Abstract: A water control valve designed to control the flow of water from a source to a treatment tank having a plurality of treatment media, thereby providing a supply of treated water, and also provides other cycle controls. For instance, the water control valve directs water to backwash the media of sediment for discharge to a drain, permits regeneration of the media by directing a regeneration agent through the media, directs water through the media in a fast rinse cycle, and directs water to a regeneration agent reservoir for the purpose of refilling the reservoir. The water control valve has six valves and five motors for controlling the valve positions. The valves are fluidly connected to six chambers providing a pathway for water flow between the valves, to a regeneration injection assembly, through a central passageway or a perimeter passageway, to the treatment tank.

Abstract: A water softener valve for controlling water flow to and from a water softener is disclosed that includes a cylindrical shaft extending from said inner surface of a piston chamber that fits into a pressure relief port when the piston is in the service position. The shaft clears the pressure relief port of any debris and closes the pressure relief port during the service cycle. The water softener valve also has a flow meter with at least two helically expanding vanes. A magnet on of the vanes trips a sensor as the turbine rotates, thereby providing means for calculating the flow of water through the valve. The valve also has a flow control button located at an inlet of the valve rather than at the drain, preventing the obstruction of the water flow by regeneration sediment of the tank at the drain. The valve also contains an internal piston port for permitting the free flow of water through the valve during a change in softener cycles.

Abstract: A two-chambered water softener tank with a bi-directional valve for controlling the flow of water between the chamber for use with a water softener is disclosed. The tank includes an outer shell, an upper chamber located within the outer shell containing a redox medium, a lower chamber located within the outer shell and beneath the upper chamber that contains an ion exchange resin, a first port allowing water to flow into the upper chamber, a second port allowing water to flow into the lower chamber, and a third port for allowing water to flow between the upper chamber and lower chamber. The water softener tank also includes a bi-directional valve engageable with the third port for regulating flow of water through the third port from the upper chamber to the lower chamber during service of the water softener and from the lower chamber to the upper chamber during regeneration of the water softener. The bi-directional valve remains open as water flows from the upper chamber to the lower chamber.
