The valve acts as a primary centre that directs and regulates all cycles of water softening or filtration. It can be set to perform downflow regeneration or simply backwash and rinse. The valve is controlled by a solid state microprocessor with front panel setting and screen display. The FX100 has 5 injector sizes to choose from for different draw rates.
