Mechanical considerations
• K-TORK range actuators can be mounted on valves in
almost any desired position.
Important: To function properly, certain accessory
and control components e.g. filter drains, pneumatic
reservoirs; require proper orientation with respect to
gravity. Contact Rotork if in doubt.
• Ensure that all fasteners are adequately tightened to avoid
loosening during normal operation, take into account the
vibrations induced by the dynamics of the pipeline.
• All tubing used to provide pneumatic power to the
actuator must be free from contaminants and debris.
Ensure tubes are adequately fastened and supported to
minimise repetitive stress induced the dynamics of the
pipeline.
• Ensure there are no leaks from any pneumatic
connections. Tighten as required.

ACTUATOR REMOVAL FROM THE VALVE
The end-user is in charge of removing the actuator from the
valve.
The actuator is to be removed exclusively by
competent and qualified staff, wearing/using appropriate
personal protection devices.
Ensure sufficient free space is available for the disassembly of
the actuator from the valve.
Do not remove the actuator from the valve in the
event the valve is blocked in the intermediate position
(the valve stem must be in such a position so as not to
rotate during the disassembly of the actuator). Contact
Rotork.
In order to disassemble the actuator from the valve, proceed
as follows:
• Cut off the pneumatic and electrical power supply
(if present).
• Remove the pneumatic supply pipe from the actuator
and vent any storage tanks (If present).
• Remove control and signal lines from electric components
(if present).
• Sling the actuator following the instructions in section 5.
• Unscrew the bolts or the nuts from the stud bolts fixing
the actuator to the valve.
• Lift and remove the actuator from the valve.
