1 ORBIT valves will give
maximum performance and
long life when used with an
effective maintenance
program.
2 Lubrication is not used
in ORBIT valves to effect a
seal. It is used only to
reduce friction and wear on
moving parts. The only
exception is the Grease Seal
model which utilizes grease
as a secondary sealant.
3 The recommended
lubrication schedule and
types of grease are shown
at the top of this page.
4 The only tool required
for lubrication is a grease
gun with standard hydraulic
type coupler.
Valves equipped with a
lower tube fitting or a
grease seal fitting require a
safe vent coupler for
lubrication.
This is available from ORBIT
or Alemite, part #G-310428.
5 WARNING! Pressure
containing areas of the
valve can be dangerous if
not handled properly.
If valve is in service do not
remove any parts unless
specifically instructed to
do so by an ORBIT
Representative or ORBIT
repair manuals.
6 All ORBIT valves are
equipped with an upper
lube fitting as shown.
This lubricates the upper
portion of the stem and
the bearings.
No line pressure will be
encountered.
Between two and ten
strokes on the grease gun
provides adequate lube
penetration.

ORBIT RECOMMENDED LUBRICATION SCHEDULE
The frequency of valve lubrication should be based on user's past experience with installed equipment. The following schedule of
lubrication should be used as a minimum guideline until operating experience indicates otherwise:
1. A minimum of once a year.
2. Every time the valve is serviced for stem leak.
3. We recommend quarterly lubrication if valve is operated infrequently (once a day or less).
4. Every 1000 cycles if valve is operated more than 10 times a day.
5. Every 500 cycles if the valve is used in corrosive or other severe services and operated more than 10 times a day.
SPECIAL SERVICE MAINTENANCE
Consult your ORBIT Representative before performing any maintenance on valves in special services such as oxygen, ethylene oxide,
hydrofluoric acid and any other potentially dangerous services.
RECOMMENDED LUBRICANTS
For standard valves we recommend a high quality lithium base grease. For temperatures below -20°F (-29°C) we recommend a low
temperature grease.
The typical fluid used in the gas over oil system is automotive automatic transmission fluid such as Mobil ATF 220 or equivalent.
