Product Description

For the full bore valve, the bore diameter i.e hole in the ball has the same internal diameter as the pipe, whereas a reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on.

Full-port ball valves are used where their low flow resistance is of value such as on pump suction pipes, where a pressure drop can affect pump performance. They are also used in flows containing mixed liquids and solids where flow restrictions can cause separations in the materials causing buildups and thus reducing the flow in the pipes.
