ABSTRACT:
A float-actuated, level control valve especially suited for controlling liquid flow into and out of brine tanks of water softening systems. A magnet-operated ball check inside a flow chamber selectively closes ports of the chamber to interrupt liquid flow. Movement of the magnet and operation of the ball check is controlled by a pair of floats so that the valve is opened and closed in response to changes of liquid level. The relative position of the floats can be adjusted to vary the amount of liquid drawn out of the tank, while maintaining a constant maximum level when the tank is filled.
