Pneumatic actuators occupies what advantage?

in our work, knowledge of pneumatic actuator may not much, because in normal life or work, we are hard to see or learn about related knowledge of pneumatic actuators. Small make up today is for everybody to introduce about the advantages of pneumatic actuators. Pneumatic actuators occupies what advantage? First of all, the pneumatic actuators can be continuous signal reception, that is to say, after add electricity or gas, conversion device, and to accept a continuous signal. Also, pneumatic operation has certain positive and negative effect, generally can be according to our request for manipulation. Second, the pneumatic actuators movement speed is quite big, in many cases, when the load increases, the speed of the pneumatic actuators will be slow, and its output pressure is and operation pressure without any relationship, this for pneumatic actuator is a good separation. Finally, we can know is that the reliability of the pneumatic actuator is extremely high, maintenance is simple, ability to adapt to the environment is very strong, peers in the pneumatic actuator has what advantage? Pneumatic valve at more of time, also have certain ability of explosion proof, this is a kind of very good protection for workers. This also to a certain extent, greatly increase the service life of pneumatic actuators.
