Abstract: An interchangeable orifice wellhead system is disclosed which comprises a flow control valve comprised of a male union, a female union, a valve cap, and an orifice plate. The orifice plate can include a display tab, which visually communicates to the technician the size of orifice plate aperture. Orifice plates having different size apertures can be interchanged within the same flow control valve. In some embodiments, the male union of the flow control valve can be machined or interchanged with another male union to be used with different size orifice plates.
