4 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.
When lifting a valve system from the shipping container,
position lifting straps to avoid damage to mounted
accessories. Systems with valves up to six inches may be
lifted by actuator lifting ring. On larger systems, lift unit using
lifting straps or hooks through the yoke legs and outer end of
body.
WARNING: When lifting a valve/actuator assembly with
lifting straps, be aware the center of gravity may be above
the lifting point. Therefore, support must be given to prevent
the valve/actuator from rotating. Failure to do so can cause
serious injury to personnel or damage to nearby equipment.
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
If a valve control package has been stored for more than one
year, inspect one actuator by disassembling it per the
appropriate
Installation,
Operation,
and
Maintenance
Instructions (IOM) prior to valve installation. If O-rings are
out-of-round, deteriorated, or both, they must be replaced
and the actuator rebuilt. All actuators must then be
disassembled and inspected. If the actuators O-rings are
replaced, complete the following steps:
1
Replace the pressure-balance plug O-rings.
2
Inspect the solenoid and positioner soft goods and
replace as necessary.
3
Test the control function of the positioner. Do not
disassemble to pilot relay module in the positioner.
