Overfall weir
made of stainless steel

Overfall weir
made of stainless steel

For optimum regulation of water level heights over a low adjustment height in an open channel or basin inflow. A consistently high sealing performance is guaranteed regardless of the water pressure. Adaptations for special applications are very easy to implement here. For example, the side cheek plates can be equipped with a heater for trouble-free use at the lowest temperatures.
