Clack WS1.5SP Control Valve

Quality parts at an exceptional value
Product Description

In 2001, after years of development and extensive field testing, Clack introduced its first line of residential control valves. The goal was to design a family of control valves for the water treatment professional that covered the greatest range of applications, while having the greatest commonality of parts. All Clack valves incorporate patented “stack technology” and feature state-of-the-art electronics and programming software.
