The self-actuating pipe flap valves prevent undesirable backwash into wastewater pipes in the event of backwater or high water levels. They are made entirely from polymer and so are 100% corrosion-free.
The pipe flap valves are available in various sizes from DN 100 to DN 1000.
The pipe flap is installed in a drainage shaft to prevent the water from flowing back.
Our pipe flaps can protect horizontal pipes up to DN 1000.
Application possibilities
Pipe flaps are used for faecal-free wastewater, for example in seawater and freshwater environments. Here they are used as end pieces in horizontal pipes that lead into shafts or outside.
Area of use for the Multitube backwater valve
The Multitube backwater valve is suitable for use in leaching and pond systems and behind cisterns that are separately connected to a rainwater channel or that lead to a drainage ditch. It provides not only reliable protection against backwater, but also provides additional protection against rats, mice, frogs and vermin.
