New Rotork Electric, non-intrusive CVA control-valve actuators incorporate advanced technological features for high-precision valve positioning, enhanced HMI capabilities, energy savings, and fail-to-position protection. They are available in linear and quarter-turn actions for a wide range of demanding control-valve applications in pharmaceutical manufacturing environments.
They feature Rotorks double-sealed enclosure, which protects internal components from the effects of the operating atmosphere. The new actuators eliminate the need for costly air supplies 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, enabling process quality and output to be optimized. In addition, they include, as a standard feature, wireless Bluetooth communication technology that can be used for quick and easy actuator set-up and adjustment.
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.
