Hydrovex - FluidGate Control Valve

The flow regulation at storm overflows or retention facilities is usually performed with by a flow regulating valve or a calibrated  orifice.  These methods, unfortunately, do not represent optimal solutions, either from a technical or economic point of view.  These  flow-regulating systems are not precise and depend mostly on the pipe roughness characteristics, which can vary over time.  Such  installation can drift of ±15% of the set flow rate over time.  Based on this limitation, the HYDROVEX

FluidGate control valve is particularly well adapted for medium and large flows in CSO’s or storm drains, surface pound reservoirs and retention tanks.

The HYDROVEX FluidGate control valve is made mostly of PVC, with the exception of the operating rod made of stainless steel
and even with its low weight represents a very high mechanical resistance. Its compact design reduces required installation space
and facilitates handling.

The principal characteristics of the HYDROVEX FluidGate control valve are as follows:

• Upstream implementation (water pressure presses the unit on the wall)
• Directly fixed by anchoring on a vertical wall
• Precise and progressive adjustment of flow
• Indication of height of opening by arrows on a graduated scale
• Compactness
• Low height loss
• Rectangular gate section creating a flow opening favoring large flows at low head (risks of overflow reduced compared to a
• circular gate)
• Installation flush to the invert of the chamber reducing accumulations
• Constructed in non-corrosive materials: PVC and stainless steel
• Operation from ground level by operating rod (with, for example, valve key box)
• When working in shallow depth, opening can be regulated with a wedge insert
