Clack WS1EE Control Valve
Programmable 1” electronic metered valve with LCD display, multiple regeneration options, and double backwash function for efficient softening and filtration control.
Description
The Clack WS1EE Control Valve is an advanced, electronically metered 1” control valve engineered for precision water softening and filtration applications. It combines Clack’s reliable Noryl® valve body with smart microprocessor technology to ensure consistent, efficient, and user-friendly operation.
The WS1EE features four selectable regeneration methods—meter immediate, meter delayed, time clock delayed, and pressure differential—to suit a wide range of system requirements. Its bright front-panel display provides real-time data, including flow rate, volume remaining, totalizer, and days to next regeneration.
This model offers fully adjustable cycle times, an optional double backwash feature, and post-treated water refill for optimal cleaning performance. Built to handle flow rates of up to 27 GPM, it is ideal for residential, commercial, and light industrial water treatment systems.
