Abstract

A regenerating control system for liquid conditioners includes ball valves positioned and sized so that they do not cause any flow restriction during the normal operation of the conditioner. The valves are operated by low voltage D.C. motors which require power only while moving the valves from one position to another position. An electronics control system and timer control the operation of the valves and require very small amounts of power. Consequently, a battery backup system can operate for extended periods of time when a commercial power outage occurs. A two-piece housing assembly provides improved seals for sealing between the two housing halves and between the housing assembly and the valve.
