Rotork CVA Range - CVL Linear Control Valve Actuator

Brand: Rotork PLC

The CVA Range of linear (CVL) and quarter-turn (CVQ) 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 valve actuation.

The Rotork CVL linear, 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 CVL helps to maximise product quality and plant capacity.

The CVL delivers a range of sizes suitable for almost all linear control valve applications requiring highly accurate positioning.

It offers end users high standards in performance, build quality and overall value.
