1 GENERAL
1.1 Scope of the manual
This installation, operation and maintenance manual provides
essential information on trunnion mounted XG/XM series ball valves.
The actuators and instrumentation to be used with these valves are
also discussed briefly. Refer to the separate actuator and control
equipment instruction manuals for further information.
1.2 Valve description
Trunnion mounted XG/XM series valves are flanged full bore ball
valves. The valve body is in two parts, fastened together by body-
joint bolting. The ball and shaft are separate. Shaft blow-out is
prevented by bonnet and a shoulder machined on the shaft.
The valve is either soft or metal seated. Shaft torque is transmitted to
the ball through a splined bore in the ball.
The valve is 1-way or 2-way tight depending on the seat construction.
Tightness direction is shown with an arrow on 1-way valves.
Construction details of individual valves are included in the type code
shown on the valve identification plate. To interpret the type code,
please refer to the type coding key in this manual.
Trunnion mounted XG/XM series ball valves are specially designed
for demanding throttling and shut-off service with high pressure
differentials.
1.3 Markings
Body markings are cast or stamped on the body (see Fig. 2).
The identification plate (Fig. 3) is attached to the flange.
Identification plate markings are:
1. Body material
2. Shaft material
3. Trim material
4. Seat material
5. Max and min operating temperature
6. Max shut-off pressure differential / temperature
7. Pressure class
8. Type designation
9. Valve manufacturing parts list no.
10. Model
NOTE:
Selection and use of the valve in a specific application requires
close consideration of detailed aspects. E.g. Q2G-trim is for
relatively clean gas applications, note possibility of clogging. Due
to the nature of the product, this manual cannot cover all the
individual situations that may occur when installing, using or
servicing the valve.
If you are uncertain about use of the valve or its suitability for your
intended purpose, please contact Neles for more information.
For valves in oxygen service, please see also the separate
installation, maintenance and operating instructions for oxygen
service (see Neles document id:10O270EN.pdf)

CAUTION:
Do not exceed the valve performance limitations!
Exceeding the limitations marked on the valve may cause
damage and lead to uncontrolled pressure release.
Damage or personal injury may result.
CAUTION:
Do not dismantle the valve or remove it from the pipeline
while the valve is pressurized!
Dismantling or removing a pressurized valve will result in
uncontrolled pressure release. Always isolate the relevant part of
the pipeline, release the pressure from the valve and remove the
medium before dismantling the valve. Be aware of the type of
medium involved. Protect people and the environment from any
harmful or poisonous substances. Make sure that no medium can
enter the pipeline during valve maintenance.
Failure to do this may result in damage or personal injury.
CAUTION:
Beware of the ball cutting movement!
Keep hands, other parts of the body, tools and other objects out of the
open flow port. Leave no foreign objects inside the pipeline. When the
valve is actuated, the ball functions as a cutting device. Close and
detach the actuator pressure supply pipeline for valve maintenance.
Failure to do this may result in damage or personal injury.
CAUTION:
Beware of noise emission!
The valve may produce noise in the pipeline. The noise level depends
on the application. It can be measured or calculated using the Neles
Nelprof computer program.
Observe the relevant work environment regulations on noise emission.
CAUTION:
Beware of extreme temperatures!
The valve body may be very hot or very cold during use.
Protect people against cold injuries or burns.
CAUTION:
When handling the valve or the valve package, bear in mind
its weight!
Never lift the valve or valve package by the actuator, positioner,
limit switch or their piping. Place the lifting ropes securely around
the valve body (see Fig. 7). Damage or personal injury may result
from falling parts.
The weights are shown on pages 13–15.
CAUTION:
Follow the proper procedures when handling and servicing
oxygen valves.

