ENGINEERED VALVES

Scope
One of the most trusted valves in the petroleum
industry, the CAMERON T31 Fully Welded Body Ball
Valve combines the strength of forged components
with a lightweight and compact spherical design.
CAMERON T31 Fully Welded Body Ball Valves
satisfy ASME 150 through 2500 (PN 20 through
PN 420) and API 2000 through 10000 standards.
Made of forged steel to assure uniform fine grain
structure and toughness, they may be specified
in sizes from 2" to 56" (DN 50 to DN 1400).

Engineered for heavy-duty service and minimal
maintenance, the CAMERON T31 Fully Welded
Body Ball Valve is commonly selected for a
number of applications. The distinctive design of
the CAMERON T31 Fully Welded Body Ball Valve
gives it maximum strength and minimum weight
as well as maximum resistance both to pipeline
pressure and stresses. The compact, spherical
design also eliminates body flanges, thus reducing
overall size and leak paths.

Storage
The valves are conditioned for a storage period of
approximately six months. The following care should
be taken when storing valves.
1. Make sure the valve end connection covers remain
in place during storage.
2. If the valve does not have an operator already
installed and the valve will be stored outside, the
open stem extension or the stem adapter should
be covered to avoid water buildup.

Installation, Operation and Maintenance Manual

3. If long-term storage is required, the valve
should be conditioned using a corrosion
inhibitor and end connection covers.
Follow the guidelines found in CAMERON
Engineering Bulletin 476B for long term
storage.
Obtain a copy from your Cameron Valves &
Measurement representative.

Installation
Handling of Valves
1. The valve should be lifted in such a way that
the body supports the load.
CAUTION: The journal and the end connection
necks are suitable places to attach lifting
slings. Never use handwheels or other
protruding parts of the gearbox or actuator
not designated for this purpose.
2. If the valve is equipped with lifting lugs, these
should be used for handling.
3. The end protector covers should be kept in
place on the end connections during all
handling. Remove only during final installation
of the valve.

Figure 3 - Correct valve lifting using End Connection Necks.

EQUALIZING YOKE

CAUTION: During handling, protect the end
connection faces and fittings against damage
from the lifting devices. Failure to cover faces
and fittings could cause damage to the valve.

Position of Valve
The ball valve may be installed in any position.
Either end of the valve may be installed as the
upstream end.

Protection of Ball
CAUTION: The ball should be fully open
during the installation of the valve. Failure to
keep the ball fully open during installation
could cause damage to the valve.
If the ball must remain in the closed position
during installation of the valve, coat the
exposed surfaces of the ball with grease.
This will protect the plug from damage due to
weld splatter.
CAUTION: Do not leave the valve in the
partially open position for an extended
period of time.

Installation, Operation and Maintenance Manual

Figure 4 - Correct lifting using the valve Lifting Lugs.

CAUTION: A weld end valve without pup pipes
should never be installed in the closed position.

Welding Instructions
When preheating, welding or stress relieving, body
temperatures must not exceed 400°F (200°C) at
any point beyond 3" (75 mm) from the weld.
Use tempil sticks to check temperatures. Before
CAMERON T31 Fully Welded Body Ball Valves are
welded into final position in the pipeline, cover the
valve seal areas (ball-to-seat area and seat-to-end
connection area) with 1" wide masking tape from
the 3 o'clock to the 9 o'clock position. This will help
prevent any foreign material from becoming lodged
in these areas. The piping system should also be
pigged before operation or pressure testing to
remove any foreign material from the pipeline.

Hydrostatic Testing
2. Depending on the valve stem and the actuator/
gear mounting kit, it is possible that the actuator
may be installed in multiple positions. If this is
the case, determine where the customer desires
the handwheel or actuator control panel and
install it accordingly. (A thin layer of antiseeze on
the valve stem is recommended.)
3. Once the operator is mounted, secure it with the
appropriate bolts. If the bolt holes do not line up,
slightly operate to the open or closed to match
the mounting flange. If you are unable to operate
the operator, performing steps 2 and 3 of Setting
Stops may need to be conducted.
4. It is now necessary to set the operator stops as
outlined in the following section.

Setting Stops
Gear Operator with Stops
1. Make sure that operating the valve to the fully
open and fully closed position will not disrupt
current operation of line.
2. Loosen the open and closed stop screw locknuts.
3. Turn stop screws counter-clockwise to increase
gear travel.
4. Operate the valve to the fully open position.
5. Utilize the stem stop viewports to verify valve
position. (Refer to Open and Closed Viewports
on page 6.)
6. Turn the open stop screw clockwise until it stops,
then tighten the locknut. If the stop screws will
not turn, repeat steps 3 and 4.
7. To set the closed stop, conduct steps 3 - 6,
operating the valve to the closed position and
utilize the closed stop.

LOCKNUT

Mounting the Gear/Actuator
To mount a gear or power operator on a valve, use
the following guidelines. Note: The guidelines
given are for typical gear and actuator designs.
Specific instructions for each design should be
obtained from the gear / actuator manufacturer.
1. Make sure the valve is in the fully open or closed
position and position the actuator to match.

