General instructions
Every Rotork actuator has been fully tested before leaving the
factory to give years of trouble free operation, provided that
it is correctly commissioned, installed and sealed.
To keep actuators in a good condition until they are installed,
Rotork recommends the following measures during storage:
• Ensure that the dust plugs are properly fitted to any
open fluid and electrical connections in order to prevent
debris from entering into the system during transport
and/or storage.
• The actuators are supplied on wooden pallets. They must
remain on the pallets until they are installed, in order to
prevent damage to the valve coupling flange.
• It is recommended to store actuators in a dry place,
providing appropriate protection against direct effects
of weather.
• Check the actuator condition every 6 months and verify
the above protection measures remain in place.
6.2
Long-term storage
If long-term storage is necessary, further operations must
be carried out to maintain the actuator in good working
condition, namely:
• Replace the plastic plugs by metal plugs to guarantee
a complete weatherproof protection of the fluid and
electrical connections, especially if the storage is
outdoors.
• The actuator must be stroked every 12-months, using
filtered, dehydrated air.
- Connect the pneumatic supply and electric power
(if present) to the actuator, according to the proper
operating diagram and wiring diagram reported in the
documentation of the specific project.
- Cycle the actuator at 80 psi (5.5 bar).
- Utilising the actuators control components, cycle the
actuator at least five times (i.e. five open strokes, five
close strokes).
- For actuators fitted with a mechanical manual
override, cycle the actuator by means of the
handwheel at least four times (i.e. four open strokes,
four close strokes).
- Subsequently disconnect the pneumatic and electric
(if present) supply from the actuator, and carefully re-
plug any open fluid and electrical connections.
• Remove the covers from the electric components
(if present), and ensure the terminals are clean and free
from oxidation and humidity. Reassemble the covers.
• In case of storage for over 12 months, confirm proper
operation prior to installation.
