What are the special features of pneumatic actuators?

pneumatic actuators and other types of actuators, there are many common features, have their own special function exist at the same time, in many industries play a very important role, can say in these industries, the achievement of pneumatic actuators is played. Compared with other types of actuators, pneumatic actuators have special features, and because these features advantages can we choose it. So, pneumatic actuators have what special features? The function of the pneumatic actuators, pneumatic apparatus has positive and negative effect, signal increases stem downward movement is called the function, whereas for reaction; Pneumatic actuator movement speed is larger, but when the load increases speed slower, has very good adjustment function. Pneumatic actuators have many features compared with same kind of actuator, there are a lot of performance features are similar actuators. Many purchaser in addition to the procurement pneumatic ball valves, by the way of purchasing pneumatic actuators. Pneumatic actuator output force is associated with the stress of operation, reliability is very high, very stable, but after air break valve cannot keep, to want to keep must a valve is required. Pneumatic actuators, of course, also some deficiencies, such as pneumatic actuators inconvenience to implement piecewise control and program control, through perfecting and achievable. Now maintain/pneumatic actuator is very simple, simple do daily maintenance and adaptability to environment is also very good.
