OBJECTIVE
This instruction manual contains important information
regarding ‘long-term’ storage requirements for
Jamesbury
bare-stem valves, valves with manual gears or levers, and
valves with pneumatic or electric actuators including
actuator accessories.
The following are recommendations for storage to
maintain product integrity during periods of storage up to
five (5) years when stored in an area as described in
Section 2
, and periodically inspected as described in
Section 4
.
2
LOCATION
We recommend the units are stored in a clean, dry, secure
warehouse. Units should not be stored on the floor. In
storage the units are to be protected from any harmful
effects listed below.
•
Sunlight
•
Ozone
•
Moisture (rain, flood, humidity, etc.)
•
Pests (mammal, insects, etc.)
•
Dirt, dust, sand, etc.
•
Mold and/or mildew
•
Temperatures below 32° Fahrenheit, or above 100°
Fahrenheit.
•
Flames
•
Radiation
•
Vibration
•
Chemicals
•
Mechanical damage caused by crushing or dropping
NOTE:
The major source of equipment deterioration
encountered in ‘long-term’ storage is from condensation
within the units. Should a reliable means be unavailable to
preclude this condensation within the unit, the purchaser
should consider the addition of heat source in electrical
enclosures during storage. Humidity indicator cards, or
equivalent, may also be used as an indicator of moisture
levels present in the storage area.

EQUIPMENT ORIENTATION
1.
Valves may be stored in the vertical or horizontal
position.
2.
Missing or damaged end covers should be replaced
immediately in order to prevent contamination.
3.
Valves or valve assemblies should be placed on a skid
and covered to prevent dust, sand, dirt, or moisture
from entering into the valve. Pneumatic and electrical
conduit openings should be plugged.
4.
For storage of valve assemblies containing electric
actuators the preferred storage position is with the
valve stem and motor shaft in the horizontal position.
It is acceptable to position the valve stem vertical, with
the motor shaft horizontal.
5.
Valves may be stored as shipped, provided the storage
location and equipment orientation instructions in this
manual are followed.
6.
If valve shipping condition must be altered for
receiving inspection reattach flange covers promptly
and repackage valve or assembly.

STORAGE INSPECTION AND
MAINTENANCE
1.
Create and maintain a storage record log.
2.
Check the valve and any accompanying devices for
damage that may have occurred during shipping.
3.
Any deficiencies noted should be immediately
corrected. All maintenance activity should be recorded
in the log.
4.
Visual inspections should be performed on a semi-
annual basis. As a minimum, the condition of the
packaging, humidity indicator cards (if used), and the
integrity of all plugs and covers shall be checked.
5.
Steps should be taken to protect any un-painted
exterior surfaces on the valve and actuators. Light rust
on the exterior of the valves is permissible. This will
have little or no effect on their performance. Heavy
internal rust however, may be harmful and must be
corrected.
6.
Maintenance shall consist of correcting deficiencies
noted during inspection. All maintenance activity shall
be recorded in the log.
WARNING:
IT IS THE PURCHASER’S RESPONSIBILITY TO TAKE THE NECESSARY
PRECAUTIONS FOR THE PROTECTION OF VALVES IN STORAGE.
WARNING:
ONCE REMOVED FROM STORAGE, ALL VALVES SHOULD BE FULLY
RETESTED PRIOR TO INSTALLING IN PIPELINE.
WARNING:
VALVES MUST BE STORED IN THE FULLY OPEN OR FULLY CLOSED
POSITION. LONG-TERM STORAGE IN THE PARTIALLY OPEN POSITION
MAY PERMANENTLY DAMAGE THE SEATS.
