How Vortex Flow Control Valves Reduce Flood Risk
Vortex flow control valves reduce flood risk by limiting peak stormwater discharge while allowing excess water to be safely stored upstream. During high-flow conditions, the valve creates a controlled vortex that restricts flow without mechanical components. This self-regulating action protects drainage networks from surges, minimizes flood damage, and supports sustainable urban drainage systems in both new developments and retrofit projects.
By precisely controlling the discharge rate, vortex flow control valves help prevent downstream infrastructure, such as culverts, sewers, and retention basins, from becoming overwhelmed during heavy rainfall events.
