Pneumatic actuators, or pneumatic cylinders as they are also referred to, are highly reliable and safe motion control devices that convert energy into rotary or linear motion. How they achieve this is known as the pneumatic actuator working principle and that is what we are going to look at in this article.

These devices are commonplace within industrial applications where the repeated opening and closing of valves is required, including those within potentially hazardous industrial environments. This includes the process and chemical industries where the direct movement and transfer of fluids occurs.

How the Pneumatic Actuator Working Principle Works

The process of how a pneumatic actuator works is known as the pneumatic actuator working principle. Pneumatic actuators come in two forms: Diaphragm and Piston operated. Pneumatic actuators generate operating energy through the efficient use of compressed air. The instrument air builds up force or pressure which applies against the diaphragm or piston. This then moves the valve actuator to position on the valve stem and the result is mechanical motion.

The use of air to power this motion boils down to two factors. The ease of which it can be compressed and absorbed and also its heightened level of safety compared to other gases. For this reason and the fact that the conversion of compressed air into kinetic energy can be controlled to such a high degree, pneumatic actuators are extremely popular devices across the industrial manufacturing landscape.

Different Types Of Pneumatic Actuator

Choice is always good and this is no different within industrial manufacturing and the devices they use. The ability to generate mechanical movement by using energy converted from compressed air has enabled engineers to use pneumatic actuators for a whole host of fantastic applications. Here are some of the most common types:
