DefinitionAn <ORIFICE HANDLE> is a <HANDLE> and an <INSTRUMENT COMPONENT> that is a rectangular plate forming part of an assembled <PADDLE ORIFICE PLATE>
The orifice handle is meant to facilitate the installation of the orifice plate between flanges. Generally, the orifice nominal size, flange rating, orifice bore diameter and 'Inlet' is stamped on the upstream side of the handle. For orifice handles which are an integral part, i.e. not manufactured as a separate part and fitted on to the orifice plate, see 'integral orifice paddle'.
