Zusammenfassung:	A control valve for a fluid treatment apparatus is provided, including a valve body having a control portion and a treatment portion, the portions being separated from each other so that fluid in the control portion is isolated from fluid in the treatment portion. The treatment portion includes a plurality of piston valves reciprocating in corresponding openings defined in a corresponding number of cylinders for controlling water to be treated in the apparatus. Each of the cylinders has a plurality of peripherally spaced, vertically-extending guide ribs configured for facilitating engagement of the piston valves with the openings and for reducing unwanted cavitation.
