Pneumatic Components

Pneumatic systems are used extensively in industrial automation and are usually powered by compressed air. Pneumatic systems use actuators such as cylinders that are typically controlled via manual, air-pilot, or solenoid valves, and are designed in when they can provide a lower cost, more flexible, or safer alternative to electric actuators.
