ORBIT Installation, Operation
and Maintenance
P R O C E S S V A L V E S

To achieve maximum performance and to prolong equipment life, it is important to have correct
installation and proper maintenance.
ORBIT Valves and Actuators are designed to require a minimum amount of maintenance.
Lubrication isn't necessary to effect a seal, only to reduce friction and wear on moving parts.
An effective lubrication program should be established from experience with the valve for its
particular application and frequency of operation.
ORBIT's recommended lubrication schedule should be used as a minimum guideline.
All ORBIT Valves are equipped with an adjustable stem packing chamber which is required only if
a stem leak should develop.

1The first step is to
check the valve nameplate
for size, class and trim.
Size and class are also
marked on the body.
2Verify that the valve is
suitable for the service in
which it is being installed
by referring to the service
tag and nameplate.
3Check the handwheel
and position indicator rod
for possible damage.
4On flanged valves,
remove the flange
protectors and inspect the
flange facings for deep
nicks and scratches.
5On handwheel valves,
cycle fully open and fully
closed to check for ease of
operation.
Check indicator rod travel
against dimensions on
page 8 to verify
full stem travel.
6For valves equipped
with power actuators,
verify that a proper air
supply or electric power
source is available.
7For actuated valves
equipped with an
instrument package,
verify that all components
and piping are undamaged.
8After these points
have been checked and
approved, the valve is
ready for installation.

1Small valves
(as shown at right)
may be lifted or carried by
the handwheel without
damage to the valve.
2Larger valves should be
lifted by using the lifting
lugs provided, or by looping
a chain around bonnet as
shown at right.
3Never lift larger valves
by the handwheel.
Attempts to lift a large or
heavy valve in this fashion
can result in injury to
personnel and damage to
valve and property.
4During installation,
orient the valve so that the
preferred pressure end will
be toward the higher
pressure, when the valve
is closed.
5This will provide longer
valve life and easier
operation.
6The words preferred
pressure end have been
abbreviated to
“Pref. Pres. End”
and can be found stamped
on one end connection.
This stamping is marked
with red paint.
7When possible, ORBIT
valves should be installed
with the bonnet in a
vertical position.
When repairs are necessary,
consult your ORBIT
representative for details
on how to repair an ORBIT
valve without removing it
from the line.

can be bolted into the line
using standard studs and
nuts.

9ORBIT Block-and-Bleed,
or grease seal valves are
threaded for a fitting, but
are shipped with a pipe
plug to prevent damage to
the valve and/or fitting.
The pipe plug should now
be removed and replaced
with the proper fitting.
10 On threaded valves,
inspect the threads in both
ends of the valve to verify
no damage occurred during
shipment.
Be sure there is no dirt, grit,
or chips in the valve bore
or threads.
11 Apply a quality thread
compound to the threads
on the pipe.
12 Carefully align the
pipe and valve threads
and thread the valve
clockwise on the pipe.
13 Securely tighten with
a pipe wrench.
For safety, threaded piping
requires secure anchoring
of all components that are
screwed into threaded
valves.
14 For weld end valves
the temperature required
to weld the valve into the
line will exceed the rated
working temperature of
the valve.
ORBIT valves with Nylon or
Teflon seats are vulnerable
to damage by excessive
heat, so use the following
precautions.
15 Close the valve before
welding to protect the seat
and core face.
16 We recommend the
size of the weld rod never
exceeds 5/32 in. (4.0 mm)
diameter and the maximum
body temperature does not
exceed the valve rating
during welding.
17 When insulating low
temperature valves, do not
insulate above this line.
Insulating above this line
can result in injury to
personnel and damage to
valve and property.

packages are equipped
with lifting eyes.
These should be used
during installation to
prevent damage to the
unit and avoid injury to
personnel.
automated
2For valves equipped
with actuators not
manufactured by ORBIT,
use lifting eyes if present.
Otherwise, loop a chain
around the valve bonnet
to lift the unit.
3During installation
orient the valve so that
the preferred pressure end
will be toward the higher
pressure when the valve is
closed.
4This is important
because it reduces wear
and because the valve may
be rated at a different
working pressure when
installed in the opposite
direction.
5The words preferred
pressure end have been
abbreviated to
“Pref. Pres. End”
and are stamped on one
end connection.
It is marked with red paint
for easy identification.
6On piston actuated
valves, a gas over oil tank is
provided to assure smooth
operation and prevent
valve damage.
7The gas over oil tank
must be in the vertical
position when the valve is
installed.
Unless otherwise specified
at the time of order, the
gas over oil tank will be
mounted in this position.
8If your valve and
actuator package is to be
installed with the stem in
other positions, the gas
over oil tank must be
mounted vertically.
For example, in a
horizontal piping run.
Depending on valve and
actuator combination,
bracing may be required
to support actuator.

