Beschreibung
Zusammenfassung:	A ball valve stopper comprising a spherical contoured body comprising a substantially inelastic first material and having a flow port. A closed face of the spherical contoured body is orthogonal with respect to the flow port and includes a spherical fluid seal area. A rotation support member is aligned orthogonally to the flow port and the fluid seal area. A material discontinuity volume is disposed behind the closed face of the spherical contoured body.
