Mode of operation of the reversible A pressure regulating
valve:
Supply process:
The reversible B pressure regulating valve splits the supply in
channel (1) and regulates the pressure upstream of the valve
in channel (5) (channel (3) receives the unregulated pressure
from channel (1)). Thereafter the regulated air is switched to
working channel (4). The valve is thus operated in reversible
mode.
Exhaust process:
Venting occurs in the valve from working channel (4) to
channel (1) and in the intermediate plate to the sub−base
exhaust duct (5).
