Abstract
A valve orifice insert has a stepped-shaped wall including a first tubular section and a second tubular section having a smaller outer dimension than the first tubular section, and a lip structure protruding axially and including a planar valve seat surface. The first tubular section and the second tubular section being are joined by a step structure. At least one circumferential protrusion extends radially outward a predetermined distance from an outer surface of the first tubular section or an outer surface of the second tubular section to form an interference fit with the step-shaped opening when the valve orifice insert is fitted into the step-shaped opening.
