ATW Series

The ATW-Series valve achieves optimum performance using a teflon-coated, lead-free, solid brass piston and corrosion-resistant spacers and seals. This piston design offers long-term operation with minimal maintenance. Tight tolerances and precision machining optimize piston performance, even in challenging environments.

Choose from electronic or mechanical metered regeneration activation. Controls are fully adjustable and easy to operate. The ATW-Series control operates all steps of regeneration for the dual tank configuration, including backwash, downflow brining and slow rinse, rapid rinse, brine refill and downflow service.
