Control valve handling
WARNING!
CRUSHING HAZARD
During installation or removal of a control valve, always place the unit on a stable platform or
surface that supports its assembled weight.
Failure to comply may allow the control valve to roll, resulting in death, serious injury or
equipment damage.

Control valve storage conditions
Description
For long term storage, it is recommended that the complete control
valve assembly be stored under cover in a controlled environmental at-
mosphere in the original packaging. The storage temperature limits
are: 20 ºC to 60 ºC (68 ºF to140 ºF) .
Inspect O-rings for wear or damage during disassembly of the cover
and right before assembling the unit. Replace damaged elastomer.
FKM has an unlimited shelf life.
Examine the internal surfaces and flange faces of the control valve at
least once every three months.
Repack the control valve as originally received.
Do not remove nameplates or labels. Doing so will void the control
valve warranty.
When stacking equipment, follow all the safety standards taking into
account the type of box used, the maximum height of the equipment,
the maximum number of boxes stacked, etc.
