　　Electric actuators and pneumatic devices each have their own characteristics. Let's start by describing pneumatic devices.

　　Pneumatic devices have three obvious advantages:

　　1. The load of pneumatic devices is relatively large, which can adapt well to some high torque outputs. Although this is the case, electric actuators can now withstand relatively large loads and catch up with the level of pneumatic loads. Therefore, this point is only for your reference, after all, the situation is different.

　　2. Compared to other devices, pneumatic devices have lower requirements for the working environment. They can be used in some flammable and explosive situations, and even in many harsh environments such as dusty, strong magnetic, high radiation, or strong vibration.

　　3. The pneumatic device operates quickly and responds very quickly.

　　The advantages of electric actuators are mainly reflected in the following points:

　　1. Compared to other devices, electric actuators have a smaller volume because they have a simple structure, simple components, and a very compact structure, making them easy to assemble.

　　2. In terms of the requirements for the driving source, the advantage of electric actuators over pneumatic devices is very obvious. Because electric actuators have simple requirements for the driving source, the power supply in our vehicles can generally serve as the driving source for electric actuators. However, pneumatic devices require air and compression driving devices to provide the driving source, which is very inconvenient.

　　3. Electric actuators do not require external power to maintain the load, while pneumatic devices require continuous pressure supply to maintain the load. It is precisely because of this that electric actuators do not have additional pressure devices, making them appear relatively quiet during operation. However, pneumatic devices require external pressure supply, resulting in noticeable noise. In the case of executing large loads, in order to reduce noise, We also need to add an additional muffler.
