Abstract
A valve system includes a motor, a first valve, a second valve, and a controller. The first valve is connected to the motor shaft and is rotatable to an open position, in which fluid flows through a first channel, and a close position, in which fluid is prevented from flowing through the first channel. The second valve is connected to the motor shaft and is rotatable to an open position, in which fluid flows through a second channel from a first end to a second end, and to a close position, in which fluid is prevented from flowing through the second channel. The controller is connected to the motor and can sequentially actuate the first valve and the second valve to create at least a first, second, third, and fourth position.
