OPERATION OF DURA-CYL 160 / 180 / 200 / 230 / 265 HP

F
illing Procedures
The high pressure liquid cylinder is regulated by the DOT/
Transportation Canada for transporting liquid oxygen,
nitrogen, argon, carbon dioxide, or nitrous oxide. The filling
of these high pressure liquid cylinders must be done by
product weight. This will allow enough gas space above
the liquid to keep the cylinder from becoming liquid full if
its pressure rises to the relief valve setting. The filling weight
table (pgs 47 & 48) indicates the correct product weight
for the various relief valve settings. The standard relief
valve setting is 350 psig (24.1 bar). The filling procedure
will show the proper way to use the filling weight table.
The high pressure liquid cylinder is equipped with a liq-
uid and vent valve that are used during the filling
procedure. The liquid valve is equipped with a dip tube
that extends into the inner vessel of the cylinder and
reaches to the bottom. The vent valve has a dip tube
attached to it that also extends into the inner vessel
of the cylinder. This vent tube is designed to spray the
liquid into the top of the vessel so that pump filling
through the vent valve will keep head pressure down
in the cylinder.
