A valve is a component for shutting off or controlling the flow of fluids (liquids or gases).
In valves in the narrower sense, a closure member (e.g., disc, plug, ball, or needle) is moved approximately parallel to the direction of fluid flow. The flow is interrupted by pressing the closing part with the sealing surface against a suitably shaped opening, the valve or seal seat.
Other fittings that are referred to as valves, although they do not fall under the above definition, are often soft-seated shut-off devices and check valves (e.g., ball, car, and bicycle valves) in which the seal is achieved by a rubberized closure member or diaphragm (such as in hose valves and pinch valves).
