ACO StormBrixx® represents the ‘Hold’ element of the ACO System Chain; the final stage is ‘Release’. In order to manage the ‘Release’ stage, ACO has a range of flow control systems that regulate stormwater flow before it discharges into the watercourse or sewer networks.
ACO Q-Brake flow controls and ACO Q-Plate orifice plates are capable of regulating any flow for surface water applications and can be used in conjunction with detention systems, such as ACO StormBrixx®, as part of a Water Sensitive Urban Design (WSUD) scheme.
ACO Q-Brake is a horizontal vortex flow control unit designed to regulate stormwater flows. The design of a vortex flow control is based on the fluid mechanics principle of the ‘forced vortex’, which permits flow regulation without any moving parts.
ACO Q-Brake utilises the upstream head and discharge to generate a ‘vortex’ within the mechanism of the unit. The water is then released at a predetermined controlled rate preventing downstream flooding.
Unlike conventional products, ACO Q-Brake is less prone to blockage and permits higher flow at a lower head of water. This is because the vortex control allows an equivalent outlet size 4 to 6 times larger in cross-sectional area to be used.
Each ACO Q-Brake Vortex unit is custom built to suit the profile of the chamber. Radius fixing options remove the need for additional benching, simplifying installation and reducing cost.
 | Flexible fitting options to suit profile of pit wall |
 | Individually configured to suit specific performance criteria |
 | Remote access cable for emergency drain down |
 | Sealing gasket and latch |
 | Regulate stormwater flows from 2 – 100 L/s |
 | Manufactured from Grade 304 stainless steel |
 | Inlet/outlet determined by laboratory verified discharge curves |
If a more conventional product is required, ACO Q-Plate orifice plates are perfect for all flow rates and can be used for a number of applications.
Due to the systems custom construction, any pit size, pipe diameter, orifice opening can be accommodated.
 | Optional remote access cable for emergency drain down (recommended for all orifice apertures less than 100mm) |
 | 4 fixing points to pit wall |
 | Orifice aperture up to 150mm |
 | Manufactured from Grade 304 stainless steel |
 | Sealing gasket and latch |
 | Flat or curved radius to suit chamber profile |
 | Pipe sealing gasket |
