September 25, 2008

The new line of Rotork electric, non-intrusive CVA control-valve actuators provides a major technological advance in precise operation for a wide range of control-valve applications in water and wastewater treatment plants.

Other features include advanced HMI capabilities, state-of-the-art fail-to-position protection, and the elimination of costly air supplies. They are available in linear and quarter-turn actions and are easily integrated into most process control environments, including those that use Hart and Foundation Fieldbus protocols.

CVA actuators provide extremely precise control-valve operation with repeatability and resolution performance at <0.1% of full scale. They include, as a standard feature, wireless Bluetooth communication technology that can be used for quick and easy actuator set-up and adjustment.

Also, all Rotork CVA actuators incorporate a data logger, which provides an extensive record of such operational and maintenance-related data as valve torque profiles, dwell times, and relevant statistical information.

They utilize a built-in super-capacitor that provides an advanced, programmable method for fail-to-position protection.

Rotork CVA actuators can be specified for single-phase AC or DC electrical supplies.
