To assess the Hurricane vortex flow control valve system as supplied by Wavin Limited. It is applicable to surface water applications with design flows from 0.67 l/s to 60 l/s, with a hydrostatic head of up to 2.0 m.
The system is designed to control the rate of discharge of surface water from attenuation tanks or other storage. It does this by creating a vortex in the outlet once a defined head of water is reached.
