Butterfly valves are utilized
butterfly valves are utilized in many aspects of our lives. One of the most common examples of a butterfly valve is in the carburetor of a car. In a carbureted car, the “gas” pedal actually operates a butterfly valve that controls the engine’s air intake. When the driver depresses the gas pedal all the way to the floor, the butterfly valve
opens all the way, as described above, to allow air to pass freely into
the carburetor. The carburetor then allows the air, and enough gas to
maintain the proper air-fuel ratio, to pass through the intake valves
into the combustion chambers, where it is ignited by the engine.

A butterfly valve can also be partially opened. When a car is at idle, the valve is open only slightly, allowing just enough air to pass through to maintain the idle speed. When the gas pedal is pressed a little, the butterfly valve opens a little farther, and so on.
