STORAGE AND UNPACKING
4.1 Storage
FLOWSERVE Control valve packages (a control valve and
its instrumentation) are typically well protected from
corrosion. Nevertheless FLOWSERVE products must be
stored in a clean, dry environment such as an enclosed
building that affords environmental protection. Heating is not
required. Control valve packages must be stored on suitable
skids, not directly on the floor. The storage location must also
be free from flooding, dust, dirt, etc. Plastic caps are fitted to
protect the flange faces and positioner ports to prevent the
ingress of foreign materials. These caps should not be
removed until the valve or positioner is actually mounted into
the system.
If FLOWSERVE products (especially sealing materials) have
been in storage for longer periods check these for corrosion
or deterioration before using these products. Fire protection
for FLOWSERVE products must be provided by the end
user.
4.2 Unpacking
While unpacking the valve and/or Logix 500MD+ positioner,
check the packing list against the materials received. Lists
describing the system and accessories are included in each
shipping container.
In the event of shipping damage, contact the shipper
immediately. Should any problems arise, contact a Flowserve
Flow Control Division representative.
4.3 Pre-installation Inspection
When installing a positioner, verify the shaft has not been
damaged and that the plugs and cover are in place. The
plugs keep debris and moisture from damaging the internal
components of the positioner. If the positioner has been
contaminated, clean the positioner components gently with a
soft damp cloth. Some components may be removed for
better access. See section 13 MAINTENANCE AND
REPAIR. Check connectors to ensure that no debris is
present. Port screens can be removed with a flat screwdriver
for access to internal passages.
