When the pack switch is in the HIGH position, solenoid B de-energizes (high
flow mode). Actuator air flows to the APU/high flow servo. The high flow
servo has a strong bias to close. This will let more air pressure go to the
valve actuator. This increases airflow. High flow mode is 105 ppm.
In cruise, if a pack shuts down from an overheat or if a (L or R) pack switch
is OFF, solenoid B de-energizes. This sets the operating pack to high flow
mode.

Solenoid A energizes when the all of these conditions are true:
• Pack switch is in the HIGH position
• APU bleed switch is in the ON position
• APU operates above 95%
• Airplane is on the ground.
When solenoid A energizes, the FCSOV operates in the APU high flow mode.

The APU high flow mode energizes solenoid A. The APU /high flow servo
has one more actuating piston than high flow. This results in a higher
spring-bias to close the servo. This lets more pressure go to the valve
actuator. APU/high flow mode has an airflow rate of 131 ppm.
