ABSTRACT:
A valve is provided with an orifice member that is forcibly inserted into an opening of the valve body and the opening in the valve body is provided with a plurality of protrusions, or ribs, which are shaped and sized to deform in a particular manner during the insertion of the orifice member. The protrusions, or ribs, extend radially inward from the inner cylindrical surface of the opening in the valve body. The deformation of the ribs during the insertion of the orifice member provides sealing at the interface between the orifice member and the valve body and, in addition, rigidly holds the orifice member at a predefined position relative to the valve body and permits this position to accurately determined by using a datum surface during the assembly process.