When CAMERON T31 Fully Welded Body Ball Valves
are installed in a piping system that requires hydrostatic
testing of the adjoining pipe, follow these procedures
to minimize any damage that could occur to the
sealing surfaces and seat seals inside the valve.
1. Valve should be in the fully open position when
the injection of test fluid begins. This will allow
any pipeline debris to be flushed through the
valve bore and out of the piping.
2. Once the piping system has been purged of
debris and the system has been filled completely
with the test fluid, the ball valve should be placed
in the partially open position (approximately 10°
from the fully open position). This allows test
fluid into the body cavity of the valve.
3. The valve is now ready to be pressure tested.
4. Upon completion of hydrostatic testing, the valve
should be returned to the fully open position
before removing the test fluid from the piping
system. The test fluid in the body cavity can be
drained through the body drain port located on
the lower portion of the valve body.
5. Once the valve and piping system have been
pigged and customer product is injected into the
piping system, the valve should be moved to the
partially open position (approximately 10° from
the fully open position). Any remaining test fluid
trapped in the valve body cavity can then be
vented through the body bleed plug, located on
the lower portion of the valve body. If the valve
has been fitted with a stem extension, the vent
fitting will be located below the mounting flange
on top of the extension.
6. Opening the body bleed fitting will force trapped
test fluid out of the body cavity. Keep the bleed
plug open until all fluids have been exhausted
through the body bleed plug.
7. Close the valve body bleed fitting and return the
valve to the fully open position or the required
operating position.
8. The valve seat pockets should be filled with an
approved valve flush product to displace any
test fluid. Refer to Routine Seat Cleaning which
appears on page 7.

2. Loosen the open and closed stop screw locknuts.
3. Turn stop screws clockwise to increase travel.
4. If equipped with a manual override, use it to
operate the valve to the fully open position.
5. Check the stem stop viewports to verify valve
position. (Refer to Open and Closed Viewports
on page 6.)
6. Turn the open stop screw counter-clockwise until
it stops and tighten the locknut.

CAUTION: Once the stop makes contact with
the vane, do not continue to turn the screw.
Continuing to turn the screw could move the
valve off the stops.
7. If the stop screws will not turn repeat steps 3
and 4.
8. To set the closed stop, repeat steps 3 - 6,
operate the valve to the closed position and use
the closed stops.

Open and Closed Viewports
Once the pipe plug and relief plug are removed from the valve mounting flange, the position of the keyshaft
stop relative to the valve stops can be observed on valves with nominal stem sizes of 3" and larger.
The valve is fully opened when the keyshaft stop butts against the valve stop as viewed through the
"open viewport" and is fully closed when the keyshaft stop butts against the valve stop as viewed through
the "closed viewport".
Figure 8 shows the viewport locations for valves with a 3" stem size and figure 9 shows the viewport locations
for valves with 4" and larger stem sizes.

Operating Times

Maintenance

Quick Operating Time
Opening or closing a valve quickly induces loads in
addition to the normal torsion load. It is therefore
necessary to limit valve operating times in order to
prevent over stressing of the valve.
Valves can be safely operated with an operating
time given by the formula:

The CAMERON T31 Fully Welded Body Ball Valve
requires a minimum of maintenance. In order to
optimize the life of the valve, the maintenance
procedures on pages 6 and 7 should be followed.

*Quick operating time =

Valve nominal bore
2

If a faster operating time is required, please call your
Cameron Valves & Measurement Representative.

Operation
Operating the valve is an important part of routine
maintenance. Operation of the valve will help to
break-up any buildup on the seat face and/or ball
and, if so equipped, will rotate the seat rings 15°,
distributing the wear on the insert.

Longest Operating Time
When the valve is being operated, the seat face is
exposed. Therefore, to minimize the amount of time
in which the seat face is exposed, Cameron Valves
& Measurement group recommends a maximum
operating time as follows:
*Longest Operating Time = 5 x Valve nominal bore
(i.e., one minute
per foot of nominal
bore)
*The time is in seconds and the bore size is in inches.
CAUTION: Failure to follow these operating times
could cause damage to the valve.

ENGINEERED VALVES

Double-Block-and-Bleed
Whether in the open or closed position, pressure
on each side of the ball is blocked from the body
cavity by the seat ring. The body cavity can then
be blown down or drained through the body port.
Take the following steps when block-and-bleeding
a valve:
WARNING: Make sure proper safety garments
are worn, and follow all customer safety
procedures. Failure to do so could injure
you or others.
1. The CAMERON bleed fittings have one or two
exhaust ports. You should be aware of their
orientation. Any debris in the valve or fitting
will be exhausted at a high velocity.
2. If necessary, tighten the fitting to reorient the
exhaust ports.
3. With the valve fully open or fully closed, open
the bleed fitting all the way. When opening the
bleed fitting, a backup wrench may be used to
prevent accidental removal of bleed fitting.
The process of block-and-bleeding the valve is
intended to test the valve integrity.
If the valve does not blow down, this indicates that
the seats are leaking. Consult the Troubleshooting
section.

WARNING: Never try to block-and-bleed the
valve in the partially open position.
Failure to do so could injure you or others.

Figure 13 - Cameron T31 Seat Section.

Seat Cleaning

Gear Maintenance

The seat pocket area is the primary area where
any valve can be affected by contaminants in
the lines. To insure the seat's free movement,
it is recommended that the valve seat pockets
be cleaned routinely with an approved product.
(The frequency of routine cleaning depends
on the severity of service, but once a year is a
good guideline. Contact your Cameron Valves &
Measurement group representative for assistance).
Cleaning procedures can be found on page 10.

The following gear maintenance should be
performed along with the valve maintenance:
1. Inspect housing for damage and wear.
2. Inspect weather seal and replace, if damaged.
This will prevent water from entering the
gearbox and causing corrosion.
3. Lubricate gear, using an approved lubricant.
