Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.
Johnson controls makes an amazing solenoid valve for this type of application
A valve which requires pressurised air to operate (open or close) is known as pneumatic valve. A valve has a valve base through which the media (could be be air, liquid, steam, gas...) flows and a actuator mounted on the base which helps operate the valve. This actuator could be of pneumatic type. (or elctrically operated motorised type)
A Bourdon Tube or a Bellows gauge
Pencil type pressure gauge
there are two types of pneumatic comparators. 1 is a back pressure type and the other is the flow velocity type. in back pressure type- comparators use air pressure to sense changes in dimension.
Pneumatic is a type of gas!
Counter type ADCOne of the simplest types of the ADC is the Counter type ADC. The input signal of the ADC is connected to the signal input of its internal comparator. ADC then systematically increases the voltage on the reference input of the comparator until the reference becomes larger than the signal & the comparator output goes to zero.Fig.1 Counter type ADCDinesh Kumar - http://harshit.org
Parallel-comparator (i.e. flash type
Used in trucks and buses. This type of braking system of pneumatic and hydraulic hybrid vehicles.
typically involving compressed air or gases, an example being compressed air lines that power air ratchets
Yes, there are more than one type of pneumatic conveyors out there. Depending on specific needs, you can choose which type of conveyor is right for your business needs.

pneumatic
The back sometimes which are pneumatic tires (containing air) The front is usually a metal cylinder. On some styles, both front and back are metal cylinders which can't flatten but this type is far less common.
Pneumatic = Air! There are brake systems that use a combination of both pneumatic and hydraulic components. In those combination braking systems you would use the hydraulic brake fluid that the manufacture specifies.
