CONTROL-VALVE ACTUATORS

Electric, non-intrusive CVA control-valve actuators provide HMI capabilities, fail-to-position protection and energy savings. They are available in linear and quarter-turn actions and there is no need for air supplies. Repeatability and resolution are less than 0.1% FS. Designed for process control applications, including those that use HART and Foundation Fieldbus, the actuators include wireless Bluetooth communication that can be used for actuator set-up and adjustment. A data logger provides data such as valve torque profiles and statistical information.
