The NPRSOV functions as a redundant regulator to the HPRSOV and
will remain in the full open position under normal operation conditions.
In the event of a failed open HPRSOV, the NPRSOV will regulate the
conditioned bleed air pressure to approximately 70 psig. From the
NPRSOV, the conditioned bleed air is ported to the environmental and
wing anti-ice systems.
The HPRSOV and NPRSOV can be closed by selecting the associated L
ENGINE BLEED or R ENGINE BLEED switch to OFF.
