the enclosure from right to left, these ports are for the
expansion tank drain, the pipeline connection, and the
expansion tank pressure connection.
Two valves located this manifold control the flow of
the odorant blanket gas through the manifold. The
valve located on the left, with the blue knob is the

normal operation, both valves are closed. The bypass
valve is opened to empty the NJEX of odorant,
to Section 12: System Maintenance, page 74 Figure
while the purge valve is opened as part of pre-
paring the system for operation

An integral wafer check valve is built into the odorant
discharge manifold. The wafer is located on top of the
plug that is inserted in the bottom of the manifold. This
check valve is located in the fluid path between the
pump discharge connection and the pipeline connec-
tion port.
The gage located on top of this manifold displays the
Expansion Tank pressure.
NJEX Gas Filter
A 25 micron coalescent filter is provided with each
NJEX. This filter,
figure 177,
is installed on the back
outside of the enclosure and should be connected to
the regulated
(5.2 Bar)
actuation gas supply provided
by the system operator. By conditioning the incoming
actuation gas, a clean pneumatic supply will be pro-
vided to the solenoid valves. This will ensure a longer
operational life for the pneumatic control system. If
the actuation gas supply has a high water content and
/ or a low hydrocarbon dew point, additional filtra-
tion and heating of the actuation gas supply may be
necessary. Bottled nitrogen can also be used as an
alternate gas supply source if gas conditioning is a
problem.
