It is recommended that this manual is read carefully and entirely, before starting any
maintenance, in order to optimize intervention timing, and to ensure that suggested spare
parts and gaskets are available in the event of valve assembly.
For installation and maintenance operations no specific equipment or tools are required, other
than those usually available in the plant.
Emerson is always at the Customer's disposal for any further technical information.
1. Verification upon receipt and storage before installation
When the materials arrive, it is recommended to:
• Check the integrity of the case.
• Open the case and verify that there is no damage due to transportation.
• Do not open the barrier bag (if present).
• Verify that the contents are those stated on the packing list.
• Store the valves (unless damaged) in their original packaging.
Please observe the following:
1. Store the valves in a closed, clean and dry storage room.
2. Do not place packages directly on the ground.
3. Check the packages every two months.
4. Substitute the silica gel every six months. This is not applicable in the case of barrier bag
packages.
2. Handling
During handling operations, valves must be lifted and handled as indicated in fig. 1 by using lifting
equipment (fasteners, hooks, etc.) that must be sized and selected on the basis of valve weight
(indicated in the drawings).
If there are any eyebolts in the valve body, these can be used to lift the valve.
Do not use any lifting points located on the actuator to lift the valve. These lifting points are to lift
the actuator only.
Lifting and handling must be done only by qualified personnel.
Warning
Do not use any lifting straps that are either damaged or of inadequate/unknown size.
Emerson reserves the right to change the contents without notice RAIIC-0052-EN-1310
