Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

A valve is a device or natural object that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, which describes the moving part of a door, in turn from volvere, which means to turn or roll.
