ABSTRACT:
A mechanized orifice fitting mechanism is provided having a body structure forming an internal chamber and an access opening that is closed by means of a quick disconnect closure. Internally of the body is provided a cam actuated orifice plate ejector and sealing plate which is movable to control positioning of a removable orifice plate in relation to a flow passage extending through the body. Mechanically energized sealing elements are adapted to seal either the orifice plate or the ejector plate and thus permit depressurization of the body to permit insertion and removal of the orifice plate without depressurizing the flow line to which the mechanized orifice fitting is connected.
