Ball valve - Wikipedia

A full port or more commonly known full bore ball valve has an over-sized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines that require pigging .

LARGE DIAMETER BALL VALVE LEAKAGE - Valve engineering - Eng-Tips

The issue I want to discuss here is that for large diameter ball valves, it seems that is impossible to "conserve" the zero leakage feature of the valve after some time of their installation or use. This is due, in my opinion, to the inertia of the ball that exerts pressure on the soft seats so that after some cycles it causes deformation
