storage
When valves are to be stored for some time
before being fitted, storage should be in
the original delivery crates with any waterproof
lining and/or desiccant remaining in place.
Storage should be off the ground in a clean, dry,
indoor area. if storage is for a period exceeding
six months the desiccant bags (if supplied)
should be changed at this interval.
protection
Valves are delivered with protection according to
customer's specification, or in accordance with
the Quality assurance Manual, to protect the
valve seats and closure member from damage.
Wrapping and/or covers should be left in place
until immediately before fitting to the pipe.
selection
Ensure the valve's materials of construction
and pressure/temperature limits shown on
the identification plate are suitable for the
process fluid and conditions. if in doubt contact
the manufacturer.
