Electric Actuators
Rotork is the home of the flagship IQ intelligent electric actuator range. The IQ range features legendary innovations including Rotork’s unique double-sealed enclosure, ‘non-intrusive’ infrared commissioning, datalogging and predictive maintenance capabilities. More recent innovations include the advanced display, Bluetooth® communications interface and absolute encoder.
The 3rd Generation IQ Intelligent Actuator
For 60 years Rotork has used innovation for designing reliable, flexible and robust valve actuators and control systems. Continuing our ethos of evolving design, the next generation IQ multi-turn and IQT part-turn actuators are now available. Reliability standards have been set even higher, it is simpler to commission and use and is unrivalled in its ability to provide valve and process control operational data.
With the revolutionary dual stacked display, information about your plant and process is available at your fingertips, allowing unparalleled data analysis of the condition and operational status of the valve; data analysis that enables accurate asset management of your plant. Rotork innovation at its best.
