Clack WS2 CI Noryl Timed Filter Valve Kit – No DLFC

Clack WS2 CI Noryl Timed Filter Valve Kit

The Clack WS2 CI is a heavy-duty 2" top-mount control valve designed for commercial and industrial water filtration applications. This timed filter valve kit is supplied without a DLFC, making it suitable where the drain flow control is to be selected separately to suit the vessel size, media and required backwash rate.

The glass-filled composite valve body provides a robust, corrosion-resistant alternative to metal valves, while the CI electronic controller offers fully programmable regeneration cycles and reliable automatic operation.
