[. . . ] Habedo®-retrofit reverse rinsing fine filter for D06F pressure reducing valves Product specification sheet Application Habedo® FN09S retrofit reverse rinsing filters are suitable for retrofitting to existing D06F pressure reducing valves. [. . . ] When in the , , filtering" position, the small upper filter is closed so that the water can only pass through the main filter from outside to inside. When the ball valve is opened for reverse rinsing, the filter is pushed downwards until the water supply to the outer side of the main filter is stopped. Simultaneously, the water flow is opened to the upper part of the filter. The water needed for cleaning the filter passes through the upper sieve, the rotating impeller and the main filter from inside to outside. By this means, the filter is fully cleaned over its whole surface area at the full inlet pressure. The filter automatically switches over to the operating position when the ball valve is closed again. Options FN09S-. . . A* = FN09S-. . . AN** = FN09S-. . .
