Description The Hydro-Valve is a vortex flow control device for controlling stormwater flow to a specific rate before discharge into a local storm drain or water course. Sizes are available between 1 – 50 l/s depending on specification. Contact Drainstore for larger flow rates. Features & Benefits... • Customised Specification • No Moving Parts • Self Activating • Self Cleansing • Manual By-Pass • Easy Installation • 3-6 Times Greater Orifice CSA • Hydraulic Data Available • Full Scale Testing Design... JFC Hydro-Valves are manufactured to customer specifications and are custom designed to achieve a specified design flow rate at a given head height. The units are designed to fit into one of the following manhole types depending on specification. • Ø1200mm • Ø1500mm • Ø1800mm • Rectangular Manhole Operation... The HYDRO-VALVE is a device for controlling stormwater flow by hydraulic effect without requiring moving parts. At low flow rates, water entering through the inlet passes through the vortex chamber to the outlet with no restriction. As flow rate increases water enters through the inlet with enough energy to create a vortex in the vortex chamber which results in a considerable pressure drop between the inlet and the outlet restricting the flow to the allowable discharge. The Hydro-Valve therefore operates automatically with no moving parts and no external power source. A typical application of this valve is to control the flow from storm water attenuation tanks preventing downstream flooding during periods of heavy rainfall. Quality Assurance... JFC Hydro-Valves are manufactured to ISO 9001:2000 quality assurance system.
