For optimal operation, any air in the water must be removed.
In order to ensure measuring accuracy, the balancing valves with flow
meter must be installed by keeping a straight section above them at least
as long as five diameters, increased to at least ten diameters if the nearest
device upstream is a pump.
The valves must be installed so that:
- the direction of the flow agrees with that of the arrow on the
valve body.
- there is easy access to the flow meter valve, control stem and dial
with the calibration adjustment range.
The valves can be fitted on either vertical or horizontal pipes.
