ABSTRACT:
A flow control valve for multicycle liquid treatment apparatus has a pair of rotatable, slotted circular discs at its opposite ends. Rotation of the discs causes the slots to be selectively aligned with various ports, passages, holes and channels so as to control the direction and duration of liquid flow during the different cycles of the apparatus.
