ACO Q-Brake Vortex - stainless steel stormwater flow control device
ACO Q-Brake Vortex is a horizontal vortex flow control unit for regulating stormwater discharge to prevent downstream flooding. Made from grade 304 stainless steel, it is self-activating, low-maintenance, and custom-built to suit site-specific flow rates from 2–100 l/s and design heads up to 3m. Suitable for new and retrofit drainage schemes, it
Hydro-Brake Optimum - self-activating vortex flow control
Hydro-Brake® Optimum is a self-activating vortex flow control with no moving parts and no power requirement. It is used to control the forward flow of water in both surface water applications and foul / combined applications to prevent flooding. With no moving parts and no power requirements, the Hydro-Brake® Optimum provides reliable
Hydro-Brake® Flood - vortex-controlled solution to fluvial flooding
Hydro-Brake® Flood is a vortex-controlled solution to fluvial flooding. It has no moving parts and no power requirements and is therefore low-maintenance. Ideal for controlling very large river and watercourse flows; from dispersed storage and control schemes with pass forward flow rates of just a few litres per second, to major dams controlling
SDS vortex flow control for stormwater management system
The SDS vortex flow control is used to control the rate at which water is released from a stormwater storage system to downstream drainage systems. It is a self-activating device which controls the rate of water release by inducing a vortex motion. No external energy supplies are needed and it contains no moving parts. Units are equipped with a
