STORAGE REQUIREMENTS
The valves have been shipped in the partially open position. Upon receipt of the valves at
destination, the crates should be examined thoroughly for signs of mishandling or damage
during shipment. With the valves strapped to the shipping skids, all bolting should be
checked to ensure that the joints are secure. Bolting on occasion, may become loosened
during shipment and handling.
The valves should then be stored in a sheltered area to protect them from the elements,
dirt and foreign material. They should not be exposed to the atmosphere, uncrated or
removed from the shipping skids except in a clean area just prior to installation.
If the valves are not to be installed within a short period of time after receipt, and will
require long-term storage, the following should be adhered to:
(a)
They should be stored in an upright position and where there is minimal
temperature variations and the temperature does not drop below 50
°
F.
(b)

accumulation of dust or foreign matter.

A check-off tag should be affixed to each unit and should be dated and signed off
by the inspector witnessing the inspection which is recommended at 6-month
intervals.
