1 SAFETY PRECAUTIONS
Precautions for using KTM valves safely are
Please read through this manual completely
before operating the valves.
OM-2 Gratite Seat Ball Valves are usable for toxic

Please use the valves according to warnings and
cautions described in this document. Failure to
do so could result in an accident due to wrong
storage, installation, operation, maintenance and
disassembling and/or serious damage.
Please keep this manual in a handy place for
immediate reference; be sure to provide it to
purchaser, contractor, piping designer, user,
operator or maintenance technician.
highlighted with the following two warning
signs according to the level of danger posed.
Please read the postscript carefully to ensure
safety and prevent any damage before starting
to use the product.
WARNING
A potentially hazardous situation which, if not

2 SPECIFICATION
The safety of the valves and conformity with
your equipment should be checked by the
design engineer or those who determine the
specification based on the catalog or other
technical data.
Upon arrival, the applicable conditions
(temperature, pressure, fluid-characteristics,
environmental conditions, mounting gauge
etc.) should be first checked to make sure they
arecorrect.
For the standard specifications, refer to the table
below and the catalog.
GRATITE SEAT RATING
WARNING
Do not use valves beyond specifications or limits
indicated in the catalog.
CAUTION
1. These models may be used indoors or
outdoors. If however used in an environment
exposed to gas, an appropriate type and
material should be used to prevent corrosion
or rusting. (Details on the component
materials are provided in the catalogs.)
2. To prevent accidents, custom-made valves
for special treatment and operation should be
ordered for specific applications using oxygen
and hydrogen peroxide.
3 RANGE OF APPLICATION
Pressure/Temperature Rating
OM-2 Gratite seat ball valves have a range
of application defined by temperature and
pressure. Please operate the valve within the
range shown below. Operating the valve outside
that range may result in failure of valve body or
parts and leakage of the fluid. (The pressure/
temperature rating is defined by body material
and seat material.)
CAUTION
The maximum temperature for applications to
oxidative fluids and in oxidative environment is
449˚C.
The maximum temperature for models with
nominal diameters 6” (150 mm) and 8” (200 mm)
is normally 350˚C.
4 STORAGE AND PRESERVATION BEFORE
INSTALLATION
The storage of the valves should be in
accordance with the following criteria:
1. Storage warehouse should be clean and dry.
2. The ball must be in open position and
the end flanges must be protected with
appropriate seal discs.
3. Do not remove the bore protection
cover until installation to avoid rust and
contamination with foreign substances.
4. Periodical checks have to be carried out
in the storage area to verify that the above
mentioned conditions are maintained.

INSTALLATION AND OPERATION MANUAL
CAUTION
1. The ball valves are delivered with the ball in
full-open position and should be stored as they
are. Keeping the ball in other positions, incl.
half-open position, for an extended period of
time could cause seat leakage.
2. Do not place consignment package directly on
the ground.
3. Do not expose consignment packages to the
rain/wind or directly to the sun.
4. Storage in an open area for a limited period
can be considered only if the valves have
appropriate packing (packed in cases covered
with vinyl sheets protecting from rain, wind,
dust etc).
5. Store in a dry and well ventilated condition.
6. If storage is anticipated for an extended period,
the desiccant bags (if supplied) should be
changed every six months.
5 TRANSPORTATION
WARNING
1. When handling valves, the correct equipment
and accessories (slings, fasteners, hooks
etc.) must be sized and selected, taking into
consideration the individual and/or overall
valves weight indicated in the packing list
and/or delivery note.
2. Lifting and handling must be done only by
qualified personnel. Improper hoisting can
cause valve deformation or damage from
dropping the valve.
3. Do not lift the valves by using lifting points or
lugs located on the actuator, as these lifting
points/lugs are for the actuator only.
4. Do not lift the valve by its hand-lever as these
levers are not designed to take the load of
the whole valve. Doing so may cause the
lever to brake off or be disconnected from the
valve, resulting in possible valve damage or a
person’s injury.
5. Avoid lifting over people’s heads, equipments
or anything else that can possibly be damaged
or cause of injury in the event that the lifted
load falls off the handling equipment.
6. All local safety regulations must be observed
and complied with at all times.
6 INSTALLATION
The following instructions will make for a
satisfactory and long life service of the valve.
1. Remove the valve from the shipping package
(box or pallet) carefully to avoid any damage
to the valve and actuator (plus accessories
where applicable).
2. Confirm that the materials of construction
listed on the valve nameplates are
appropriate for the intended service and are
according to specifications. When in doubt,
contact KTM or your local Emerson facility.
3. Define the preferred mounting orientation
with respect to the system pressure. Where
applicable, the arrow on the body helps to
identify the upstream side (high pressure)
and downstream side (low pressure).
4. Fasteners like bolts and nuts at each
connecting portion on the valve should
be checked and retightened in case
they were loosened due to shock during
transportation. When tightening nuts, use a
closed wrench for safety.
5. Before installation, the protection cover on
the bore must be removed.
6. Manually operated valves, may be installed
on pipes at any angle, horizontally, vertically
or any other direction. It is however
recommended to consider facilitating
maintenance and operation of the valve.
7. Maintenance space must be provided.
CAUTION
1. Ensure that there are no solid objects such as
pieces of wood, plastic or packing materials
within the valve or on the valve seat. It is
recommended to flush pipes before installing
the valve. If this is not possible, the installed
valve must be in its open position before
flushing takes place.
2. Unless otherwise recommended by KTM, the
valves should be installed with the ball in open
position to ensure that the seat rings are not
damaged during installation.
3. Use appropriate gaskets which comply with
standards or specifications.
4. Tighten the flange bolts with a closed wrench,
using a ‘crisscross’ pattern that alternately
tightens the bolts located 180 degrees apart
(see Fig. 1). Unequal partial tightening places
stress on lined pipes which may damage the
flange or produce excessive operation torque.
5. Failure to fabricate pipes without excessive
stress will result in leakage, poor operation
or failure of the valves.
6. When conducting a pressure test of the pipe
system, the valves should be in a partially open
position. Testing at closed position will impose
too much load and will cause leakage from
seats. Check for any leakage from the joint
flange and gland portion during the pressure
test. After conducting pressure test, return to
fully open/closed position at once.
7. If the piping system is pressurized with water
for testing, and if the piping system has been
shut down for a long time after testing, the
following measures should be taken:
• Use corrosion inhibitor with water to
pressurize the piping system.
• After testing, the piping system should be
depressurized and the test water completely
drained.
• Ensure that the corrosion inhibitor does not
leave a residue within the system as the
particulates may damage the valve sealing
surfaces.
