HydroSlide® Flow Regulator Type V

Regulating technology, tried and tested
for guaranteed constant discharges – no electricity

The Challenge

Modern management concepts recommend throttling organs with perpendicular flow curve for discharging storm water, combined sewage or wastewater. These organs must provide precise discharge limitations independent of impounding heights in basins, storage areas, overflows, treatment plants and separators.

The Solution

The optimal discharge cross-section is set by a vertical throttle plate that is controlled mechanically by a float arm (rotating to the left, to the right or to the front) whose position is determined by the varying water levels. Thus, a constant discharge of ± 5% is guaranteed. All HydroSlide Flow Regulators are delivered without initial flush (see technical documentation). However, an initial flush is useful for cleaning sewers with light discharges; in such cases the HydroSlide Flow Regulator can be adapted to any required setting. The regulators of the model series DR 200 or smaller have a double valve. A rope pulley is standard for discharges less than 60 l/s to enable manual unplugging. Automatic operation is recommendable for discharges ‹ 25l/s. HydroSlide Flow Regulator opens the whole cross-section, even when a pre-blind has been fitted. All regulators are provided with profiling aid. If the shear stress in the inflow area is not sufficient, a stainless-steel flume can be installed.

The HydroSlide Flow Regulator models VN and VS are fitted with an actuator valve, controlled by a float arm, which closes the plate vertically in front of the outlet. The entire control mechanism is fully protected from outside factors by a housing. Two hand pulleys enable the safe manual opening of the regulator unit’s outlet from above ground in the case of blockage or if upstream flushing is required.

The Advantages

  • no external power source, no electricity
  • simple, robust construction
  • rope pulley – manual opening from above ground (up to and incl. DR 250)
  • control mechanism protected by housing
  • no sole jump
  • without initial flush
  • wet installation avoids separate shaft
  • favourable discharge cross-section during throttling
  • adaptable for other discharge parameters by exchanging disc cam
  • optional: VARIO function for Qab setting
  • optional remote control
