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)
Pneumatic is defined as air driven and therefore the two terms are synonomous. However pneumatic is not as frequently used in describing a valve.
A pneumatic spool valve usually has two sets of atleast one but possibly more rubber o-rings which does indeed need lubrication to function properly.
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.
Johnson controls makes an amazing solenoid valve for this type of application
The five ways to shift a four-way valve are: a) manual b) mechanical c) pneumatic d) hydraulic e) electrical
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.

Electro pneumatic valves are mechanical valves but operated through pneumatic using suitable solenoid coils.

A Bistable Pneumatic Valve is typically a pilot valve that is a 3 ported 2 position detented valve. The valve retains is position during loss of power. this can be accomplished with a mechanical detent and 2 solenoids or a :mangna lath magnetic latch with a polarity sensitive coil. Positive opens and negative closes or vice versa.
The speed of a pneumatic motor is controlled by regulating the flow of intake air with a proportional control valve Paul Berbakov
Pneumatic control valves operate using instrument air to regulate the flow of fluids within a system. The valve's actuator receives compressed air, which moves the valve stem to open or close the valve as needed. This allows for precise control of fluid flow and pressure in various applications, such as process control in industries. The use of pneumatic control enhances response times and allows for remote operation of the valves.
