Standard System Connections
a. The DynaPak 2010 requires a 3/4” FNPT
pipeline connection (1/2” for J version).
b. The DynaPak 2010 sampler should be
mounted vertically in a horizontal run of the
pipeline.
c. The end of the sampler probe should
penetrate the center 1/3rd of the pipeline.
d. The end of the sample probe should be cut
parallel to the pipeline.
e. Before applying pipeline pressure to the
DynaPak 2010, ensure that the isolation
valve and purge valve are good.
f. After pipeline pressure has been applied to
the sampler, check the probe body/pipeline
connection using a liquid leak detector.
CAUTION:
Overtightening of valves can re-
sult in damage to the valve components which
might result in the valve stem being screwed
out of the probe body. This, of course, results
in product at pipeline pressure being vented
continually through this port until this section of
the pipeline is shut in. DynaPak valves are of
soft seat design and should only be closed or
opened with fingers. Wrenches should never be
used. If a valve will not seal off with finger tight
operation the valve should have maintenance
performed to allow proper operation of the
valve.

NOTE:
At temperatures below 32˚ F (0˚C), condi
-
tioning of the actuation gas supply may be required.
Where the actuation gas supply has a high water
content and/or a low hydrocarbon dew point, addi-
tional actuation gas filtration or heating of the actua
-
tion gas supply may be necessary. Bottled nitrogen
gas can also be used during cold operating condi-
tions to avoid condensation in the actuation gas sup-
ply line. In addition, operation at extreme tempera-
tures will affect seal and diaphragm performance.
To prolong the service of seals and diaphragm,
adequate heat should be provided to maintain an
operating environment above 32˚ F (0˚C).
