A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves may be designed with different patterns depending on which functions they are supposed to achieve or constraints they are supposed to bear.
The technology of the valves doesn't signify the function they achieve on a particular system, but some designs are more adapted to a given usage.
