10.0 STORAGE REQUIREMENTS
The valves have been shipped in the closed 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 yoke cap
and gland bolting should be checked to ensure that the joints are secure. On occasion, bolting could become loosened during
shipment and handling.
The valves should 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) The valves should be stored in an upright position, stem vertical, and where there is minimal temperature variation
and the temperature does not drop below 50°F.
(b) In their storage condition, the valves should be wrapped in polyethylene to prevent accumulation of dust or
foreign matter.
(c) 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 six-month intervals.
(d) The shelf life for grafoil and graphite filament packing and spiral-wound gaskets is indefinite when stored under the
proper conditions.
