An adjustable steam flow control for an electric steam iron (10) includes a metering rod (36) mounted in threaded engagement with a support bushing (64) and having a lower end (60,62) that extends into a valve orifice (46) between the water reservoir (20) and the steam generation chamber (32). A pinion gear (54) is secured to the metering rod (36) and engages a spur gear sector (78) on a rotatably mounted steam adjust knob (24). Rotation of the steam adjust knob (24) in one direction or the other by the user causes the metering rod (36) to rotate in its bushing (64) and advance into or retract from the orifice to thus control the steam flow rate. The steam control knob (24) is provided with a spur gear sector (78) so that partial rotation of the steam control knob (24) will rotate the metering rod (36) through its full range of motion.
