INSTALLATION AND MAINTENANCE INSTRUCTIONS

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 plug 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.
• 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.
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).
CAUTION
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.
Do not use the lifting points located on the
actuator, if any, to lift the valve. These lifting
points are for the actuator only.
Y-type globe valves
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.

INSTALLATION

Preparation before Installation
1. Carefully remove the valve from the
shipping package (box or pallet) avoiding any
damage to the valve or, in case of automated
valves, to the electric or pneumatic/
hydraulic actuator or instrumentation.
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 de-grease both surfaces with a solvent.
Clean the inside of the valve with a clean
cloth.
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. If
any (see arrow on the body), identify the
upstream side and downstream side.
WARNING
See the actuator user manual for the actuator
preparation.
