BYPASS VALVE (BPV)
IDENTIFICATION
FIN: 10HH, 30HH
LOCATION
ZONE: 191, 192
COMPONENT DESCRIPTION
The ByPass Valve (BPV) is electrically controlled and
actuated by a stepper motor. Limit switches signal
fully open or fully closed positions to the pack
controller secondary computer.
Pack controller primary and secondary computers
receive a step counting signal used for the ByPass
Valve position determination.
A manual override and visual position indicator device
is installed on the bottom of the shaft.

RAM AIR INLET (RAI) ACTUATOR
IDENTIFICATION
FIN: 8HH, 28HH
LOCATION
ZONE: 191, 192
COMPONENT DESCRIPTION
The ram air inlet actuator has:
- an AC motor, electrically supplied by the pack
controller (two different motor suppliers),
- two limit switches (one for the closed
position, the other for the 70% open position).
These send signals to the secondary computer,
- two potentiometers (one for control through
the primary computer, the other for
indication through the secondary computer).

ANTI-ICE VALVE
IDENTIFICATION
FIN: 17HH, 37HH
LOCATION
ZONE: 191, 192
COMPONENT DESCRIPTION
The Anti-Ice Valve is electrically controlled and
pneumatically operated.
Anti-ice mode: valve energized.
The valve opens if ice is detected across the high or
low pressure side of the condenser.
Pneumatic temperature control mode: valve
de-energized.
The valve is controlled by a pneumatic sensor to get
a fixed temperature (15ºC or 59ºF).
