Abstract
A valve assembly has a valve body, a lower bushing, a valve seat, a lower stem, a disc, and an upper stem. The valve body defines a bi-directional flow path therethrough; wherein the valve body has an inner surface, two flange faces, and further defines an upper orifice and a hemispherical lower orifice along an axis perpendicular to the flow path. The lower bushing is housed in the lower orifice, and the lower bushing is configured to tilt within the lower orifice away from the axis. The lower bushing defines a bushing cavity. The valve seat has an outer surface configured to encapsulate the inner surface and the two flange faces of the valve body. The lower stem is housed in the bushing cavity, and the lower stem is configured for tilting away from and towards the axis perpendicular to the flow path. The disc has a seating surface on at outer circumference, defines a stem receptacle to house the lower stem, and the stem receptacle extends less than a diameter of the disc.