1X72EN - 9/2020 5
2 TRANSPORTATION,
RECEPTION AND STORAGE
Check the valve and the accompanying device for any damage that
may have occurred during transport.
Store the valve carefully. We recommend storing indoors in a dry
place.
Do not remove the flow port protectors until installing the valve.
Move the valve to its intended location just before installation.
The valve is usually delivered in the open position.
3 INSTALLATION AND USE
3.1 General
Remove the flow bore protectors and check that the valve is clean
inside. Clean the valve if necessary.
3.2 Installing in the pipeline
Flush the pipeline carefully before installing the valve. Make sure the
valve is entirely open when flushing. Foreign particles, such as sand
or pieces of welding electrode, will damage the ball and seats
.
The valve may be installed in any position and offers 1-way or 2-way
tightness, see Sections 1.2 and 1.4. However we do not recommend
installing the valve with the actuator on the underneath side because
dirt in the pipeline may then enter the body cavity and damage the
gland packing. The position to be avoided is shown in Fig. 8.
It may be necessary to firmly support the pipeline in order to protect
the valve from excess stress. Sufficient support will also reduce
pipeline vibration and thus ensures proper functioning of the
positioner.
To facilitate servicing, it is preferable that the valve be supported by
the body, using pipe clamps and supports. Do not fasten supports to
the flange bolting or to the actuator, see Fig. 9.
Fig. 6 Storing the valve
Fig. 7 Lifting the valve
CAUTION:
When handling the valve or the valve package as a whole, bear in
mind the weight of the valve or the entire package!
CORRECT
WRONG
NOTE:
Use screws, nuts, bolts and gaskets equivalent to the
fasteningsused elsewhere in the pipeline. Center the flange
gaskets carefully when fitting the valve between flanges.
NOTE:
Do not attempt to correct pipeline misalignment by means of
flange bolting.
Fig. 8 Avoid this mounting position
Fig. 9 Supporting the valve

61X72EN - 9/2020
Valve insulation
If necessary, the valve may be insulated. Insulation must not continue
above the upper level of the valve body, see Figure 10.
3.3 Actuator
The valve open/closed position is indicated as follows:
• by an indicator on the actuator
or
• by a groove at the end of the ball shaft (parallel to the ball flow
opening).
If there is any uncertainty about the indicator, check the ball position
by the groove.
The actuator should be installed in a manner that allows plenty of
room for its removal.
The upright position is recommended for the actuator cylinder.
The actuator must not touch the pipeline, because pipeline vibration
may interfere with its operation.
In certain cases it may be considered advantageous to provide
additional support to the actuator. These cases will normally be
associated with large actuators, extended shafts, or where severe
vibration is present. Please contact Neles’ business for advice.
3.4 Commissioning
Ensure that there is no dirt or foreign objects left inside the valve or
pipeline. Flush the pipeline carefully. Make sure that the valve is
entirely open when flushing.
Ensure that all nuts, pipings, and cables are properly fastened.
Check that the actuator, positioner, and switch are correctly adjusted.
Actuator adjustment is explained in Section 6. To adjust the
accompanying device refer to the separate control equipment
instruction manuals.
4 MAINTENANCE
4.1 Maintenance general
Although Neles valves are designed to work under severe conditions,
proper preventative maintenance can significantly help to prevent
unplanned downtime and in real terms reduce the total cost of
ownership. Neles recommends inspecting the valves at least every
five (5) years. The inspection and maintenance interval depends on
the actual application and process condition. The inspection and
maintenance intervals can be specified together with your local Neles
experts. During this periodic inspection the parts detailed in the Spare
Part Set should be replaced. Time in storage should be included in
the inspection interval.
Maintenance can be performed as presented below. For
maintenance assistance, please contact your local Neles office. The
part numbers in the text refer to the exploded view and to the parts
list in Section 10, unless otherwise stated.
4.2 Changing the gland packing
while the valve is in the
pipeline
The V-ring gland packing requires no regular tightening. The gland
packing tightness is provided by the pipeline pressure together with
gland pressure against the packing rings. In graphite gland packings,
tightness is ensured by contact between the gland follower and the
packing rings.
The gland packing (69) must be changed if leakage occurs even after
the hex nuts (18) have been tightened. The V-ring gland packing

NOTE:
When installing the actuator on the valve, make sure that the
valve package functions properly. Detailed information on
actuator installation is given in Section 6 or in the separate
actuator instructions.
Insulation limit
CAUTION:
Observe the safety precautions mentioned in Section 1.8 before
maintenance!
CAUTION:
When handling the valve or the valve package as a whole, bear in
mind the weight of the valve or the entire package!
NOTE:
When sending goods to the manufacturer for repair, do not
disassemble them. Clean the valve carefully and flush the valve
internals. For safety reasons, inform the manufacturer of the type
of medium used in the valve (include material safety datasheets
(MSDS)).
NOTE:
In order to ensure safe and effective operation, always use
original spare parts to make sure that the valve functions as
intended.
NOTE:
For safety reasons, replace pressure retaining bolting if the
threads are damaged, have been heated, stretched or corroded.
CAUTION:
Do not dismantle the valve or remove it from the pipeline while
the valve is pressurized!

