Clack WS1TT Water Softener Control Valve

The Clack WS1TT is a powerful solution for water systems that demand flexibility and precision. It features a solid-state microprocessor with an easy-to-navigate front panel for simple setup and operation.

With four ways to initiate regeneration (meter immediate, meter delayed, time clock delayed, or pressure differential) you can fine-tune performance based on real-world usage. The system also allows programming in ppm, French degrees, German degrees, or cubic meters to match your specific measurement standards.

This valve supports up to nine programmable regeneration stages, with adjustable cycle times for each phase. A built-in day override feature, adjustable from 1 to 28 days, adds an extra layer of reliability.

Whether you’re running a high-capacity softening system or managing variable flow rates, the WS1TT provides the control you need with the dependability you expect.
