Abstract
A dual valve construction partners first and second valve portions with a mechanical linkage such as gears to operably couple the control stems together. The gears need not be identical and in fact a first gear may have flats so that motion of the first gear need not always move the second gear proportionally. Furthermore, the gears may have differing gear ratios at different portion of the gears.
