External energy-free flow regulator with
automatic blockage clearance
Modern hydraulic management concepts require throttling devices to be considered. The ideal is where the flow curve is perpendicular providing a constant discharge. Throttling controls are required for foul and surface water systems, for watercourses and river control. These regulating devices are required to provide precise discharge control throughout the regulating range.
The orifice cross section is adjusted to maintain a constant discharge by a vertically operating shutter plate. Our shutter plate is connected to a float arm which relates the water level to a control cam. The precision of the control cam design enables the flow to be regulated to an accuracy of ± 5% from design point. All HydroSlide® Flow Regulators are commonly supplied without a ‘First Flush’ function (see technical documentation); however, a first flush function can be provided for use in foul sewers permitting the initial debris to pass downstream prior to regulating. In such cases, the HydroSlide® Automatic Flow Regulator Type GM can be adapted to any required setting. When a blockage occurs, the regulator will open fully to allow the debris to pass through before returning to its regulating function. Our unit is fitted with a ‘T’ handle to enable manual opening of the unit if desired. When manually opened, the HydroSlide® Automatic Flow Regulator Type GM opens the whole orifice to enable debris to pass through. All regulators are provided with a benching profiling guide.
