Pneumatic Actuators marked the difference providing solutions for the flow control automation systems in valve operating systems. Pneumatic energy responding quickly is desirable converting energy into either linear or rotary motion. As a inventor of the pneumatic valve terminal, festo have become an expert in valves. This ranges from simple, low cost applications to the complex automation tasks. It has the right valve and said to be manifold for every purpose. You can get large collection from here. Pneumatic cylinder are known as air cylinders, these are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Like hydraulic cylinders, something forces a piston to move in the desired direction.
