Rotork CQ pneumatic and hydraulic valve actuators 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. Their symmetric design is totally enclosed with a rugged, waterproof housing which contains a helical mechanism that transforms linear piston motion into 90-degree rotation for the operation of quarter-turn valves. 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. They are suitable for SIL3 safety-related duty. 336/659-3493; www.rotork.com.
