Compact Valve Actuators

Rotork’s new 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 smaller dimensions when compared with conventional scotch-yoke actuators. The CQ’s symmetric design is enclosed in a rugged, waterproof housing, which contains a helical mechanism that transforms linear position motion into 90° (+/-5°) rotation for the operation of quarter-turn valves. Output torques of up to 600,000 Nm (5.3 million lbf-in.) and customization of the torque profile are available. Environmental and hazardous area certifications include IP66M/IP69M, PED, ATEX, IECEx, and GOST.
