1 GENERAL
1.1 Scope of the manual
This manual provides essential information on series GM-
Omega multistage trim installed sliding stem valves.
Actuators and positioners are only discussed briefly. Refer
to the individual manuals for further information on their
installation, operation and maintenance.
1.2 Valve construction
Series GM-Omega multistage trim valves are flanged (weld
end available) single seated sliding stem control valves. The
valve seat ring and retainer and plug with stem is a module
accessible through the bonnet opening (top entry) of the
body.
Our standard design provides a cage guide with a piston
type plug with a quick change seat ring. The two split cages
(cage guide and multistage cage) and inserted plug seal
ring makes strong support to ensure valve alignment.
For few cases in very small rated Cv, a unbalanced
contoured trim is used in this series.
This series is available with series of reduced Cv trims and
the standard seat tightness is class III~IV, optional trims can
meet to class V, ANSI/FCI 70-2.
The detailed structure is revealed by the type code shown
on the valve identification plate. The type code is explained
in Section 11.

is supplied with the valve. In addition, separate recycling
and disposal instructions are available from the
manufacturer. A valve can also be returned to the
manufacturer for recycling and disposal for a fee.
NOTE:
Selection and use of the valve in a specific application
requires close consideration of detailed aspects. Due to
the nature of the product, this manual cannot cover all the
individual situations that may occur when the valve is
used.
If you are uncertain about use of the valve or its suitability
for your intended purpose, please contact Metso for more
information.

1.7 Safety precautions 2 TRANSPORTATION, RECEPTION AND
STORAGE
Check the valve and the accompanying devices for any
damage that may have occurred during transport.
Store the valve carefully before installation, preferably
indoors in a dry place.
Fig. 3 Lifting the valve
Do not remove the flow port protectors until immediately
before installation of the valve into the pipeline.
The valve is delivered in the closed position. A valve
equipped with a spring-return actuator is delivered in the
position determined by the spring.
3 VALVE INSTALLATION
3.1 General
Remove the flow port protectors and check that the valve is
clean inside.
3.2 Installation into the pipeline
3.2.1 Pipeline cleaning
Make sure no foreign particles, such as sand or pieces of
welding electrode, are in the pipeline, they may damage
the sealing surfaces.
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 pressurised!
Dismantling or removing a pressurised 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 yourself
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 plug movement!
Keep fingers, 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 plug 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:
Protect yourself from noise!
The valve may produce noise in the pipeline. The noise
level depends on the application. It can be measured or
calculated using the Metso Nelprof software. Observe the
relevant working environment regulations in terms of
noise emission.
CAUTION:
Beware of a very cold or hot valve!
The valve body may be very cold or very hot during use.
Protect yourself against cold injuries or burns.
CAUTION:
When handling the valve or the control valve
assembly, take its weight into account!
Never lift the valve or control valve assembly by the
positioner, the limit switch or their piping.
Place the lifting ropes securely around the valve body (see
Fig. 3). Damage or personal injury may result from falling
parts.
CAUTION:
Follow the proper procedures when handling and
servicing Oxygen valves.
NOTE:
*. Only acceptable case-4, when lift and move the valves;
1) up to 10"- 300# body with VD (Diaphragm type)
actuators 2) up to 12"- 300# body with VC (Cylinder type)
actuators In the above two cases the lifting is limited to
max. height of 1.0 m and max. moving distance of 70 m.
CAUTION:
When handling the valve or the control valve
assembly, take its weight into account!

3.2.2 Installation valve
The valve has an arrow indicating the flow direction. Install
the valve in the pipeline so that the flow direction of the
valve corresponds to the flow direction marked on the pipe.
The mounting orientation of the valve should be vertical
position as it is shown on Fig.4.
Choose flange gaskets according to the operating
conditions.
Do not attempt to correct a pipeline misalignment by
means of flange bolting.
Loads on the valve body from pipeline vibrations can be
reduced by supporting the pipeline properly. Reduced
vibration also increases the lifetime of the positioner.
Where necessary, you can support the valve by the body,
using regular pipe clamps and supports. Do not fasten
supports to the valve or flange bolting or to the actuator,
see Fig. 4.
Fig. 4 Installing the control valve into pipeline using
supports
3.3 Hydrostatic testing and Line flushing
When the line is hydrostatic test and flushing, the control
valve should not used as an isolating valve. Make sure the
control valve always be opened position before start this
process. Otherwise valve and trim damage or failure of the
seals could result.
Flushing and hydrostatic test kit can be purchased from
Metso.
3.4 Control valve assembly
Check all joints, piping and cables.
Check that the actuator stop screws, positioner and limit
switches are calibrated. Refer to their installation,
maintenance and operating manuals.
3.5 Valve insulation
If necessary, the valve may be insulated. Insulation must not
continue above the upper level of the valve body, see Fig. 5.
Fig. 5 Insulation of the valve
4 MAINTENANCE
4.1 General
The Neles series GM-Omega multistage trim valves require
no regular maintenance. However, check the gland packing
for leakage. This section outlines the maintenance that can
be carried out by the user.
The numbers in parentheses refer to the parts lists and the
exploded views of the valve in Section 9.
4.2 Gland packing adjustment
In the event of a packing leakage tighten the hexagon nuts
(18) in ¼ turn steps each until the leakage is stopped. Do
not tighten more than necessary.
NOTE:
For any other mounting position, please consult the
factory.
CAUTION:
Flushing trim kit sholud be installed in the valve
(especially 'Omega trim' application) to protect the
original trim and the flow passages while the valve
installation and line flushing.
Unless this caution could result in clogging trim, low flow
rates, unstable control, valve leakage and exessive noise
and other trouble.
CAUTION:
Observe the safety precautions listed in Section 1.7
before starting work!
CAUTION:
When handling the valve or the control valve
assembly, take its weight into account!
NOTE:
If you send the valve to the manufacturer for repair, do not
dismantle it. Clean the valve carefully, including the inside.
For safety reasons, inform the manufacturer of the nature
of the medium when you send the valve.
NOTE:
Always use original spare parts to make sure the valve
functions as intended.
