VALVE STORAGE
Preparation and preservation for sShipment
All valves are properly packed in order to protect
the parts that are subject to deterioration during
transportation and storage on site. In particular,
the following precautions should be taken:
1. The valves must be packed with the disc in
the closed position.
1a. Flanged sealing valves: The flange
sealing surfaces (raised faces) of the
valves shall be protected with suitable
protective grease. The end faces of the
valve must be protected with plastic or
wooden discs fixed with straps.
1b. Buttweld end valves: The weld ends
surface shall be protected with suitable
protective like Deoxaluminite. The end
shall be closed with plywood or plastic
disc fixed at the edge by straps.
2. The type of packing must be defined in the
Customer’s Order and shall be appropriate
to ensure safe transportation to final
destination and eventual conservation
before installation.
Handling requirements
A - Packed valves
Crates: Lifting and handling of the packed
valves in crates will be carried out by a fork lift
truck, by means of the appropriate fork hitches.
Cases: The lifting of packed valves in cases
should be carried out in the lifting points
and at the center of gravity position which
have been marked. The transportation of all
packed material must be carried out safely and
following the local safety regulations.
B - Unpacked valves
1. The lifting and the handling of these valves
has to be carried out by using appropriate
means and at respecting the carrying limits.
The handling must be carried out on pallets,
protecting the machined surfaces to avoid
any damage.
2. With valves of large dimensions, the sling
and the hooking of the load must be carried
out using the appropriate tools (brackets,
hook, fasteners, ropes) and load balancing
tools in order to prevent them from falling
or moving during the lifting and handling.

Storage and preservation before installation
In case the valves have to be stored before
installation, the storage has to be carried out
in a controlled way, and has to be performed in
accordance with the following criteria:
1. The valves have to be stocked in a closed,
clean and dry storage room.
2. The disc must be in the closed position,
and the end faces must be protected with
plastic or wooden discs fixed with straps.
If possible, keep the original protection.
3. Periodical checks have to be carried out
in the storage area to verify that the above
mentioned conditions are maintained.
WARNING
For valve handling and/or lifting, the lifting
equipment (fasteners, hooks, etc.) must be sized
and selected while taking into account the valve
weight indicated in the packing list and/or delivery
note. Lifting and handling must be made only by
qualified personnel.
Caution must be taken during the handling to
avoid that this equipment passes over the workers
or over any other place where a possible fall
could cause damage. In any case, the local safety
regulations must be respected.
NOTE
Storage in an open area for a limited period can be
considered only in case the valves have appropriate
packing (packed in cases lined with tarred paper, and
contents well protected with barrier sacks).
Do not place consignment packages directly on the
ground.
Do not expose consignment packages to the weather
or directly to the sun.
Check the packaging every two months.
INSTALLATION
Preparation before installation
1. Carefully remove the valve from the
shipping package (box or pallet) avoiding any
damage to the valve.
2. The valves are shipped with the ends
protected with caps and a thin layer of
protective grease. Before installing the
valve, remove the caps and clean carefully,
then degrease both surfaces with a solvent.
Clean the inside of the valve by using an air
line. Ensure that there are no solid objects
such as pieces of wood, plastic or packing
materials within the valve or on the valve
seat.
3. Confirm that the materials of construction
listed on the valve nameplates (service and
temperature) are appropriate for the service
intended and are as specified.
4. Define the preferred mounting orientation
with respect to the system pressure.
The arrow on the body identifies the
upstream side (high pressure) and
downstream side (low pressure).
WARNING
Verify that the direction of the flow in the line
corresponds to the arrow indicated on the valve
body.
