Understanding Double Acting Pneumatic Actuator. Double acting pneumatic actuator are devices designed to convert energy—typically in the form of compressed air—into mechanical motion. This motion, in turn, is used to control a variety of mechanisms, most commonly valves in industrial process systems.
What are Pneumatic Actuators. Pneumatic actuators are devices that utilize compressed air to convert energy into mechanical motion. They function on the principle of fluid dynamics, where pressurized gas provides the force needed to move an element within the actuator—either in a linear or rotary fashion.
In other words, Actuators are used to perform the task of exerting the required force at the end of the stroke or used to create displacement by the movement of the piston. The pressurised air from the compressor is supplied to reservoir. The pressurised air from storage is supplied to pneumatic actuator to do work. pneumatic actuators
The working principles of pneumatic actuators are base on the conversion of compress air or gas energy into mechanical motion. This is done in a few stages: first, a piston is actuate by compresse air and moves within a cylinder; then, it is converted into rotational movement via the Scotch Yoke Actuator; and finally, the rotational movement is ...
