STVE DN200-300

Area of use

The balancing valve STVE is used to adjust and
balance the flow in heating och cooling systems.

Description

STVE is a flanged valve. The valve is equipped
with self-sealing measuring points on the flanges
of the valve.
The valve will be set to a flow or kv-value with
help of the wheel. To set the flow correctly use a
measuringinstrument.
To avoid turbulence which can affect the measuring
accuracy, the valve should not be assembled
close to bends, branch lines and other valves
directly before or after the valve according to
the figure. The valve must be assembled with the
flow in the direction of the arrow to achieve the
correct measuring results.
