Why consider a pneumatic actuator?
Deciding which actuator is the best for a certain application depends on several factors like environment, required accuracy and closure/open speed. However the main difference between actuators is the thrust or torque they can produce. Here are general applications for the main types of actuators:

Hydraulic actuators: this type of actuator is powered by compressing a fluid like oil, it’s the most powerful and reliable type and recommended for heavy-duty and high load work environment due to the non-elasticity property of the fluid use to power them.

Pneumatic actuators: this type of actuators is powered by compressed gas. It’s suitable for medium-duty and average load work environment and recommended for fast moving, high accuracy applications. Due to the low operating pressures, pneumatic actuators are limited as to the amount of thrust or torque they can generate. Therefore, they are often used to automate smaller valves. High thrust or torque requirements can lead to large actuators.

Electrical actuators: this type of actuators is powered by electric current. It’s suitable for medium-duty and light load work environment and recommended for accurate control. They can be found in industries like food & beverage, pharmaceutical and in heavier industries like mining and power generation.
