Abstract
A converter valve allows product dispenser operator to change from a first fluid source to a second fluid source without fluid crossover. The converter valve includes a first port in fluid communication with a dispense point, a second port in fluid communication with a first fluid source having a first fluid, and a third port is in fluid communication with a second fluid source having a second fluid. The converter valve includes a passage between the first and second ports, and a plug in fluid communication with third port. The second and third ports of the converter valve are disposed symmetrically about the first port, and, accordingly, the converter valve is rotatable about the first port. As such, the converter valve delivers the first fluid to the dispense point, and delivers the second fluid through the passage to the dispense point when the converter valve is rotated.
