PRODUCT DESCRIPTION
Balancing valves Fig.221 are globe valves with threaded connections and an oblique body. They are used for
medium flow control. The medium flows in the direction indicated on the valve.
Differential pressure measurement takes place in m
easuring orifice
. The advantage of this solution is, inter alia,
the possibility of direct flow measurement. Kv factor of the m
easuring orifice
, where the measurement of the
differential pressure is made, is constant and does not change during flow adjustment. In practice, this means that we
can balance the system much more easily and faster. When measuring the flow rate, Kv is entered to the measuring
device only once (for the specific m
easuring orifice
), and then the flow can easily be adjusted by observing the varying
flow on the measuring device. In this way making a flow adjustment is easy and very accurate.
