Reassembly of the SuperFlow® 350 Demand Regulator
SuperFlow® 350 Regulator
ance hole on the inlet tube. Push forward on the
tool to stop the inlet valve stem from turning. Ad-
just the nut until the free flow stops and there is
1/16
inch (1.5 mm) to
1/8
inch (3.0 mm) of free play
at the end of the lever.
Insert the inlet valve holding tool into
the balance hole on the inlet tube.
6) Remove the inlet valve holder tool.
7) Put the diaphragm and cover in place, de-
pressing the cover tightly to simulate a properly
tightened clamp.
Push down on the regulator cover to
simulate a tightened clamp.
8) Depress the purge button in the center of the
cover.
NOTE: (Reference, instructions following) Before
bending the lever, double check the adjustments.
The lever rarely requires bending. Usually levers
require bending only when improperly serviced,
or if damaged during disassembly.
9) There must be
1/16
inch (1.5 mm) to
1/8
inch (3.0
mm) of free travel before the purge button actu-
ates, resulting in a slight flow of gas. If a slight
flow of gas develops with the purge button de-
pressed less than
1/16
inch (1.5 mm), the lever will
require bending down.
If the purge button travels further than a
1/8
inch
(3.0 mm) before gas flow starts, the lever will re-
quire bending upward.
Test the response of the purge button.
10) To bend the lever up, remove the lever and
carefully place it in a vice. Grip the lever from
the side with a pair of long nosed pliers and bend
the roller end up with your finger. Bend it only a
small amount at a time.
NOTE: Be very careful to not place undue stress
on the lower legs of the lever as this will disfigure
the feet and cause spongy operation.
11) To bend the lever down, place the disk end of
the KMDSI
1/4
inch wrench onto the flat area of
the adjustment tube within the regulator, sliding
the disk as far as possible under the lever. With
your finger, slightly bend the lever down over the
disk to the desired height. Be careful not to bend
the lever too far! Bend it slightly then check it.
