A. There are many benefits in using a Reg-U-Flo Vortex Valve . Firstly the outlet cross-sectional area of a Reg-U-Flo Vortex Valve is typically four times that of an orifice, which should result in a significant reduction in the likelihood of a blockage occurring. Thus maintenance costs and problems are also reduced. Secondly, at low upstream heads experienced in the early stages of a storm the vortex does not initiate. Consequently higher flows are passed forward than were an orifice installed (as the Reg-U-Flo Vortex Valve outlet is larger) and this results in less water being held back in storage. This means that a smaller storage tank can be used with associated cost savings. Typical volume reductions can range from 5 – 30% depending upon the system layout / design storm characteristics.