more information.
valves and
11 After the valve and
actuator unit has been
installed in the line, the
actuator power supply
should be connected.
12 IMPORTANT!
For pneumatic actuators
manufactured by ORBIT,
the supply pressure must be
regulated to the amount
shown on the nameplate.
Failure to comply with this
can damage the unit.
13 Unless otherwise
specified on the nameplate,
the minimum actuator
pressure should always be
within 5 psi, 0.3 bar of
maximum pressure.
14 Connect the opening
air supply for the
diaphragm actuator to the
bottom point A.
Connect the closing air
supply to the top point B.
15 The first step in
installing an ORBIT Piston
Actuated Valve is to check
the NAMEPLATE to
determine if the actuator is
the LG type or the LS type.
LG or LS will be the first
letters of the actuator
figure number.
For example,
LS-124-D-3-X-S.
16 If the nameplate is
illegible do not attempt to
install without consulting
an ORBIT Representative.

17 On LG type double
acting piston actuators, the
closing air supply is
connected to point Aand
the opening air supply is
connected to the top of the
gas over oil tank point B.
18 For LG type spring
close piston actuators the
opening air supply is
connected to the top of the
gas over oil tank point B.
On loss of air supply, the
actuator closes forcing the
oil into the tank.
19 The LS type piston
actuator is a new design
that reduces the size of the
gas over oil tank and allows
quicker operating times.
The opening air supply is
connected at point Aand
the closing air supply is
connected to the top of the
gas over oil tank point B.
20 For LS type spring
close piston actuator the
opening air supply is at
point A.
Failure to connect the
opening air supply to this
point will keep the actuator
from opening the valve.
21 Also on LS spring close
piston actuators the pipe
plug on top of the gas over
oil tank must be replaced
with the filter breather
supplied. Failure to do this
could keep the unit from
operating and result in
injury to personnel and
damage to valve, actuator
and property.
22 Most piston actuators
except those equipped with
a hydraulic open mechanism
will be the LS model.
The Double Acting piston
with a hydraulic open model
will continue to be the LG
type.
23 Cycle the valve fully
open and fully closed to
verify correct operation.
Check the indicator rod for
full travel. Rod travel
distance can be found on
page 8.
Check the instrumentation
for correct operation.
24 The valve and actuator
package is now ready for
operation.

POSITION INDICATOR REFERENCE CHART
On an ORBIT Actuator or an ORBIT Valve with a rising stem valve position
indicator, the indicator rod shows valve position. To determine if a valve, or
valve and actuator package is achieving full travel, measure the protruding
portion of the indicator rod in the closed position. Cycle the valve and measure
the indicator rod in the open position. Subtract to find valve travel.

1ORBIT valves will give
maximum performance and
long life when used with an
effective maintenance
program.
2Lubrication 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.
3The recommended
lubrication schedule and
types of grease are shown
at the top of this page.
4The 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.
5WARNING! 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.
6All 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.
(CONTINUED ON NEXT PAGE)
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.

7All 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.
8Remove 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.
9Thread 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.

20 All piston
actuators are quipped with
a gas over oil tank to assure
smooth operation and
prevent valve damage.
Proper fluid level is
important.
ORBIT
21 To check the fluid
level, read the nameplate to
determine if the actuator is
the LG type or the LS type.
If the nameplate is illegible
or missing DO NOT attempt
to check the fluid level
without consulting ORBIT
Representative.
15 ORBIT diaphragm
actuators equipped with a
manual close mechanism
have an additional upper
lube point located on the
manual closer stem. Spring
close diaphragm actuators
have no upper lube point.
16 Diaphragm actuators
equipped with a two way
manual mechanism have an
upper lube point that is
only accessible when the
manual mechanism is in the
open position.
17 All piston
actuators have a lower lube
point above pressure line
pressure.
ORBIT
18 ORBIT piston actuators
equipped with a manual
close mechanism have an
additional upper lube point,
which lubricates the manual
mechanism stem.
Piston actuators with a two
way manual mechanism
have no upper lube point.
19 Piston actuators
equipped with two way
gear mechanism have a
lube point on the gear box
as shown.
22 To check fluid level for
the LG type, CLOSE the valve.
This forces the hydraulic
fluid from the actuator into
the gas over oil tank.
In the closed position the
fluid should reach the level
indicated in the chart below.
If the fill plug is
removed in the OPEN position,
actuator pneumatic pressure will be
encountered if the system is under
pressure. Personal injury and/or
damage to property may result.

