Building on Rotork’s historical success with
innovative technology, the CVQ offers a highly
accurate and responsive method of automating
control valves without the complexity and cost
of a pneumatic supply. With an increased focus
on production costs and efficiency, accurate
control of the process variable is paramount.
With resolution figures better than 0.1% and the ability to
eliminate position overshoot, the Rotork CVA range helps to
maximize product quality and plant capacity.
CVA range actuators are self contained, purpose designed
and built for continuous remote electrical operation of
control valves.
This Manual covers the Quarter Turn Control
valve Actuator Range (CVQ).
CVQ 1200 & CVQ 2400
Refer to Rotork Publication P110E for full specification.
The actuator comprises:
•
DC brushless electric motor.
•
Reduction gearing with quadrant output gear.
•
Motor controller with speed, travel and torque limitation.
•
Electronic logic controls and monitoring facilities housed
in a double sealed watertight enclosure.
•
Hazardous area certification meeting international and
national requirements.
All torque and position settings as well as configuration of
the actuator are made using a non-intrusive Bluetooth device,
typically a PDA (not supplied).
