Abstract

Flow controllers are provided for interconnecting a fluid source to two separate collection zones. The flow controllers include a body having a fluid inlet communicating with the source and two fluid outlets, each communicating with one of the collection zones. An actuator member received within a cavity of the body selectively establishes fluid communication between the inlet and an outlet. In a first position, the fluid inlet is in fluid communication with one of the fluid outlets and the associated collection zone. The actuator member is non- rotationally moved to a second position within the cavity to establish fluid communication between the fluid inlet and the other fluid outlet, thereby halting flow through the first outlet and allowing fluid communication with the other collection zone. An optional safety feature prevents movement of the actuator member from the second position to the first position.
