Rotork CVA Range - CVQ Quarter-Turn Control Valve Actuator

Brand: Rotork PLC
The CVA range of linear and quarter-turn actuators provide an electrically powered process control operator suitable for most control valve types and sizes. 

The CVA sets a new standard for process control and valve actuation.

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 maximize 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.
Features
  • 1-phase or DC power supply options
  • Quarter-turn drive action
  • On-board data logger included as standard
  • Bluetooth compatible for local setup / control and diagnostics
  • Accurate and repeatable positional control using 4-20 mA signal
  • Digital communication options including HART®, Profibus® and Foundation Fieldbus®
  • Direct torque / thrust measurement for protection and monitoring
  • Scalable control input characterization
  • Configurable fail-to-position option using supercapacitor technology
  • Optional Intrinsically Safe control inputs and feedback outputs
  • Continuous unrestricted modulation duty – S9
  • Watertight IP68 and explosionproof enclosures
  • Optional manual override
