SECTION 1 - VALVE STORAGE
1.1 Preparation for shipment and preservation
The valve is properly packed in order to protect
the parts that could be subject to deterioration
during transportation and storage on site.
Whenever applicable the valve shall be stored
within the original packaging.
In case either the unpacking or the replacing
of the original packaging become necessary
(should for example an inspection be
prescribed upon the arrival on site), the original
protection conditions of the valve shall be
preserved.
Moreover the following precautions shall
be taken:
1. The valve must be packed with the disc
in the closed position. The flange sealing
surfaces (raised faces) or the buttweld
ends are protected with suitable protective
grease (where applicable according to the
valve material selection). The end faces of
the valve must be protected with plastic or
wooden discs fixed with straps.
2. In case of bare shaft valves the ends of
the shaft must be protected with dedicated
packaging.
3. An appropriate packaging shall be
considered in case of a valve with "fail open"
pneumatic or hydraulic actuator, where
the valve disc is in the open position and
protrudes beyond the face to face.
An actuated valve must be securely and
safely palleted or crated with special
attention to ensure that parts of actuator
(especially tubing and fittings or accessories)
do not extend beyond the skid/crate.
4. The type of packaging must be defined
in the customer's order and will be
appropriate to ensure safe transportation
to final destination and conservation before
installation.
The operators shall be specifically trained to
avoid contamination.
