Different applications. Different requirements. The right Clack valve for each system.
CHEMSYS offers a wide range of Clack control valves for professional water treatment systems – from proven standard solutions to newer configurations and technologies.
* V1CIUME – Upflow regeneration
Unlike our standard downflow configurations, the V1CIUME uses upflow regeneration, offering an alternative solution for systems where this regeneration method is required.
* CI – Proven professional standard
A reliable and widely used Clack control platform with extensive functionality for water softening and filtration applications.
* CK – Enhanced user interface
Built around a different control board, CK offers a more user-friendly experience with a multi-color dot-matrix display, text-based menu and multilingual interface, while maintaining the trusted Clack valve platform.
* VP – New plastic platform
The new VP15 and VP2 models bring Clack quality into a plastic valve platform. The meter, NHWB and MAV components are also available in plastic – providing a cost-effective alternative to metal versions without compromising on professional water treatment performance.
* VTT – Twin Tank solution
Designed for twin-tank water treatment configurations where system continuity and efficient operation are key.
Whether you need upflow regeneration, an advanced interface, a cost-effective plastic solution or a twin-tank configuration, CHEMSYS can help you select the right Clack valve for your system.
