Clack’s automatic valve is a state of the art control head designed for residential and commercial applications requiring flow rates of up to 6.1m3/hr (1”) 7.7m3/hr (1.25”). It has the capability of servicing up to 21” diameter tanks. The valve acts as a primary center that directs and regulates all cycles of water softening or filtration. It can be set to perform regeneration or simple backwash and rinse. The valve comes in different program versions and is controlled by a solid state microprocessor with front panel setting and screen display..
