The most commonly applied actuator is the pneumatically driven actuator, because the power source – compressed air – is relatively cheap as compared to a human resource or electric or hydraulic power sources. From a maintenance point of view, pneumatic actuators are more easily service and calibrated than other types of actuator. Pneumatic actuators can generate substantial thrust to handle a majority of applications, including high-pressure and high-pressure-drop situations. Pneumatic actuators also bleed compressed air to atmosphere, which is environmentally safe, when compared to hydraulics. The main disadvantage of pneumatic actuators is that some response and stiffness are lost because of the compressibility of gases. Pneumatic actuators are available in two main forms; piston actuator and diaphragm actuator. They are available in single acting and double acting features. Smart positioner are available.
