Electric Actuator Designs
Electric Actuator Designs
Electric actuator are designed according to the specific functions that they serve within the engines in which they are installed--usually to open or close valves of different sizes. Some actuator are designed to withstand full thrust and must travel a relatively long distance to cover the diameter size of a large valve. Other valve discs, such as the globe valve, may require a shorter movement by an actuator. An example of a full-thrust actuator is the Thrust Vector Control of the Space Shuttle Rocket Booster. Short-travel actuators are the most common types of actuators in use. For instance, your house thermostat uses short-travel actuators for temperature controls and reversals.

Functions of Electric Actuators
Due to increasing decentralization within automation technology, the functions of electric actuator have increased in many ways. This revolution was also impacted by the invention of state-of-the-art microprocessors, which has in turn influenced the position control. New electric actuator are now equipped with new process controllers with self-adaptation potential, making it easier to attain new automation standards.
