bgu - Balance Regulator
The most important functional elements of the Balance Regulator regulator are the pivoted radial gate, the weighing trough and the regulating weight. These remain in the rest position during low discharge periods with the pivoted radial gate in the fully open position. As the influent discharge increases, it flows through the regulator housing into the weighing trough. The increasing weight and force of the water pushes the weighing trough down and the regulating weight up. Both movements are transferred to the pivoted radial gate by means of coupled levers which initiate the regulating process. As the force of the water on the weighing trough increases, the pivoted radial gate closes thereby decreasing the discharge opening. The Balance Regulator regulator opening is automatically adjusted to match the upstream water level, resulting in a constant regulated discharge.
If a blockage occurs, then the flow through the regulator decreases, resulting in a corresponding decrease of the regulating force on the weighing trough. At this point, the weighing trough rises thereby causing the sectional gate to open automatically and fully. This causes the blockage to be flushed out under the pressure of the upstream water level (flush-out effect) after which the regulating process resumes.
For installations where high downstream water levels are a problem the Balance Regulator balance regulator may be equipped with a backflow prevention system.

Application:
The time-proven Balance Regulator balance regulator operates on the simple and reliable principle of the balance, effectively utilizing the water’s internal energy, and does not require a float. The Balance Regulator regulator is a true regulation system.
Independent of the headwater storage height, the Balance Regulator maintains the discharge at a given constant value. Based on the automatic self-flushing effect, it ensures high discharge accuracy and reliability. With a discharge range of 16 - 4,000 gpm (1 - 250 L/s) the balance regulator is well suited to accurately regulate very small to medium discharges.
The Balance Regulator regulator may also be remotely controlled and therefore its’ discharge may be modulated over a broad range.
Balance Regulator Regulator Discharge Calibration
The Balance Regulator regulator has been calibrated on a fully functional, full scale test stand. It has undergone hundreds of calibration tests so that each regulator size is fully defined. Each Balance Regulator regulator is shipped to site pre-set to the desired design flow. In addition, set points are clearly indicated for future in-situ flow adjustments (should it be required). The regulator can then be installed and put into operation without requiring time consuming and cost intensive in-situ flow calibration or measurement.
Balance Regulator Regulator with Servo-Control
The Balance Regulator regulator can be remote-controlled by equipping or retro-fitting with an electric servo-control system. An Balance Regulator equipped with a servo-control unit can be varied from fully open (ON) to fully closed (OFF), either manually on-site or from a remote, central control location. In case of power outages, the regulator will continue to operate automatically maintaining the constant discharge it was last set at.
