The butterfly valve has been in use since the late 18th century. James Watt used a butterfly valve in his steam engine prototypes. With advances in material manufacturing and technology, butterfly valves could be made smaller and withstand more-extreme temperatures.
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 ...
Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, a flexible diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic , metal or other materials depending on the intended use.
A ball valve is a flow control device which uses a hollow, perforated, and pivoting ball to control fluid flowing through it. It is open when the hole through the middle of the ball is in line with the flow inlet, and closed when it is pivoted 90 degrees by the valve handle, blocking the flow. [1]
An oxygen safety relief valve DN250-safety valves. A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits.
With the factory valve seats, the typical life of the 2.0 L SPI in a Focus is about 100,000 to 120,000 mi (160,000 to 190,000 km), [10] but a failure can happen as early as 70,000 mi (110,000 km). When the valve seat drops out of the cylinder head, it falls into the cylinder and damages the cylinder wall, piston , and cylinder head .
