ABSTRACT:
A bracket for a refrigeration valve includes an elongated flat plate bent in half with the two halves of the plate lying in parallel, adjacent relation. The inner bracket half includes an opening closely receiving the inlet fitting of the valve, and a predetermined internal geometry closely receiving the external profile of a fixed nut on the fitting. The outer bracket half also includes an opening configured to closely receive the fitting, and a dimension such that it butts up against an outer side surface of the nut. The outer bracket half is mechanically fixed to the fitting, such as by riveting, brazing or other means. Fasteners are received through corresponding apertures in the bracket halves to attach the bracket to a support surface. The cooperating geometries of the inner bracket half and the nut prevent the bracket from rotating with respect to the fitting during assembly.