1X72EN - 9/2020 7
must be tightened with care because excess force may damage the
V-rings.
• Make sure that the valve is not pressurized.
• Detach the actuator and bracket according to the instructions in
Section 4.4.
• Remove the key (10).
• Remove the nuts (18), the disc spring sets (150) and the gland
(9).
• Remove old packing rings (69). Do not damage the surfaces of the
packing ring counterbore and shaft.
• Clean the packing ring counterbore.
• Place the new packing rings (69) over the shaft (5). The gland fol-
lower may be used for pushing the rings into the counterbore. Do
not damage packing rings in the shaft keyway. See Fig. 11 for
proper orientation.
• Pre-compress the packing rings first either by tightening the
gland nuts (with or without disc springs) to the torque Tt or by
tightening the gland with disc springs to the height H2. See Fig.
11 and the value from Table 1.
• Carry out 3…5 operation cycles with the valve. Suitable range of
movement is about 80 %.
It is not necessary to fully close or open the valve during the
operation.
• Loosen the gland nuts. Place the disc spring sets (150) on the
gland studs as applicable. Retighten the nuts (18) to the torque Tt
or so that the disc springs are compressed to the height H2, see
Table 1.
• If the leakage still occurs when the valve is pressurized, re-
tighten the nuts but don't exceed the value in the Table 1 by 50 %
or do not fully compress the disc springs.

4.3 Repair of a jammed or stuck
valve while it is in the pipeline
Jamming may be due to the ball (3) and seats (7) becoming clogged
with flow medium. They may be cleaned by turning the ball to the
partly open position and flushing the pipeline. If this does not help,
follow the instructions in the following sections.
4.4 Detaching the actuator
It is generally most convenient to detach the actuator before
removing the valve from the pipeline. If the valve is small or if it is
difficult to access, it may be more practical to remove the entire
package at the same time.
• Close and detach the actuator pressure supply pipeline and
remove control cables.
• Unscrew the bracket screws.
• Detach the actuator. The actuator can be removed by hand or
with a special tool made for this purpose. The tool can be ordered
from the manufacturer (see Section 8 “Tools”).
• Remove the bracket.
4.5 Removing the valve from the
pipeline
• Make sure that the valve is not pressurized and that the pipeline
is empty. Make sure that the medium cannot flow into the section
where servicing is to take place.
• Support the valve carefully with a hoist. Place ropes carefully and
unscrew the pipe flange bolts. See that the ropes are positioned
correctly, see Fig. 7. Lift valve down.
4.6 Dismantling the valve
• Place the valve in a standing position on the pipe flange end. Use
a level surface that will not scratch the flanges. See that the body
stud nuts (16) are facing upward.
• Mark the the body halves for correct orientation during re-assem-
bly.
• Turn the ball to the closed position.
• Remove the key (10).
• Unscrew the gland nuts (18). Remove the disc spring sets (150)
and the gland (9).
• Unscrew the body stud nuts (16).
• Remove the body cap (2). If the seat (7) is not lying on the ball
(3), prevent the seat from falling from the body cap and detach it
later. Don’t leave your fingers between the body cap and the
surface!
Stand the removed body cap on its pipe flange.
• Remove the seat (7) from body cap (2) if it is still in place.
• Unscrew the bonnet stud nuts (17). Remove the shaft (5) and
bonnet (8). Knock the bonnet off with a piece of wood and a ham-
mer, if needed.
• Lift the ball (3) along with the trunnion plates (89)out of the body
(1) Handle the ball carefully and place it on a soft surface.
• Remove the seat (7) from the body (1).
• Remove the trunnion plates (89) from the hubs of the ball.
• Remove the trunnion bearings (99) and the bearing spacers (91)
from each trunnion.
• Push the shaft out of the bonnet.
• Remove thrust bearings (70, 71) from the shaft and packing rings
(69) from the bonnet (8).
• Remove the body gasket (65) and the bonnet gasket (66).
4.7 Inspection of removed parts
• Clean removed parts.
• See if the shaft (5) or bearings (70, 71, 99) are damaged.
• See if the ball (3) or seats (7) are damaged (scratched), by exam-
ining them under bright light. The ball and the seat can be
replaced if necessary.
• See if the body joint sealing surfaces are damaged.
4.8 Replacing parts
We recommend that soft material parts be replaced whenever the
valve is dismantled for servicing. Other parts may be replaced if
necessary. Always use genuine spare parts to ensure proper
functioning of the valve (see section “Ordering spare parts”).
CAUTION:
When handling the valve or the valve package as a whole, bear in
mind the weight of the valve or the entire package!
CAUTION:
Do not detach a spring-return actuator unless a stop-screw is
carrying the spring force!
NOTE:
Before dismantling, carefully observe the position of the valve
with respect to the actuator and positioner/limit switch so as to
make sure that the package can be properly re-assembled.
Fig. 12 Removing the actuator with an extractor
CAUTION:
Do not dismantle the valve or remove pipeline while the
valve is pressurized!

