Electric Control Valve Actuators deliver precision operation.
October 4, 2011 -
All-electric, non-intrusive CVA control-valve actuators, available in linear and quarter-turn actions, deliver repeatability and resolution of less than 0.1% FS. Design promotes integration into process control environments, including those using Hart and Foundation Fieldbus protocols, and wireless Bluetooth communication technology aids setup/adjustment. Specifiable for single-phase AC or DC supplies, products also incorporate data logger and fail-to-position protection.

Rotork Electric Control-Valve Actuators Provide Precise Operation
New Rotork electric, non-intrusive CVA control-valve actuators provide a major technological advance in precise operation, HMI capabilities, and fail-to-position protection as well as significant energy savings.
They are available in linear and quarter-turn actions and are suitable for a wide range of control-valve applications throughout the plant. The new, all-electric 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. 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.
