Practical example I
The Hydrass Valve
The Hydrass Valve or “Berlin flap“ is composed of a plate that is mounted to a metal frame, which is adjusted to the sewer profile. The length of the rotation axis can be freely selected. According to [Loren1998], it should be at the same level as the dry weather/water flow.
