Abstract
A multi-function, random access, dual, three-way valve for use with fluid switching and the like is provided, whereby a first fluid flow to the valve is selectively placed in fluid communication with a first or a second outlet passage from the valve for selectively transferring the first fluid flow and a second fluid flow to the valve is, independent of the flow path of the first fluid, selectively placed in fluid communication with a third or a fourth outlet from the valve for simultaneously transferring the second fluid flow. A rotor element rotatably movable relative to a stationary stator element to at least four discrete angular positions actuates to multi-function switching capabilities of the valve when the rotor element is selectively placed in one of the at least four discrete positions. The valve directs the first fluid flow to one of two alternate outlet passages and, simultaneously and independently, directs the second fluid flow to one of at least two different outlet passages.
