Clack WS1 Water Softener Control Valve

Take control of your water softening system with the Clack WS1, engineered for reliability and precision.

Featuring a solid-state microprocessor with an intuitive front panel, the WS1 offers effortless programming and diagnostics. With three flexible operating modes (meter immediate, meter delayed, or time clock delayed), it adapts to the flow demands of your facility.

The double backwash feature ensures thorough media regeneration and cleaner, more efficient performance over time, which is ideal for commercial or industrial water softener systems dealing with fluctuating hardness levels.

Built for customization, it supports 36 pre-programmed regeneration cycles, and includes a day override (1–28 day range) for added backup when water use patterns change.

Whether you’re installing new or upgrading old, the WS1 delivers dependable control with just the right amount of “set it and forget it.” It’s a smart, rugged choice for any business that can’t afford downtime due to water quality issues.
