Technical description

5-5-20 - 2
Smooth ends
*) Can be connected to smooth pipes with KOMBI compression coupling. See catalogue
leaflet KOMBI.
Kvs = m3/h at a pressure drop of 1 bar and fully open valve.
Handwheel TBV, complete
Setting of a valve for a given pressure drop, eg corresponding to position 5 is done as follows:
1. Check that the scale is in upper position towards the handwheel before setting (fig 1).
2. Turn the handwheel so that position 5 is pointing at the index* of the valve body (fig 2).
3. Push the scale downwards over the bonnet (fig 3). The valve is now set.
There is a diagram for every valve size that shows the flow for different pressure drops and settings.

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.
