, normal operating conditions, and shutdown uses—such as washing and turbine heating—are also identified.
