Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve.
Larner–Johnson Valve: needle control valve often in large sizes used in water supply systems; Leaf valve: one-way valve consisting of a diagonal obstruction with an opening covered by a hinged flap; Line blind valve: a thin sheet oriented perpendicular to the pipe. The sheet has a solid end and a flow-through end; sliding it from one position ...
Swirl flap principle in a four-valve engine. A swirl flap is a small butterfly valve fitted to four-stroke internal combustion engines with at least two intake valves.It is installed inside or just before one of a cylinder's two intake ports, allowing to throttle its intake port's air flow, causing a swirl in the other intake port not fitted with a swirl flap.

The valves are opened gradually to match the rising engine speed with a signal provided by the ignition system. The valves are at the full open position at 8,000 rpm. A small black box sends a computed signal to a servo motor that pulls a wire to open the butterfly valves. The V-Boost system adds 10 percent to the top power rating of the base ...
