Hydro-Valve Vortex Flow Control:<< Back to JFC Civils |
Storm Water Flow Control 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 –200 l/s depending on specification.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 |

Installation  JFC Hydro-Valves unique patented design allows for quick and easy installation onto various types of manholes (see above). The unit is fixed to the inside wall of the manhole with a number of steel stud anchors. A manual by-pass is also incorporated in the valve for remote operation in the unlikely event of a blockage. |

| Quality Assurance JFC Hydro-Valves are manufactured to ISO 9001:2000 quality assurance system. |
|||||
| 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. |
