8.0 Storage
Rotork actuators are fully tested before leaving the factory.
To keep actuator in good condition until installation, at least
the following measures are recommended:
• Check presence and assembling of dust plugs
• Keep the actuator on shipping pallet until installation
Never put the actuator directly on the ground.
• Actuator must be positioned with the centre body
cover upwards
• Protect the valve coupling area (adapter flange
and coupling joint, etc.) with rust preventive oil
e.g. Mobilarma LT or equivalent
• Protect against weather action, covering the actuators
with appropriate polyethylene sheets
• Check the actuator condition every six months and verify
the above protection measures remain in place
Remove package only at the installation time.
If long term storage is necessary, further operations must
be carried out to maintain the actuator in a good working
condition:
• Replace the plastic plugs with metal plugs
• Stroke the actuator every 12 months
• Cycle the actuator (using filtered, dehydrated air) to the
working pressure indicated on the name plate
• Cycle the actuator with all the existing controls
(i.e. two complete strokes – one open, one closed)
at least five times
• Cycle the actuator fitted with the mechanical manual
override or hydraulic manual override by means of the
override for four complete strokes
• Disconnect the pneumatic and electric (if present)
supply from the actuator, and carefully close all the
threaded connections of the actuator
• Remove electrical components covers (if present) to
ensure control terminals are clean and free from oxidation
and humidity. Reassemble the covers
• In case of storage for over 12 months prior to installation,
it is recommended to operate the actuator to verify
correct operation
