This causes a flow deviation that increases with small valves, low settings and low differential pressures. Correction for this deviation can be made with the software TA Select or direct in TA-CBI.

Support material Software TA Select: Makes it easy to choose the right balancing valves by taking into account the desired flow, pressure drop and flow rate. Measuring instruments Use the TA-CBI electronic instrument. It is programmed with valve characteristics for TA valves, enabling measured differential pressure to be read off directly as a flow rate.

Diagram 1/2” - 2” Wanted: Presetting for a 1” valve at a desired flow rate of 6.7 GPM and a pressure drop of 3 ft. Solution: Draw a straight line joining 6.7 GPM and 3 ft. This gives Cv=5.9. Now draw a horizontal line from Cv=5.9. This intersects the bar for a 1”...
