4.5 Setting the pre-set values
See Figure 5
Balancing valves
1. Set the limiter (2) to the specified pre-set
value (1)
2. Adjust the hand (3) so it rests on the edge
of the limiter (2)
Note! If the pre-set value is C, the valve
functions as a shut-off valve.
4.6 Measuring the valve's flow
rate
The valve's flow rate can be measured using
a separate flowmeter. These devices measure
the pressure on both sides of the valve and
calculate the pressure loss caused by the valve
on the basis of the measurements. The measur-
ing device determines the flow rate based on the
pressure loss and the Kv value corresponding to
the valve's pre-set value. Contact Vexve Oy for
additional information on suitable flowmeters.
