Pneumatic, Hydraulic, Linear, and Piezoelectric Actuators
Pneumatic Actuators
A pneumatic actuator is a mechanical device that converts compressed air pressure into mechanical motion or force. It’s commonly used in various industrial applications to control valves, dampers, gates, and other mechanical components. Pneumatic actuators are preferred for their simplicity, reliability, and suitability for high-force applications in environments where electrical actuators may not be practical or safe.
