ABSTRACT:
A water softening system and apparatus utilizes two tanks, one for service and one for regeneration, and a control system operated by soft water flow controls the operation of all valves and the sequences of regeneration. The control system utilizes parallel plate valves for switching from one tank to the next, parallel plate valves energizing the piston moving the switching valves, and a parallel plate valve structure for distributing the regeneration water, as to amount of flow, direction and timing. A two-way to one-way cam structure initiates the operation of a control cylinder which supplies soft water to the metering valve and the regeneration valve as and where needed.
