FLOW CONTROL QUOTE REQUEST

The Hydro-Valve is a vortex flow control device for throttling the flow rate of stormwater before discharge into a local storm drain or water course.

It is available in a range of sizes with varying flow rates to suit all specifications. It is used to control the flow of stormwater from the attenuation tank preventing downstream flooding during periods of heavy rainfall. Manufactured to customer specifications in order to achieve a specified flow rate at a given head height. This self-activating device uses vortex principles to control and attenuate stormwater flow without the need for moving parts or the need for an external power source.

JFC vortex flow controls are available with a curved back option eliminating the need for the contractor to install vertical benching. The bypass facility is located beyond the controlling orifice of the vortex chamber so should anything block the inlet to the vortex chamber or get inside, operating our bypass will allow the upstream system to be drained down while also possibly saving the need to over-pump.  Due to the location of the Bypass Door, this can also remove the need for a seperate penstock or disk valve.

JFC Hydro-Valve (Vortex Flow Control) is available in a range of sizes with varying flow rates (1 – 50 L/s*) to suit many specifications. *Contact JFC for larger flow rates.

Design:

JFC Hydro-Valves are manufactured to customer specifications and are custom designed to achieve a specified flow rate at a given head height.  It fits into one of the following manhole types depending on the specification

Application:

It is used to control the flow of Stormwater from the attenuation tank preventing downstream flooding during periods of heavy rainfall.

Features & Benefits:

  • Typical Flow rate 1-50L/s*
  • Typical head heights: 450-3000mm*
  • WRc Certification
  • Customised Specification
  • No Moving Parts

Installation:

This unique patented design allows for quick and easy installation to various types of manholes (see above).  The Hydro-Valve is fixed with steel stud anchors to the inside wall of the manhole.  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 JFC Hydro-Valve produces a hydraulic effect to control the flow of stormwater. At low flow rates, water enters through the inlet and passes through the vortex chamber to the outlet without restriction.  As the flow rate increases water enters through the inlet with sufficient energy to create a vortex in the chamber.  This creates a considerable pressure drop between the inlet and outlet restricting the flow to an allowable discharge.  The Hydro-Valve operates automatically with no moving parts or the need for an external power source.
