Abstract:
An alignment mechanism is used for assembly of a diffuser inside a pressure reducing and conditioning valve, said valve having a body, an inlet port, an outlet port, a pressure reducing section between the ports, and a diffuser in an internal cavity of the pressure reducing section. 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 to 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. A method of use of the alignment assembly is disclosed.
