Valves are a type of fittings that are placed in pipeline systems to control and restrict the flow of liquids passing through.

Ball valves consist of a hollow, perforated and pivoting ball that controls the flow of liquids and gases in a pipeline. When the valve handle or lever is rotated or adjusted, it changes the direction of the ball, thus fully opening or fully closing the pipeline system.
