Q-Brake Vortex

Controlling the release of stormwater

ACO Q-Brake Vortex is a horizontal vortex flow control designed to prevent downstream flooding by controlling the release of stormwater before it discharges into the watercourse or sewer. Available as a model in Microdrainage, Site3D and Causeway Flow Hydraulic Design software, it has many water authority approvals.

Custom built to suit the site requirements
Available from 2-100 l/s and up to 3m design head
Manufactured from grade 304 stainless steel
All parts welded to BS 4872
Available with curved or flat back
Attenuation volume required reduced
Larger clear opening, than traditional orifice plates, reduces risk of blockage

Parameters to quote

Each ACO Q-Brake Vortex and ACO Q-Chamber is individually configured to suit the specific performance criteria and the profile of the chamber.

ACO Q-Brake: design head (m) & flow rate (l/s)
ACO Q-Chamber: depth to invert / diameter of the chamber / number of pipe connections / diameters of pipe connections

NEW QuAD-VFC Design Tool

QuAD-VFC is a free cloud-based software that supports the design and specification of ACO’s Q-Brake and Q-Plate range. QuAD-VFC calculates vortex flow control dimensions to achieve required head and flow rates. Offering instant calculations, the tool helps to speed up specification by taking into account parameters such as chamber design and outlet dimensions.
