As we know that valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries ) by opening, closing, or partially obstructing various passageways. Technically,Valves are fittings, but are usually discussed as a separate category because of the wide range of applications and quite diverse of types. When the valve stays open, fluid flows in a direction from higher pressure to the lower.
