The innovative device Flap valves are used to prevent flooding caused by the backflow of stormwater and sewage. Backflow can be caused by intense rain, thaw or floods. The valves can prevent backflow into residential and commercial premises via the drain systems, toilets or sewers. The flap valves can be installed at the ends of horizontal sewage pipes entering collection wells, cesspits or in drainage pipes leading stormwater to soakaways or rivers. The Drainage Flap Valve comes with a universal coupler allowing it to be installed on drainage pipes or corrugated pipes without holes, from 72 to 100mm diameter.
Dutco Tennant LLC can supply a wide range of Sewage Flap Valves which are made of different materials such as cast iron or ductile iron, depending on the type of application. Sewage Flap Valves can give protection to sewage and rainwater installations vulnerable to flooding. When the small differential pressure is faced by the valve on its back, it automatically opens to allow the discharge to flow through drainage conduits. Our Flap Valves are high-quality units having a premium grade flap which closes against a seal, therefore allowing the unidirectional flow of water. When water begins to flow in the reverse direction, then the flap of the valve closes against the seal. These valves are used to protect the sewage or stormwater tank and the filter unit against contamination from sewage water. If your sewage system is connected to the rainwater system, then you must use Flap Valves to stop the overflow from the stormwater system entering the tank and contaminate it.
We supply sewage water flapper valves which are made up of Cast Iron & Ductile Iron and are fit for use in industrial and residential effluent situations. These valves can also be used for protection in river and sea outfalls. Because of their strong design and rigidity, Cast Iron/Ductile Iron flap valves are demanded the most. We also supply plastic flap valves and stainless steel flap valves.
These sewage water flap valves units fit all standard pipes and are easy & simple to fit. They are easy to maintain and can be opened inline. After installation, you should be able to access these valves for cleaning purposes.
