What type of actuator converts air pressure into linear motion?

A cylinder is an actuator specifically designed to convert the energy from compressed air into linear motion. When air is introduced into the cylinder, it pushes a piston inside the cylinder, creating movement along a straight path. This linear motion is essential in various applications such as in automation systems, where precise movement is required to perform tasks like lifting, pushing, or pulling objects.

In contrast, a motor typically converts electrical energy into rotational motion, not linear motion. Pneumatic valves are devices used to control the flow and direction of air in a pneumatic system but do not create motion themselves. A compressor is responsible for compressing air to create the pressure needed for operation in a pneumatic system; it does not produce motion directly. Therefore, the cylinder is the appropriate choice as it directly achieves the conversion of air pressure into the desired linear movement.
