ATEX Actuators
ATEX Actuators are approved for use in potentially explosive environments. They are based upon a unique design that integrates a highly efficient planetary roller screw mechanism with a high torque servomotor in a single self-contained package. The roller screw outperforms rival ball screws by a factor of 15, in terms of travel life and load carrying capacity. It consists of multiple threaded rollers assembled in a planetary arrangement around a threaded shaft. This highly robust design is designed to provide reliable and precise operation over thousands of hours.
The combination of the planetary roller screw and servomotor produces an all-electric actuator which is extremely compact, yet delivers similar performance to hydraulic actuators in terms of force (907 Kilograms max) and torque capability, while surpassing them in speed (up to 635mm/s), efficiency, positioning performance, operating life and environmental impact.
ATEX Actuators offers a unique combination of high speed, performance and accuracy in a compact package, plus the flexibility of compatibility with almost any resolver- based servo amplifier. The optimised performance features of the actuators are evident in valve and damper control applications, where the actuators continuously hold the position of the valve stem, or shaft, allowing extremely fast response to the smallest command signal changes, without overshoot, even when friction is present. This results in improved loop performance and reduced process variability.
Also optimising the ATEX actuators for process applications is their excellent contamination protection. In conventional rotary to linear devices the critical mechanisms are exposed to the environment and therefore require frequent inspection, cleaning and lubrication. The explosion-proof rating, high performance and environmental packaging of the ATEX actuators mean that they are ideally suited to the widest range of applications.
