The alignment mechanism comprises at least one alignment assembly having an alignment port disposed in the valve body in the pressure reducing section. The port has a passageway passing through an outer wall of the valve, and has a removable closure member adapted to close one end of the passageway. A removable alignment rod is adapted to be inserted through the passageway in the alignment port to contact an outer surface of the diffuser when the diffuser is inserted into the internal cavity of the pressure reducing section of the valve.
