This smart linear actuator has a high range of force output
The RTK REact EQ-L electric intelligent linear actuator (photo) is ideal for processes that depend on 100% 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 package for applications with opening/closing forces from 15 to 30 kN (3,380 to 6,750 lbf). The 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 the optimized REpos digital positioner, the actuator offers data logging functions and remote control through Profibus or CANopen. The 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 is designed to perform a closing operation in an emergency, such as when the temperature or pressure limiter is triggered. The actuator automatically returns to normal operation after a fail-safe or ECU function occurs. — Circor International, Inc., Burlington, Mass.
