A Basic Introduction to Electric Valve Actuators The basic description of an electric actuator is an actuator that is controlled by electric power. The application of an electric actuator is significantly wider compared to hydraulic actuators and pneumatic actuators. Electric actuators are widely used in many different fields like oil industries, food industries, and even chemical industries to name a few. In order for you to know about electric actuators, here are some guides to help you. The first step is to know the general features and parts of an electric actuator. Most of these electric actuators actually look sleek. Most of the time, the shell of these electric actuators are made of an aluminum alloy. The aluminum alloy allows any electromagnetic interference to be reduced. The light weight of these aluminum shells is also another reason why it is commonly used for electric actuators. Electrical actuators are also very convenient for most people to use. The electrical actuators are so convenient that you can install it in any position. This type of actuator is also designed and built with rust resistance and corrosion resistance. There is also a very powerful function when it comes to this type of actuator. Numerous signals can come out of these electric actuators. The advantages of installing an electric actuator are numerous. Being driven by electric power is just one of the many reasons why an electric actuator is so useful. Another reason is that the speed of transmission messages are very fast and the distance of transmission can be very far. This type of actuator can satisfy the need of long distance. The sensitivity and accuracy of these electric actuators are a lot higher compared to hydraulic actuators and pneumatic actuators. The electric actuator can greatly coordinate with electric regulators because of its basic features. Electrical actuators are not all good sometimes. Problems and issues would usually come up due to the complex structure of these electric actuators. One example of an issue is when it is operating and suddenly gets short circuited. This type of actuator often has a weak resistance to any explosions within the device.

The classification of these electric actuators is another important body of knowledge. Electric actuators are considered to be the most common of actuators. People can usually find these electric actuators in the market or stores. Rotary electric actuators and linear electric actuators are different classification of electric actuators based on their type of motion they use. The rotary electric actuator can be grouped with the part-turn and multi-turn type as well. Regarding the linear electric actuator, this type of electric actuator can actually be divided into gear-rotation types and push-pull types.

When it comes down to it, these electric actuators are very useful and functional for many purposes. Another plus to having an electric actuator is being able to work with numerous kinds of valves like the butterfly valve, control valve, gate valve, and ball valve.
