Valve actuators

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, and customization of the torque profile is available to suit individual valve requirements.
