The pneumatic actuator has was mad that the source easy to operate, the pollution of the environment, the movement nimble rapid, the job safety is unreliable, the operation service simple as well as is suitable for under the adverse circumstance characteristics and so on work, thus in ramming processing, injection molding and compression casting and so on virulent or under high temperature environment work, on the engine bed, the yummy treats, the measuring appliance and in the light industry profession small works and so on components' transportation and automatic assembly, the electronic products transportation, automatic peg grafting, processes and so on ammunition in production automation are widely applied. Therefore the pneumatic actuator is one kind easy to promote popularly realizes the industrial automation applied technology. Pneumatic system's application, caused various countries industrial field universal recognition, the air operated profession has become one of industrial nation development speed quickest professions.
