The first carburetor butterfly valve was invented by Carl Benz in 1893.
The only butterfly valve I am aware of is in the carbuerator and contols air flow. Few cans still use this item.
A ball valve is a ball with a hole through it that rotates around its axis to expose the hole for flow or the solid wall of the ball for no flow. The butterfly valve is a flat piece that is supported in the middle by a shaft that opens or closes when the shaft is rotated.
The solenoid was invented by Andre-Marie Ampere (1775-1836).
Butterfly valve refers to a kind of valve whose closing part (butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The butterfly valve is usually 90° from fully open to fully closed. The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The advantages of the gate valve: small fluid resistance, less effort to open and close, no restriction on the flow of the medium, no turbulence, no pressure reduction
it was invented by a man called Justin Andrews . valva lag- inlet valve closes after B.D.C -exhaust valve closes after T.D.C
because this valve has a centric line through it, and control by a stem going through the disc and drive it open just like a wing of butterfly, that is why it is called butterfly valve
A butterfly valve is from a family of valves called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage. The position of the disc is effected from outside the valve. gas butterfly valve is one kind of butterfly valve, the main feature is that all the functions are supported by gas just as the Electric Butterfly Valve which supported by electric.

No-one invented the butterfly, but a combination of a moth and catapiller gave it, the fact it first looks like a catapiler, then turns into a butterfly .
Globe is used for throttling
1834
The throttle position sensor is a device that signals the position of the butterfly valve of the throttle body. The throttle body is the part that is between the air intake and the intake manifold. Disconnect the air intake from the throttle body then have someone press the accelerator pedal. Watch the butterfly valve open and close as your assistant presses down and lets up on the pedal and you should see the butterfly valve moving. On the end of the rod that passes through the butterfly valve should be a sensor that detects the position of the butterfly valve. THAT is the TPS. There will be an electrical connector.

The use of butterfly valves for control applications is limited to the valve opening range between 30 degrees to 70 degrees. Throttling using butterfly valves is limited to low pressure drop applications. Potential cavitation is a concern when butterfly valves are used. Also possibility of a choked flow is a concern.
