What is a Pneumatic Actuator?

Pneumatic valves

Simply put, pneumatic actuators, like pneumatic valves, are amongst the most important of pneumatic control devices. The device is often referred to as a pneumatic cylinder and is found in automation systems and machinery in every industry. Pneumatic actuators come in varying styles, sizes, and designs, so it is important to use devices that work best for your specific system and application. Some of the most prized benefits of these systems include their tremendous flexibility and easy maintenance. They are also great because of the almost endless number of applications.

Actuators range in size from extremely compact (for small handling applications) to large actuators (powerful jobs and Rodless design). Each actuator type has unique characteristics and advantages based on the application it works within. Below, we want to highlight the most common types of actuators.

Tie-Rod Cylinders – these actuators are also referred to as profile cylinders, and they are a universal solution that provides precise and regulated forces in applications with high force requirements and long-stroke lengths. These cylinders come in different materials, such as steel, aluminum, and stainless-steel constructions.

Round Body Cylinder – these actuators are great solutions for a wide range of applications. They are highly customizable, lightweight, and affordable. Use these devices because they offer adjustable force controls (ideal for the food industry).

Short-Stroke Cylinders – these devices are up to 50% shorter than a traditional pneumatic cylinder. They provide the same levels of precision, reliability, and concentrated power. Their small size is perfect for machine environments that have limited installation space.
