Installation, Operation and Maintenance Manual
LUBRICATING HANDWHEEL AND OPERATOR ASSEMBLY
Handwheel Operated Valves - Connect a grease gun
containing NLGI grade 2 petroleum base grease to
the 1/8” Alemite type grease fitting on the bearing
housing. Pump in a small amount of grease. DO NOT
OVERFILL.
Bevel Gear Operated Valves - Bevel gears are supplied
by other manufacturers. Consult particular
manufacturer’s instructions. If these are not available,
lubricate the same as Handwheel Operated Valves
above.
Motor Operated Valves - Motor operators are
supplied by other manufacturers. Consult particular
manufacturer’s instructions. Lubricating Seats (6” and
larger valves equipped with seat sealant ports).
Lubricate once a year.
1. Only use grease guns that are equipped with a
pressure gage.
2. Some seat sealants become very stiff or viscous
in cold weather. It may be difficult to pump
some sealants under these conditions.
It is recommended that the grease gun
be kept in a heated area until it is ready to be
used. If this is not possible, contact your local
Cameron Valves & Measurement
representative for low temperature sealant
recommendations.
3. Move the valve to the closed position.
4. Carefully, remove the safety caps on the seat
lubrication fitting using a wrench.
Warning: Back-up the seat grease fitting using a
wrench so only the safety cap will be removed from
the fitting. Carefully remove the safety cap from the
seat grease fitting. NEVER remove the grease fitting
with the valve under pressure!
5. Connect the grease gun to the seat lubrication
fitting(s). (Both sets may be lubricated at the
same time)
6. Pump the sealant into the seat. Once the
pressure rises above the valve rated pressure,
hold for three (3) minutes to promote filling
of the grease grooves.
NOTE: Grease guns can develop pressures far in
excess of the valve working pressure. Use only grease
guns, which are equipped with pressure gages. Do
not exceed the valve maximum allowable
working pressure.
7. Stroke the valve to spread the sealant on the
seat surfaces. (Indicator rod should move
approximated 1” or 25 mm.)
8. Release the pressure in the grease gun and
remove it from the grease fitting. The fitting
ball check should prevent the release
of the valve grease pressure.
9. Install the fitting safety cap and
tighten securely.
10. Repeat for the other seat. Both seats may be
lubricated at the same time, if desired.
