Free Valve Sizing
 

Full Port ball valves are recommended for processes requiring minimum restriction through piping, shutoff valves, and other equipment. For example, pump inlet valves are often full port valves. Full port valves are also useful in systems handling slurries, viscous fluids and fluids with residues, and where the capacity to pig lines is desired.