1X72EN - 9/2020 9
4.9 Re-assembly of the valve
• Place the valve body (1) and the body cap (2) on the pipe flange
end. Use a level surface that will not scratch the flanges.
Pre assembly of the seats
S and T seats:
Check the sealing surfaces.
• Place the back seal (O-ring) (63) into the groove in the seat. See
Figures 13 and 14.
• Place the back-up rings (64) made of PTFE strips at the side of
the O-ring. To ensure that the seam becomes flexible, the strip
must have slanted ends.
• For easier assembly, lubricate the O-ring and backup ring sur-
faces facing the seats with silicone grease or another suitable
substance. Please ensure the compatibility with the flow medium.
• Place the spring (62) into the groove in the seat (7). Connect the
ends of the spring.
• Place the seats into the body and body cap by hand or if neces-
sary, using a plastic mallet. The seat is in correct position when
the spring touches the body shoulder.
D and B seats:
K and G seats:
H seats:
• Check the sealing surfaces.
• Place the back seal (63) into the seat (7). See Figure 18.
• Place the seat into the body counterbore.
L seats:
L seats:
• Measure the 0-torque of the valve. It should be acc. to Table 2.
0-torque shall be adjusted with graphite plate rings (available
thicknesses are 0.2, 0.5 and 1.0 mm).
Table 2 0-torques
Roughness of the surfaces in contact with graphite back seals shall
be Ra 0.4 or better. Sharp edges shall be rounded off. Apply a thin
and even layer of molybdenum grease spray on cleaned ball and
seat surfaces before assembly.
• Place the O-ring (63) and the back up rings (64) into the grooves
of the ball seat (7) and lubricate them with silicone grease.

• Place the pre-compressed graphite rings (back seals)(195) onto
the seat.
• Place seal ring (braided graphite) (129) into the groove of the ball
seat.
• Place the ball seats into the body and the body cap using plastic
or wooden mallet or if necessary, using a hydraulic press.
All versions:
• Place a trunnion bearing (99) into each trunnion plate (89) coun-
terbore.
• Place a bearing spacer (91) over each ball trunnion.
• Fit a trunnion plate over each ball trunnion until the plate rests
against the bearing spacer (91). This operation must be per-
formed with care and without excessive force or the bearing will
be damaged. It may be necessary to tap the plate on with a plas-
tic mallet.
• Align the trunnion plates (89) relative to the ball port in the closed
position.
• With the ball (3) in the "closed" position, lower the ball/trunnion
plate subassembly into the body (1). NOTE: This procedure is
critical and careful attention is a must. The outside diameter of
the trunnion plates must pilot in the body counterbore. Carefully
lower the subassembly until a trunnion plate enters the counter-
bore (Usually one trunnion plate will enter the counterbore and
the other will be out of position.) Use a plastic mallet or a block of
wood to rotate the second trunnion into position. Once trunnion
plates are aligned, lower the subassembly until the trunnion
plates are seated in the bottom of the counterbore.
• Slide the thrust bearings (70=thinner, 71=thicker) over the shaft
(5). See the exploded view for proper orientation.
• Insert shaft subassembly through the bonnet (8) and install pack-
ing (69). Refer to Fig. 11 for proper orientation of packing.
• Install the gland (9) over shaft (5) and gland studs. Install the disc
springs sets (150) and the gland stud nuts (18) on studs and
tighten "finger tight."
• Install the bonnet gasket (66) and the bonnet subassembly over
the bonnet studs (10). Note the correct shaft position! Lubricate
the threads of studs (13) and tighten the nuts (17) according to
values in Table 2.
• Install the body gasket (65) in the body groove.
• Place the body cap (2) carefully over the body studs (12) and the
body (1). See that the flange holes are aligned acc. to the mark
made during the dismatling. Take care not to damage the body
gasket and the seat (7) in the body cap.
• Fasten the body nuts (16). Tighten the nuts gradually, always
switching to other side of the valve after every nut. The recom-
mended torques are given in Table 2. The flange faces must in
even contact with each other.
• Mount the key (10).
• Cycle the valve slowly a couple of times to insure correct position
of the ball between the two seats.
Tightening torques of the body joint bolting
• Tighten the gland nuts (18) acc. to Section 4.2 . Pull on the shaft
(5) while tightening to assure that shaft and thrust bearings are
always in contact with the body. Check for leakage once the
valve is pressurized..
• Install the valve in the pipeline as carefully and accurately as
when removing it. Follow the instructions given in Section 3.
5 TESTING THE VALVE
We recommend that the valve body be pressure tested after the
valve has been assembled.
The pressure test should be carried out in accordance with an
applicable standard using the pressure rating required by the
pressure class or flange drilling of the valve. The valve must be in an
half-open position during the test.
If you also want to test the tightness of the closure member, contact
the manufacturer.
NOTE:
The shaft will fit into the ball in one position only. There’s a larger
cog in the splined shaft or added cog in square end shaft and a
matching groove in the ball shaft bore. It is essential to note the
groove’s position during the next assembly step.

