7.8.8 Inspection of SuperFlow
Regulator Parts
After the regulator has been disassembled, clean and
inspect all parts. Any parts showing signs of wear,
damage or deterioration should be replaced. If this is
an annual overhaul KMDSI recommends replace-
ment of the inlet valve seat, adjustment nut, O-ring
on inlet valve, O-ring on adjustment shaft, washer
on the adjustment shaft. A rebuild kit is available for
replacement parts (Part #525-309).
If any parts show any signs of damage, deterioration
or any damaged threads, the part should be replaced.
The adjustment nut must never be reused. Reuse of
the adjustment nut will not allow the regulator to
maintain proper adjustment.
1) Exhaust valve: Ensure the silicone exhaust valve
shows no signs of damage, brittleness or any defor-
mities. The exhaust valve should lay flat against the
seat. If conducting an Annual Overhaul, the exhaust
should be replaced. Ensure the seat spokes that hold
the exhaust valve are smooth, even and not bent.
Slight bends in the spokes may be removed by press-
ing with a thumb. The exhaust valve seating area
should be free of dirt and corrosion to ensure the valve
can lay flat and seal properly. NEVER lubricate the
valve. Lubricating the valve can allow dirt to stick to
the seat causing poor performance and wet breathing.
2 ) Inlet valve: Check the condition of the rubber seat
for wear and/or deep grooves. If the red silicone seat
surface is stained to a dark color, this is an indication
that the air supply being used was dirty,
Check the condition of the inlet nipple. The inlet
nipple sealing edge must be in good condition, free
of nicks, chipped chrome or any damage. If the inlet
nipple sealing edge has nicks or missing chrome,
the inlet nipple as well as the soft seat will require
replacement. During annual overhaul the inlet valve
soft seat should be replaced.
3) Inlet Valve Soft Seat Replacement: To replace the
soft seat use a small screwdriver or O-ring pick to pry
the soft seat from the chrome plated brass valve body.
Using a sewing needle clean all old silicone sealant
from the vent hole in the bottom of the cup area, and
from the cupped area itself.
