From the overall production process standpoint, fail safe actuators represent a major challenge. Greatest responsibility, reliability, and flexibility come together in the making of these actuators. The technology is based on an electric actuator with a purely mechanical safety function. In the event of a power outage or triggering of the safety function, the actuator moves into a preset position so that no hazards are posed to humans or the environment.
