Product Description

Clack's WS1 Automatic valve is a state-of-the-art control head designed for residential and commercial applications requiring flow rates up to 27 GPM (6.1 m³/hr). It has a backwash abilitiy capable of servicing up to 22" 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 downflow regeneration or simply 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.

The WS1 has 9 injector sizes to choose from for different draw rates.
