Innovative and cost effective flow control solutions for stormwater

2gH Solutions is the exclusive US representative for stormwater applications of the Hydrovex® line of products from Veolia Water Technologies Canada.  With over 10,000 installations across the USA and Canada, Veolia Water Technologies Canada is the leading manufacturer and supplier of flow control products to the stormwater industry in North America.

Passive Flow Control

Hydrovex® TTT - Membrane Flow Regulator
The Hydrovex® TTT Membrane Flow Regulator is based on the Bernoulli principle and produces a nearly constant flow rate as upstream water levels rise and fall.  It is an ideal choice for minimizing detention storage volume and flow splitting and can operate at depths up to 16 feet.
Hydrovex® Clari - Regulated Outlet Slot
The Hydrovex® Clari Regulated Outlet Slot operates solely on water pressure and has no mechanically engaged parts. As upstream water levels rise, the Hydrovex Clari’s pre-stressed bending sheet deflects and reduces the area of the slot and maintains the discharge at a nearly constant rate.  It is an ideal choice for minimizing detention storage volume and flow splitting.
Hydrovex® BW Series Bending Weir
The Hydrovex® BW series Bending Weir is hydraulically more efficient than a traditional, fixed weir.  As the upstream water level rises above its crest, the Hydrovex® BW bends downward, increasing the effective head on the weir and increasing the flow rate.  As water levels recede the weir bends back to its initial position.
The Hydrovex® Flap - Spring Loaded Bending Weir is the hydraulically most efficient bending weir in the industry.  Its spring loaded design allows it to deflect at heads as low as 0.05 feet.  It is an ideal choice for flow splitting when head must be controlled in a very limited range. 
Hydrovex ®  VHV/SVHV - Vertical Vortex Regulator
The Hydrovex® VHV and SVHV series Vortex Flow Regulators operate on the forced vortex principle whereby an air core formed at the center of the vortex reduces the effective area of flow through its orifice. This allows the use of inlets which are 4-6 times larger than a typical orifice for the same flow rate.
The Hydrovex® Pond Vertical Vortex Regulator is fitted with a vertical inlet pipe which allows it to operate in full vortex flow mode with very little head over the crest of its inlet.  It’s an ideal choice to improve the hydraulic efficiency of stormwater outlets at minimal cost.
The Hydrovex® IHV is a vortex style flow regulator that provides more precise flow throttling and control.  Available inlet diameters range from 4" to 40", allowing it to cover a large flow range with high accuracy.
The Hydrovex® IHV Euro Style is a vortex style flow regulator designed to be installed in a wet well, and includes an emergency bypass cover.  Available inlet diameters range from 4" to 40", allowing it to cover a large flow range with high accuracy.
The Hydrovex® ARS Air Regulated Siphon offers an excellent alternative to conventional overflow weirs. Storm overflow outfalls using air-regulated siphons are much smaller in size than those using conventional weirs.

Active & Operable Flow Control

The Hydrovex® FluidGate is an economical and light weight control gate featuring PVC and stainless steel construction.  It is ideal for diversions, bypasses and throttling applications which require less precise control.
Hydrovex® HHV-E - Vortex Driven Electronic Regulator
The Hydrovex® HHV-E is a powered and programmable flow regulator for very precise process flow control applications.  Pressure transducers located in the volute detect changes in flow and signal the programmable logic control to open or close a valve accordingly.  It automatically increases flow to clear blockages.
Hydrovex® Turbo - Flow Regulator
The Hydrovex® Turbo very precisely regulates flow at a constant rate and is intended for process flow control applications.  It is equipped with a turbine that self-powers an internal hydraulic circuit which opens or closes a valve in response to changes in flow rate.  Power is transmitted through the hydraulic circuit with and eco friendly bio-degradable vegetable oil.

Check Valves

The Hydrovex® CCV -Circular Check Valve features corrosion resistant 304 stainless steel construction and a Perbunan rubber flap for a watertight seal with much less headloss than traditional cast iron, steel and aluminum gates.
Hydrovex® LCV - Linear Check Valve
Hydrovex® LCV - Linear Check Valve is features corrosion resistant 304 stainless steel construction and a Perbunan rubber flap for a water tight seal through slots and overflow weirs with minimal headloss.

Flow Measurement

Hydrovex® Tipper - Flow Measuring Device
The Hydrovex® Tipper can measure flows from 4 gpm to 80 gpm.  It is equipped with a mechanical counter, or can be equipped with a magnetic limit switch for use with SCADA technology.
Hydrovex® FluidWing - Profiled Overflow Weir
The Hydrovex® FluidWing features a precisely designed shape that allows for flow measurement at very low heads.

Gross Pollutant Separation

Hydrovex® FluidScreen - Oscillating Static Screen
The Hydrovex® Fluidscreen provides a means to maintain flow in the event the screen becomes clogged or blocked, reducing the likelihood of upstream flooding in the event of blockage.
