Although most actuators are used for opening and closing valves, the design of today's actuators goes far beyond simple switching functions. They include position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules, and PID control modules, all of which are installed in a compact housing.

As more and more factories adopt automation control, manual operations are replaced by mechanical or automated equipment. People demand that the actuator can play an interface role between the control system and the mechanical movement of the valve, and also require the actuator to enhance work safety performance and environmental protection performance. In some hazardous situations, automated actuator devices can reduce personnel injuries.

Some special valves require emergency opening or closing in special circumstances, and the valve actuator can prevent further spread of danger while minimizing factory losses. For some high-pressure large-diameter valves, the required output torque of the actuator is very large. In this case, the required actuator must improve mechanical efficiency and use a high output motor in order to operate the large-diameter valve smoothly. For some small torque valves, precision electric valves are also used, which have the advantages of light weight, compact structure, and functionality compared to ordinary types.

The main advantages of electric actuators are high stability and user applicable constant thrust. The maximum thrust generated by the largest actuator can reach up to 225000kgf, and only hydraulic actuators can achieve such a large thrust. However, the cost of hydraulic actuators is much higher than that of electric actuators.

The anti deviation ability of electric actuators is very good, and the output thrust or torque is basically constant, which can effectively overcome the unbalanced force of the medium and achieve accurate control of process parameters. Therefore, the control accuracy is higher than that of pneumatic actuators. If equipped with a servo amplifier, it is easy to achieve the exchange of positive and negative effects, and it is also easy to set the cut-off signal valve position state (hold/fully open/fully closed). In case of a fault, it must stay in its original position, which pneumatic actuators cannot do. Pneumatic actuators must rely on a combination protection system to achieve position protection.
