RIEGER offers this variant of the double seat bottom valve as a special feature on the market, in which the function of a diverter valve is also realized.
The advantage over the usual straight-through double-seat bottom seat valves is that the pipeline is not filled when filling or emptying rows of tanks.
The pipe is only open up to the tank to be filled. This avoids an additional risk of contamination from otherwise necessary shut-off valves.
