ABSTRACT:
The specification discloses a valve including a valve body with a longitudinal central passage therethrough. A truncated ellipsoid valve member is located within the central passage of the valve body. The ellipsoid member has major and minor axes and has an aperture extending along the major axis thereof. Annular resilient seats are disposed in contact with opposite end portions of the ellipsoid member. A handle is provided to rotate the ellipsoid member between open and closed positions. In the open position, the aperture through the ellipsoid member is aligned with the central passage of the valve body and the ellipsoid member causes deformation of the resilient seats to prevent leakage of fluid around the exterior of the ellipsoid member.
