New Rotork CQ pneumatic and hydraulic valve actuators are engineered to deliver a self-contained solution for applications demanding functional integrity and safety where space is limited.
They incorporate a fully concentric, balanced compact design that provides reduced dimensions when compared with conventional scotch-yoke actuators. The CQ’s symmetric design is totally enclosed with a rugged, waterproof housing which contains a helical mechanism that transforms linear piston motion into 90º (+/-5º) rotation for the operation of quarter-turn valves.
Output torques up to 600,000 Nm (5.3 million lbf-in) are available. Customization of the torque profile is available to suit individual valve requirements. Environmental and hazardous area certifications include IP66M/IP68M, PED, ATEX, IECEx and GOST. The actuators are also suitable for SIL3 safety related duty.
