A valve assembly is disclosed with a housing having generally collinear inlet and outlet ports in the side walls thereof and an interior annular face about each of the inlet and outlet ports. The housing is made of a first metal with a yield strength. The assembly also has a chamber disposed between the inlet and outlet ports, wherein a vertical axis of the chamber is normal to longitudinal axes of the inlet and outlet ports. An annular groove is disposed about the interior annular face of the inlet port and the interior annular face of the outlet port. A second metal is disposed within each of the annular grooves, the second metal having a yield strength greater than the yield strength of the first metal.
