Compact actuators
04 March 2015
With its CQ Compact, Rotork has introduced a range of fully concentric, balanced design pneumatic and hydraulic valve actuators that deliver a reliable and efficient self-contained solution for applications demanding functional integrity and safety where space is limited.
In addition to providing reduced dimensions when compared with conventional scotch-yoke actuators, the CQ’s symmetric design also presents a perfect weight balance on the valve, enabling increased efficiency for assembly and disassembly.
The totally enclosed, rugged CQ weatherproof housing contains a helical mechanism which transforms linear piston motion into 90º (+/-5º) rotation for the operation of quarter-turn valves. As an option, rotation can be increased to 180º. Complete customisation of the torque profile is available to suit individual valve requirements.
