Possibility of stainless steel ring.
Our flanged disc check valve is mounted with a cast disc attached to a swinging shaft. On opening, the disc moves away from the seat to allow forward flow and when the flow stops, the flapper returns to the initial position (closed position) and thus blocks the return of flow.
The disc or clapper acts as a shutter and does so thanks to the force of gravity, so it will be important to place them in the correct position since, otherwise, the installation will not work properly and breakdowns will appear.
Its design guarantees a low pressure loss, total flow of fluid and minimum pressure for opening and closing.
Easy maintenance without having to disassemble it from the network, as it allows you to clean and repair or change internal parts by removing the cover and its corresponding screws.
It is the ideal solution to protect against any downstream reflux, to be placed at the end of the network line in ponds, lakes, rivers, water treatment plants, etc. In general, the best place to place it in a system is near the end of the suction tube, inside the tank and opposite where the pump is located. In this way, the installation remains full of water or liquid and does not lose pressure.
Unlike the other two models we have (Fig.13 and fig.13N), this model is built with an assembly length according to EN 558-1 Series 48.
