Series 130 - Manual Balancing Valve
by Altecnic
The Altecnic 130 is a fixed orifice double regulating valve (FODRV) which uses a venturi to measure the flow of liquid passing through the valve. A venturi is a fixed orifice device consisting of two different diameters with a tapered section between them. The smaller diameter is referred to as the throat. The venturi is able to accelerate the fluid velocity generating a measureable pressure loss or signal from which a flow co-efficient factor Kvs can be calculated.
From this co-efficient the flow rate passing the valve can be calculated or using the signal the flow rate can be read off the appropriate flow chart, available from Altecnic. The venturi is located upstream of the double regulating valve which provides stable flow measurement during flow regulation. This also makes the valve quieter as the flow passes through the valve.
