Intelligent linear actuator from CIRCOR ideal for long run time operation
CIRCOR International, Inc. 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 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 loss of external power. The ECU is a function of the actuator that are designed to perform a closing operation in an emergency e.g. when the temperature/- or pressure limiter is triggered. Another benefit is that you are able to adjust the closing time depending on the application. The actuator also automatically returns to normal operation after a fail - safe or ECU function occurs.
The new actuator makes it easy to replace old-school synchronous drive technology for industrial, chemical, power and process actuation requirements. Using the newest brushless DC (BLDC) motor system, REact EQ-L offers high force and delivers up to 60 percent energy savings compared to synchronous drives. Other cost-saving features include over-force protection to prevent damage to the valve and actuator; reduction in maintenance due to 100 percent running time; and external LEDs indicating actuating direction for easy monitoring. Also included is a smart controller with several adjustable and easily selectable preset speeds.
Approved for protection rating IP 66 and NEMA 4x, CE design and NRTL certification, REact EQ-L's single gear unit-motor combination offers three different open/close force outputs; easy setup for worldwide voltage inputs and actuator protocols; and different speeds for different applications with only one motor and one gearbox.
