A globe valve is a type of valve used for regulating flow in a pipe, consisting of a movable disk-type element and a stationary ring seat in a spherical body. Usually the globe is moved in and out of the flow by a handle connected to a threaded stem.
A ball valve is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole in the middle so that when the hole is lined up the input side and the output side of the valve, flow occurs.
A butterfly valve has a round plate in the center of the pipe. The plate has an axel connected to an opening lever on the outside of the valve. Turning the lever positions the plate parallel or perpendicular to the flow and thus lets more or less fluid pass.
