generally when hot gasses or air is used to eitherpropel something or is simply being let out valves are simply devices that can create a one way system - like in the human heart the are valves to stop the blood going back into the heart
If you are talking about a pneumatic solenoid valve the function of it is to control the air in and out flow in a pneumatic actuator.
Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.
Pneumatics are systems made purely from air controlled components. ElectroPneumatics are those that are aided by electric, which can alternateve 3/2 and 5/2 valves, among other things.
Electro pneumatic valves are mechanical valves but operated through pneumatic using suitable solenoid coils.
This classification covers establishments primarily engaged in manufacturing hydraulic and pneumatic valves, hose and tube fittings, and hose assemblies for fluid power systems.
I was gonna ask the same question. I cant seem to find the answer for this I believe Formula One engines don't have camshaft, so pneumatic valves work without the cam ? that's why they rev so high
both pneumatic & hydraulic systems are applications of fluid powers
Air. Pneumatic systems use compressed air.
The pneumatic system controlled by electronic systems.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.

Pneumatic is defined as air driven and therefore the two terms are synonomous. However pneumatic is not as frequently used in describing a valve.
