to control the flow of air fuel mixture
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)
I am guessing you are talking about the air charging valve on the expansion tank. That is to charge air to the top side on the bladder which acts as a cushion and compresses to allow the water to expand due to being heated, preventing the relief valve reaching it`s setpoint and lifting.
There are many things that a valve grinder is used for. Typically, a valve grinder is used for helping a fuel air mixture to come in and to exhaust the burned gasses.
It is not.. A globe , needle , ball valve are used for throttling For expansion either a shock absorber , diaphragm tank or air chamber are used to allow for expansion
air operated- spring return
Air Switching Valve Operation: A circular-stemmed device used to control the flow of air/fuel mixture in and the flow of burned gasses out of the engine.
The Vacuum switching valve controls the EGR Valve.

if you are asking about the air valve on the tire to add/let out air then it is a schrader valve or an American valve
the valve is on lower side of engine near fire wall.
