Flow deviation at different settings
*) Position
Try to avoid mounting taps and pumps, immediately before the valve.
When
∆
p and the design flow are known, use the formula to calculate the Kv-value.
Software
TA Select:
Makes it easy to choose the right balancing valves by taking into account the desired flow and pressure drop.
Measuring instruments
Use the balancing instrument TA-CBI or measuring instrument TA-CMI. They are programmed with valve characteristics for TA
valves, enabling measured differential pressure to be read off directly as a flow rate.
For further information on TA-CBI and TA-CMI, see each catalogue leaflet.
Conversion disc
By using the conversion disc it is easy to calculate the relationship between flow, pressure and setting values for all valve sizes.
