Pneumatic Actuator $68.51 High Quality Content by WIKIPEDIA articles A pneumatic actuator converts energy (in the form of compressed air, typically) into motion. The motion can be rotary or linear, depending on the type of actuator. A Pneumatic actuator mainly consists of a piston, a cylinder, and valves or ports. The piston is covered by a diaphragm, or seal, which keeps the air in the upper portion of the cylinder, allowing air pressure to force the diaphragm downward, moving the piston underneath, which in turn moves the valve stem, which is linked to the internal parts of the actuator. Pneumatic actuators may only have one spot for a signal input, top or bottom, depending on action required. Valves require little pressure to operate and usually double or triple the input force. The larger the size of the piston, the larger the output pressure can be. Having a larger piston can also be good if air supply is low, allowing the same forces with less input. These pressures are large enough to crush object in the pipe. On 100 kPa input, you could lift a small car (upwards 1,000 lbs) easily, and this is only a basic, small pneumatic valve.

Anybody who has ridden a bike with spring coil shock absorbers on hard undulating surfaces would know how different and efficient the damping is on a pneumatic and hydraulic shock. The present day shock is a very state of the art shock and vibration damping equipment that works on either compressed air power or fluids to dissipate the energy and the vibrations generated from tyre contact with road surface. The shock impulse is dissipated through the Pneumatic and hydraulic cylinder with a sliding piston setup inside. The cylinder is filled with a fluid or air, as the requirement might be. Shock absorbers find use not only in the motor and automobile suspensions but in aircraft landing gear, in drilling equipment, in earth moving equipment, in oil rigs and many other huge industrial machineries. The same principle behind shock absorbers is employed in rail transport which limits the yawing of bogies from side to side in a fast moving train.

Pneumatic and hydraulic damping systems contain pneumatic cylinders or hydraulic cylinders which employ a steel piston, a piston rod, a cylinder barrel setup to help deliver the damping effect. As compressed air or fluid moves into a pneumatic or hydraulic cylinder, it pushes the piston up or down through the length of the cylinder. The reflex action of the piston is either activated by either the compressed air or by a spring mechanism, which brings back the spring to its original position. These are also called Single Action Cylinders. Cylinders come in a variety of types and may either be pneumatic cylinders, electro pneumatic cylinder, hydraulic cylinder or electro hydraulic cylinders. Double Acting Cylinders (DAC) employ the force of air to move in two ways, in an extend stroke and a retract stroke. Double Acting Cylinders have two ports, one for outstroke and one for in-stroke.

As the industry requirements may vary, pneumatic and hydraulic cylinders come in a variety of bores and strokes configurations. These may vary between being smaller than an inch all the way up to several feet. The power of compressed air or air may range from a few pounds per square inch to hundreds of pounds creating enough power and force of a few thousands of pounds. The pistons rods are usually made of toughened alloy steel. Cylinder pipes are seamless drawn and are precisely honed to the smoothest finish to prevent corrosion and provide long life for piston-seals.

Valves present inside the pneumatic and hydraulic cylinder help regulate the flow of compressed air or fluids and maintain the pressure inside the pressure inside the pneumatic or hydraulic cylinder. Some pneumatic cylinders reach 1000 mm in diameter, and are used in place of hydraulic cylinders for special circumstances where leaking hydraulic oil could impose an extreme hazard. Pneumatic and hydraulic cylinders also find application in automated shutters in train and tram doors, and automated exits that are monitored and activated by sensors. The low friction nature of arrangement in Pneumatic and hydraulic cylinders enable a smooth, slow-speed operation and at a low pressure which is a safety consideration in human traffic areas.
