110mm Vertically Assembled Anti Flooding Backwater Waste Valve Backflow Prevention

The valve has successfully passed a series of tests required by the EN 13564 standard and received the CE mark.

Like other models the backwater valves mounted vertically operate automatically and reliably, protecting facilities against flooding caused by the back flow of sewage.
