9.0 TRANSPORT / STORAGE
Severe shock and vibration should be avoided during transport. Store it in a clean and dry environment.
Valves are ready for operation upon delivery. The protective port plugs should not be removed until
immediately before connecting the piping. To avoid damaging valve or/and position indicator, do
not lift or carry by the handle, or position indicator.
It is recommended to transport valve with the lifting equipment suitable for the weight to be moved. Do
not hook-up lifting equipment to accessory such as handle, or pressure bores. When using a
suspension belt it must be placed around the valve body, position indicator, providing edge protection
and ensuring weight distribution. Transport/storage temperature is recommended to be between
-40° C (-40° F) to +93°C (200°F). Protect existing sealing surface on the connections from damage. Do
not damage the corrosion protective layer.
