RailControl - flushing and inspection shaft

The RailControl flushing and inspection shaft meets all the standards and requirements of the German Federal Railway Authority along with those of Deutsche Bahn AG, and can therefore be used for all pressure ranges of the track system. It is the ideal addition to the practice-proven RailPipe drainage pipe.

The RailControl is available as 180° shaft in two basic designs, each with inlet and outlet in nominal connection diameters DN 250 and DN 400. Standard nominal diameters ranging from DN 150 to DN 300 can be connected using reducers. RailControl with its modular design comprising shaft bottom and extension pipe was specifically developed according to the specifications of DBS 918064. It also features a fully-fledged raceway. The concrete support ring (BARD ring) allows the connection of standard covers 625 mm.

RailControl also features the HPQ manufacturer-related product qualification.
