BALL VALVES
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
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.
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 the 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 valve 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 any other things, 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 handling.
7. Maintenance space must be provided.
8. Although Metaltite
®
ball valves are designed
as bi-directional, sealing function in a closed
valve position excels for positive pressure
direction (from Body Cap side to Body side
direction). Generally install the valve with
the Body Cap facing to high-pressure side
when the valve is closed.
