Abstract
A regeneration valve 131 is adapted for automatic activation of ion exchange resin in a water softener. The regeneration valve includes a switching valve 1, a control valve 32, a water injection valve 54, a cam mechanism (FIG. 13) and a timer mechanism which are compactly integrated in a single valve assembly. The timer mechanism includes a timer motor 80 provided with a switching gear adapted to be switched between 50 Hz and 60 Hz (FIGS. 16, 17). The ion exchange resin layer within the resin reservoir 2 can be uniformly activated so that the regeneration process can be achieved at a high efficiency.
