KARZB160 Backflow Prevention Valve to fit 150 mm (DN150) pipe (pipe outside diameter 168.3 mm)
Backflow Valves prevent backflow automatically and meet EN13564-1:2001. The valve opens to the full diameter of the pipe to reduce the possibility of blockage, and the lid can be removed for maintenance if necessary. A closure lever allows the valve to be locked shut if required.
The Backflow Valve prevents foul water entering properties and protects lower located rooms against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems and in rainwater drainage systems usually caused by intense rainfall or flooding.
