SECTION FOUR A: RDC REPAIR / MAINTENANCE / OVERHAUL
Cleaning / Inspection of the
ICS Regulator
1.
Wipe off as much old lubricant as possible
from components, using a lint free cloth.
2.
Using the detergent solution, and a soft
bristle brush, clean all metal parts and
components to remove all traces of dirt,
debris and old lubricant. Use a brass brush to
remove corrosion.
3.
After drying carefully inspect for signs of dirt,
contamination, corrosion and damage. Look
for pitting and crevice corrosion, and worm
tracking, which could cause sealing problems.
Replace any damaged components.
4.
Check all threaded components for signs of
galling. Replace any components, which show
any signs of galling or damaged threads.
Carefully check the poppet assembly (2), for
signs of damage, especially around the cone
area. The cone area should be free of
scratches and pitting. If the cone is scratched,
it can often be re-surfaced, using 1200 grit
cloth, or polishing compound. If the scratches
do not remove easily, it is best to replace the
poppet.
After
cleaning
and
inspecting
components,
containerize
to
prevent
contamination and set aside.

EGS Valve Cleaning and
Overhaul
Disassembly
1.
Using the flat blade screwdriver, loosen and
remove the valve handle retainer nut (8),
then remove the spring (7), and knob (6).
2. Loosen and remove the packing nut (3),
then remove the washer (5), and unscrew the
stem (4), counter-clockwise and remove.
3. Remove all the old Teflon® tape from the pipe
threads on the body.
4. Clean all parts, using detergent solution.
5. Corrosion should be removed, using 50/50
white vinegar and water, then blow or air dry.
6. Carefully inspect all components for signs of
contamination,
corrosion
and
damage.
Inspect the pipe threads of the valve body, for
signs of damaged threads. Replace the valve,
if the valve body is damaged in any way.
7. Carefully inspect the valve stem for signs of
corrosion and damage, replace the stem if
any damage is present.
8. Inspect the packing nut for signs of cracking,
damaged threads, and corrosion. Replace the
nut if any damage is found. The packing in
the nut need only be replaced, if the Teflon®
packing shows deep grooves, or appears worn
NOTICE
The EGS valve is manufactured by Kirby Morgan. The
valve will go for many years without the need to
replace components, as long as it is kept clean, and
lubricated. Normally a good cleaning inspection, and
re-lubrication is all that is needed to maintain
serviceability.
