Non Return Flap Valve
Fits Pipe Diameter: 110mm
MPN: ZBK 110
Drainage Flap valves designed to protect rooms on lower levels against flooding caused by backward flow of storm water and sewage.
Flap valves effectively protect plumbing systems from rats entering the buildings.
These devices are fully self-activating.
Flap valves and drainage flap valves are made from polypropylene of the highest quality with a supplemented regulator which increases the resistance to sunbeams as well as other atmospheric factors. Polypropylene is harmless to the natural environment, resistant to high temperatures (up to 95°C) as well as aggressive chemical agents present in plant protection products.
Flap valves are equipped with gaskets with a brass O-ring which effectively protects against accidental sliding of the device off the pipe.
Flap valves are installed at the end of sanitary sewage pipes entering collection wells, cesspits or drainage pipes leading storm water to ditches or rivers.
