9.1.5 Storage
Protect stored valves against ingress of dirt and airborne contaminates
and avoid frost or direct sunlight. Do not allow the temperature of the
storage area to rise above the maximum continuous temperature rating of
the selected element (refer to Section 9.1.3).
Storage is permitted down to -40°C (-40°F) for valves containing Nitrile,
EPDM, Neoprene ‘O’ rings and down to -26°C (-14.8°F) for valves
containing FKM (Viton) ‘O’ rings but this must be followed by a slow
increase of no higher than 1°C per minute.
Valves must be kept dry and not subjected to any shock loads or abrasion.
Valves may be stored in any position and will not deteriorate with time,
with the exception of the ‘O’ rings, which must be replaced after 7 years.
