All large bore ORBIT
valves are also equipped
with a lower lube fitting
in the pressure area of the
valve. This is a safe vent
lube fitting.
8
Remove the cap slowly
to be sure the ball check in
the fitting has sealed off
the line pressure.
Do not remove any parts
other than this cap.
9
Thread the safe vent
coupler to the lube fitting.
Before attaching the grease
gun be sure the output
capacity is higher than the
line pressure.
10
Two complete strokes
on the grease gun provide
sufficient lubrication.
Cycle the valve if possible to
evenly distribute the grease.
Excess grease will discharge
into the system piping.
11
ORBIT Grease Seal
valves are equipped with a
safe vent lube fitting in the
seat area of the valve.
12
Lubrication is identical
to steps 8 - 10 except
lubricate until the leak
stops.
13
All ORBIT valves
(except O.S.&Y. design)
equipped with diaphragm
actuators are lubricated
through the upper lube
point on the valve bonnet.
No line pressure will be
encountered.
Two strokes of the grease
gun provide adequate
lubrication. Excess grease
will make the position
indicator difficult to see.
14
O.S.&Y. ORBIT valves
equipped with diaphragm
actuators are lubricated at
the lube point on the
adapter sleeve* above the
line pressure.
Two strokes of the grease
gun provide adequate
lubrication. Excess grease
will make the position
indicator difficult to see.
* New style ORBIT diaphragm
actuators have grease fitting
installed in actuator case.
