The CVA electric actuator from Rotork is claimed will hold the setpoint, feature no deviation and will respond quickly to a change. Controlled by a 4–20 mA signal, the CVA is suitable for the direct-drive actuation of linear or quarter-turn control valves. The CVA demonstrates accurate control valve automation, combined with advanced, non-intrusive calibration, valve diagnostics and the simplicity, user-friendliness and economy of electric operation. Mechanical features include the ‘double-sealed’ enclosure, whereby internal electrical components are permanently protected from the effects of the operating environment.
