Pneumatic flow control

Pneumatic flow control is the use of air as a control medium, or as the controlled medium, in which one medium controls the flow of another.

Pneumatic flow control taxonomy

There are two possible pneumatic flow controls: those that are controlled by pneumatics, and those that control pneumatics.

Pneumatically controlled valves

Pneumatically controlled valves are valves that are controlled by pressurized air. These may include water flow valves that are controlled by compre ssed air.

Pneumatically controlling valves

Pneumatically controlling valves are valves that control the flow of pressurized air. Another medium such as water (hydraulics) or electricity, for example, may be used to control the valves.

In some cases, the valves are operated manually rather than automatically.
