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.

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.
