<p>An improved brine valve assembly for control of the brine used to regenerate ion exchange material. The brine valve assembly includes a float valve arrangement for closing and sealing the inlet port when a predetermined low level is reached in the brine tank. The float valve is positioned to float within a float cage immediately prior to its sealing of the inlet port. The level of liquid within the cage is controlled through a tube having a lower end in communication therewith and an upper end in communication with the interior of the brine tank. The elevation of the upper end is adjustable to control the amount of brine drawn during each regeneration cycle. An alternative embodiment of the invention discloses a unique float construction which uses the weight of the brine to insure a better air shut-off.</p> |
