The Rotork CVQ quarter-turn, electric process control actuator, offers a highly accurate and responsive method of automating control valves, without the complexity and cost of a pneumatic supply. With an increased focus on production costs and efficiency, accurate control of product through the pipeline is paramount. With resolution figures better than 0.1% and the ability to eliminate position overshoot, the Rotork CVQ helps to maximise product quality and plant capacity.The CVQ delivers a range of sizes suitable for almost all quarter-turn control valve applications requiring highly accurate positioning. It offers end users high standards in performance, build quality and overall value.Features1-phase or DC power supply optionsQuarter-turn drive actionOn-board datalogger included as standardBluetooth compatible for local setup / control and diagnosticsAccurate and repeatable positional control using 4-20 mA signalDigital communication options including HART®, Profibus® and Foundation Fieldbus®Direct torque / thrust measurement for protection and monitoringScalable control input characterisationConfigurable fail-to-position option using supercapacitor technologyOptional Intrinsically Safe control inputs and feedback outputsContinuous unrestricted modulation duty - S9Watertight IP68 and explosionproof enclosuresOptional manual override.See CVA Range Literature Page for Further Details
