It specifically limits the diverted volumetric flow and protects downstream systems from hydraulic, pollutant, or operational overload.

During normal operation (passively active)

In the event of excessive water flow, excessively high pollutant levels, or other (virtually) freely selectable factors (e.g., usage).

The WCS^® throttle valve with integrated water quality monitoring combines automatic flow regulation with continuous measurement of relevant quality parameters such as pH, turbidity and conductivity.
If defined threshold values are exceeded, the pneumatic gate valve closes automatically and further discharge is halted. This combines discharge control and water body protection in a single system.

The IDM continuously measures the actual volumetric flow rate, whilst additional sensors monitor water quality. The control system compares the measured values with the defined setpoints and limit values and automatically controls the pneumatic gate valve:

Supplied fully pre-assembled and ready for operation, with a weather-resistant enclosure and integrated control cabinet heater.

With the “SINEMA Remote Connect” remote maintenance solution, the PLC can be accessed via the panel at any time to retrieve data or monitor it via the display.