6 INSTALLING THE
ACTUATOR
6.1 General
Different Neles actuators can be mounted using suitable brackets
and couplings. The valve can be actuated by an M-handwheel
operator or B1-series actuators.
6.2 Installing the M-handwheel
operator
• The mark at the end of the shaft indicates the direction of the ball
flow bore. Turn the valve to the closed position.
• Lubricate the grooves of the actuator and the couplings. Place
the coupling on the shaft and lock it. Place the bracket on the
valve and turn the lubricated screws a few times.
• Turn the actuator to the closed position and push it carefully onto
the valve shaft on which the coupling has been mounted. Please
note the marks on the handwheel and the coupling.
• Lubricate the actuator screws. Tighten all screws.
• Adjust the ball open and closed positions with the hexagon
screws located at the side of the housing (see Figure 17). The
stop-screw for the open position is nearest to the handwheel on
the side of the housing and the screw for the closed position is at
the opposite end. The turning directions for the handwheel are
marked on the wheel.
• Check the handwheel by turning the valve to the extreme
positions. The yellow arrow should indicate the direction of the
ball flow bore.
6.3 Installing the B1C-series actuator
• Turn the valve to the closed position and drive actuator piston to
the extreme outward position.
• File off any burrs and clean the shaft bore.
• The line at the end of the shaft indicates the direction of the ball
flow bore.
• Lubricate the actuator shaft bore. Fasten the bracket loosely to
the valve.
• Slip the actuator carefully onto the valve shaft. Avoid forcing it
since this may damage the ball and seats. We recommend
mounting the actuator so that the cylinder is pointing upwards.
• Position the actuator parallel or vertical to the pipeline as
accurately as possible. Lubricate the actuator mounting screws
and then fasten all screws.
• Adjust the ball open and closed positions by means of the
actuator stop screws located at both ends (see Fig 18). An
accurate open position can be seen in the body flow bore. Check
that the yellow arrow on the actuator indicates the ball flow
opening position. Keep fingers out of the flow bore!
There is no need for stop screw adjustment if the actuator is re-
installed in the same valve. Drive actuator piston to the housing end
(open position). Turn the actuator by hand until the valve is in the
open position. Fasten the actuator in this position as explained
above.
• Check the stop screw thread tightness. An O-ring is used for
sealing.
• Check that the actuator is functioning correctly. Drive the actuator
piston to both cylinder ends and check the ball position and its
movement with respect to the actuator (close: clockwise; open:
counterclockwise). The valve should be closed when the piston is
in the extreme outward position.
• If necessary, change the position of the actuator pointing cover to
correctly indicate the valve open/closed position.
6.4 Installing the B1J-series actuator
Spring-return actuators are used in applications where valve opening
or closing movement is needed in case the air supply is interrupted.
The B1J type is used for spring-to-close operation; the spring pushes
the piston towards the cylinder end, the extreme outward position. In
turn, the B1JA type is used for spring-to-open operation; the spring
pushes the piston towards the housing. Spring-return actuators are
installed in a manner similar to B1C-series actuators, taking into
account the following.
B1J type
• Install the actuator so that the piston is in the extreme outward
position. The cylinder must not be pressurized and air supply
connections must be open. The valve must be in the closed
position.
B1JA type
• Install the actuator so that the piston is in the cylinder end
position at housing side. The cylinder must not be pressurized
and air supply connections must be open. The valve must be in
the open position.
The rest of the installation procedure is the same as in Section 6.3.
CAUTION:
Beware of ball cutting movement!

The following Table 4 lists malfunctions that might occur after
prolonged use.
Table 3 Trouble shooting
8 TOOLS
In addition to standard tools, the following special tools might be
needed.
• For removal of the actuator:
- extractor (ID-code table in actuator's IMO)
This tool can be ordered from the manufacturer. Always give the
valve type designation when ordering.
9 ORDERING SPARE PARTS
When ordering spare parts, always include the following information:
