As the name suggests the FlowBrake Orifice allows a simple orifice control and is suitable in situations where a varying a peak discharge condition is permitted.
The orifice plate is fabricated from PVC and the orifice designed and fabricated in accordance with BS1042 and can simply be placed within any standard 110mm/160mm socket socket, 110mm/160mm tank grommet or 110mm tank connector.
Since the orifice does not provide filtration, upstream mitigation in the form of combined silt trap and basket filter is recommended upstream of the attenuation tank.
Quoted flows are peak flows at 1.2m head, Cd=0.62 upto 6l/s.
Quoted flows are peak flows at 1.6m head, Cd=0.62 from 8l/s to 10 l/s.
For further info on the use of an orifice plate in SuDS design please get in touch.
