Balancing valves DN 15-50 BALLOREX VENTURI FODRV DN 15-50 BALLOREX VENTURI DRV DN 15-50 Advantages Regulation, isolation and flow measurement in one single unit Measurement across a Venturi nozzle Flow measurement accuracy better than +/- 3% Same measuring accuracy over the entire measuring area from 1 to 100kPa Regulation setting remains unchanged when isolated Can be installed with test points in any position No requirements for straight pipe lengths: up- or downstream BALLOREX VENTURI is a static balancing valve used to regulate flow, measure and isolate. BALLOREX VENTURI is used where there is a demand for a hydraulic balance in a heating or cooling system. This is assured by the distribution of the flow in the pipe system in accordance with the calculated requirement of heating or cooling. BALLOREX VENTURI consists of a regulation and a flow measurement unit where the pressure differential signals are generated. The flow measurement unit is a Venturi nozzle which has a unique construction through which the flow is measured. The flow is calculated based on the pressure differential measured across the Venturi nozzle. The measurement accuracy is better than +/- 3%, and this accuracy is maintained over the entire measurement range from 1 to 100kPa. 15
BALLOREX VENTURI can be delivered in two variations. FODRV: Includes regulation, isolation and a flow measurement unit. DRV: Includes regulation and isolation unit.

EXPLANATION OF FUNCTIONS Regulation The regulation needle is positioned within the isolation ball valve. The opening or closing of the needle controls the flow through the valve. The settings of the needle can be read on the digital scale of the handle where the figure on the black background shows the number of full rotations and the figure on the red background shows the 1/10 rotations. Isolation The valve can be used as an isolation valve. The regulation needle is positioned in the middle of the isolation ball; the isolation function does not alter the setting of the regulation needle. When the valve is installed, it is easy to identify if the valve is open or closed. When the handle is positioned at 90 to the pipe, it indicates that the valve is closed. When the handle is in line with the pipe, it indicates that the valve is open. Flow Measurement Flow measurement is via the Venturi nozzle. The Venturi has two pairs of outlet connections. One set for the high pressure or inlet side and one set for the low pressure or outlet side. The two sets of outlets are sealed from each other using an EPDM rubber O-ring. The pressure differential measured between the two sets of outlets can be used to calculate the actual flow passing through the Venturi. The pressure difference is measured with a BROEN FLOWMETER or equal and is converted to a flow rate in l/s or m³/h either automatically via electronic measuring equipment or manually using the calculation formula.
