Pneumatic Actuator

A pneumatic actuator is a device that converts energy into motion and is used to control the movement of a valve or other machine component. It is powered by compressed air, which is stored in a tank and released when needed. The actuator is typically connected to a valve stem, which is then used to open or close the valve. The actuator is designed to be highly reliable and efficient, and is used in a variety of industrial and commercial applications. It is also used in the medical field, as it is capable of providing precise control of a valve’s opening and closing. Pneumatic actuators are also known for their ability to provide a quick response time and are often used in emergency situations. In addition, they are relatively inexpensive and easy to maintain.
