CIRCOR International, Inc., a manufacturer, and marketer of differentiated technology products and sub-systems announces the RTK® REact EQ-L electric intelligent linear actuator for high-range force output. RTK REact EQ-L actuators are ideal for processes that depend on 100 percent running time, including industrial, chemical, and power applications. Corrosion-resistant variants have been specially designed for offshore applications. The REact EQ-L electric actuator offers an all-in-one intelligent package for applications with opening/closing forces from 15/3380 pound-force (lbf) to 30-kilo Newtons/6750 lbf.
The new REact EQ-L opens the door for Industry 4.0 functionality and flexibility for multiple signal exchange systems in open digital protocols for process automation. Outfitted with RTK’s optimized REpos digital positioner, the actuator offers data logging functions and remote control through Profibus or CANopen. Using field device notification of diagnostic status, users can expect to conduct a timely, status-based intervention to promote higher system availability and reduced maintenance costs.
The new RTK REact EQ-L is also equipped with a mechanical Fail-Safe and Emergency Closing Unit (ECU) function. The Fail-Safe can close the valve on the loss of external power. The ECU is a function of the actuator that is designed to perform a closing operation in an emergency e.g. when the temperature/- or pressure limiter is triggered. Another benefit is that you can adjust the closing time depending on the application. The actuator also automatically returns to normal operation after a fail-safe or ECU function occurs.