1All ORBIT valves except
O.S.&Y. bonnet design
utilize a hydraulic type
stem packing chamber.
Stopping stem leaks
promptly reduces damage
to the packing and the
valve.
Do not
remove packing fitting.
Personal injury and/or
damage to property may
result.
WARNING!
2Stem leaks are most
frequently associated with
start ups or other operating
changes, but some may
develop during steady
operation or after long use.
3To stop stem leaks,
advance or tighten the
packing adjustment screw.
This forces the plastic
packing past the ball check
into the packing chamber.
4As the plastic packing
is forced into the packing
chamber it increases the
pressure and reactivates the
Chevron type packing rings.
Usually 5 to 10 turns on the
adjustment screw will stop
the stem leak.
5Should the plastic
packing become depleted,
it can be replaced by
removing the packing
adjustment screw.
(This should be done slowly
and carefully to be sure the
ball check has sealed off the
packing chamber pressure.)
and replacing it with the
type of plastic packing that
is shown on the nameplate.
Do not substitute without...
6...consulting the chart
on page 17.
Replace the adjustment
screw and advance it to stop
the leak but do not exceed a
50 lb. pull on a 6 in. wrench
(20 kg pull on a 150 mm
wrench). A sufficient number
of threads in the packing
chamber must be left
exposed to allow
engagement of the packing
screw threads.
7DO NOT OVER PACK!
Over packing can result in
stiff handwheel operation
or can build up excessive
pressure in the stem
packing chamber, causing
forceful expulsion of the
entire packing fitting.
To prevent over packing
when the valve is in service,
do not exceed a 50 lb. pull
on a 6 in. wrench (20 kgs
pull on a 150 mm wrench).
8If the valve is not in
service, partially open the
valve and advance the
adjustment screw until the
handwheel will not coast
(freewheel) after being spun.
Do not exceed a 50 lb. pull
on a 6 in. wrench (20 kg pull
on a 150 mm wrench).

9WARNING! If the
valve has been over
packed - DO NOT TRY
TO REMOVE THE BODY
OF THE PACKING FITTING
to relieve the excessive
packing pressure. Injury
or damage could result.
The packing chamber
retains high pressure
even if the valve is not
in service.
10 Remove the packing
adjustment screw and gently
tap against the ball check
with a 1/8 in. pin punch.
This will allow the excessive
pressure to escape past the
ball check.
Wear safety glasses and
gloves and stand to the
side of the packing fitting
centerline while relieving
packing pressure.
11 ORBIT high
temperature valves feature
an adjustable type stem
packing made possible by
utilizing a deep stuffing
box, packing gland, and
gland flange retained with
adjustment bolts and nuts.
12 Effective sealing of
pressure by the stem
packing rings is maintained
by the compression applied
to the gland flange and
retainer bolts.
13 If a stem leak occurs,
more compression can be
applied by evenly adjusting
the hex nuts on the gland
retainer bolts. Too much
compression on the
retainer can cause the
stem to bind, making the
valve hard to operate.
14 WARNING! Never
completely remove the
hex nuts from the gland
retainer bolts while the
valve is in service and
under pressure.
Personal injury and/or
damage to property may
result.
15 For the packing
adjustment nuts to be
accessible on large bore
O.S.&Y. valves the cover
must be removed.
16 The stem packing will
not harden up to 800°F
(427°C).
This packing is very
effective, requires little
attention and is suitable for
steam, air, water, liquefied
petroleum, natural gas and
a variety of chemicals.

3The special lube fitting
on top of the valve is in the
valve pressure area so use
these precautions:
AAttach a grease gun with
out-put higher than line
pressure to the fitting.
BBack out the shut-off-
screw 2 to 3 turns ONLY.
CPump in 1 to 2 lbs., 0.5 to
1 kg., of lithium base
grease, and if possible
cycle the valve to evenly
distribute the lubricant.
DTighten the shut-off screw securely before removing the pump.
The stem lube point “A” use a standard hydraulic lube fitting.
Pump two or three times.

1ORBIT Drilling Valves
are designed for holding
pressure in one direction
only. They must be installed
so that the greater amount
of pressure will be applied
to the preferred pressure
end. Damage to valve may
result if not installed
properly.
2If pressure could drop
below 100 psi in the closed
position, USE THE STEM
LOCKING DEVICE to prevent
the valve from opening. To
use the Stem Locking
Device, tighten the lock
screw in the packing gland,
which forces a brass friction
plug against the valve stem.
4The conventional
type Packing Gland
Assembly uses braided
packing rings and gland
studs with nuts. Adjustment
is identical to O.S.&Y. valves
shown on page 16,
steps 11 to 15.
