Flexible solution

CEH flow regulators are available with capacities from 65-475 GPM (~4-30 l/s) – see diagram. They are designed for semidry/dry installation.


CEH flow regulators are intended for drainage water containing sewage.


All CEH flow regulators have a replaceable outlet orifice plate enabling adjustment of ± 20% of the in mean size. For capacity changes, please contact Mosbaek North America, Inc.. We identify the regulator by means of its reference number and calculate the dimension of the outlet orifice plate to suit the new capacity.


The CEH flow regulator is characterized by an extremely high braking effect, which makes it possible to control small volumes of sewage water.



Application chart

Excellent control and large orifice opening

In general the CEH flow regulators ensure that the water volume is below that of a throttle pipe at corresponding heads. See the characteristics of the flow controller illustrated on the accompanying graph.


The CEH flow regulators offers hydraulic resistance owing to the patented cascade chamber and the vortex chamber. When the controller is operating, the cascade chamber of the inlet causes a strong contraction of the inlet jet. As a result, the flow resistance is increased, which means that the orifice opening may be increased by 50% compared with certain imitations.



Head-discharge curve for CEH

Low construction, operating and maintenance costs

Definition sketch

CEH flow regulators are designed for semidry/dry installation and installed at the inlet opening. The difference in height between the inlet and the bottom race must be at least 12" (~300 mm). Cast banquettes sloping from all sides towards the bottom race on the outlet side ensure that inspection, service or change of capacity may be carried out under hygienic conditions.


Other features of the CEH regulators are:


  •    Constantly large orifice opening
  •     No moving parts
  •     No electrical components
  •     Made of acid-resistant steel AISI 316L    

These features contribute to low construction, operating and maintenance costs.



Typical applications

Generally, the CEH flow regulators are used in connection with:


  •     Outlets from detention basins
  •     Overflow structures
  •     Inlets of pumping stations
  •     Inlets of wastewater treatment plants
