Introduction
The Belimo characterized control valve
Belimo adds «characterized control»
to ball valves
In order to ensure good stability of control,
a hydraulic final controlling element
must possess a flow characteristic that
supplements the non-linear characteristic
of the heat exchanger in the HVAC system.
Belimo has succeeded in solving the problem
of the distorted flow characteristic of ordinary
ball valves.
A so-called «characterizing disc» in the inlet
of the characterized control valve converts the
valve’s characteristic to the equal-percentage
kind.
The side of the characterizing disc facing the
ball is concave and in contact with the surface
of the ball. Thus, the actual flow is regulated
by the hole in the ball and by the V-shaped
aperture in the characterizing disc.

Opening position
Characteristic of a Belimo characterized control valve
The kvs value is reduced and corresponds
approximately to that of a globe valve of
comparable size. In order to avoid having to
fit pipe reducers in the majority of cases, each
valve size is also available with an appropriate
choice of kvs values.
Advantages of the Belimo characterized
control valve
• Equal-percentage characteristic
• No initial jump in flow on opening
• Excellent stability of control thanks to the
characterizing disk
Opening position
Characteristic of an ordinary ball valve
The reason for this is that an ordinary ball
valve has an extremely high flow coefficient
(kvs value) compared with its nominal size,
several times that of a comparable globe
valve.
Therefore, an ordinary ball valve is not very
suitable for performing control functions:
• Flow coefficient excessive due to the design
• Flow control inadequate in the part-load
range

Flow rate
Characteristics of an ideal hydraulic final controlling element
An equal-percentage valve characteristic
is desirable in order to produce a linear
relationship between the thermal output and
the opening position of the final controlling
element. This means that the flow rate
increases very slowly as the final controlling
element begins to open.
Unfortunately, this characteristic is severely
distorted in ordinary ball valves.

Optimum choice of kvs valves

• Better controllability
• Lower installation costs
The Belimo range of characterized control
valves includes 2-way and 3-way types. These
are available in a variety of sizes and with a
choice of kvs values.
A characterized control valve is supplied as
a unit complete with a suitable Belimo rotary
actuator.
• kvs values similar to those of globe valves of
comparable size
• Fewer pipe reducers needed
• Better part-load characteristics and less
prone to vibration, greater stability of control
• Tight-sealing (2-way)

Introduction
Project planning
Relevant information
The data, information and limit values listed on the "Characterised control valves" data sheets
are to be taken into account and/or complied with, respectively.
Closing and differential pressures
The maximum permissible closing and differential pressures can be found in the data sheets or
in the documentation "Overview of Valve-Actuator Combinations".
Pipeline clearances
The minimum clearances between the pipelines and the walls and ceilings required for project
planning depend not only on the valve dimensions but also on the selected actuator and can be
found in the data sheets of the valves and actuators.
2-way characterised control valves
Characterised control valves are to be installed in the return as throttling devices. This leads to
lower thermal loads on the sealing elements in the valve. The prescribed flow direction must be
observed.
3-way characterised control valves
3-way characterised control valves are mixing devices. The flow direction must be observed for
all pressure levels. Installation in the supply or return is dependent on the selected hydraulic
circuit.
The 3-way characterised control valve may not be used as a diverting valve
Bypass 70% kvs
Thanks to the reduced flow rate in the bypass, no balancing valve in the bypass line is necessary
with the diverting circuit.

Design and dimensioning
Control characteristics
Design for use with glycol
www.belimo.com
In order to ensure that a valve achieves good control characteristics, thus making it possible to
ensure a long service life for the final controlling element, proper configuration of the valve with
the correct valve authority is required.
The valve authority Pv is the measure of the control characteristics of the valve in conjunction
with the hydraulic network. The valve authority is the ratio between the differential pressure
of the completely opened valve at the nominal flow rate and the maximum differential
pressure occurring with the closed valve. The greater the valve authority, the better the control
characteristics. The smaller the valve authority Pv becomes, the more the operational behaviour
of the valve will deviate from the linearity, i.e. the poorer the behaviour of the volumetric flow
control. A valve authority of Pv of >0.5 is strived for in everyday practice.
Salts were formerly added to the water to reduce its freezing point; this was referred to as brine
applications. Nowadays, glycols are used and one speaks of refrigerant agents. Depending on
the concentration of the refrigerant agent (type of glycol) used and the medium temperature,
the density of the water/glycol mixture varies from 1% to 9%. The volumetric deviation which
results from this process is less than the permitted quantity tolerance of the kvs value of the valve
(of ±10% in accordance with VDE 2178) and need not as a rule be taken into account, even if
glycols require a slightly elevated kv value.
Depending on the type of glycol, tolerance with the valve materials used must be ensured and
the permitted maximum concentration (50 percent) may not be exceeded.

Introduction
Flow characteristics
2-way characterised control valve
Note
As a result of its ball construction, the 3-way
characterised control valve is suitable only to
a limited extent for conventional return line
temperature controls. It is therefore recommended
that return line temperature controls be
implemented as double mixing circuits when these
characterised control valves are used.
The characteristic curve is equalpercentage, with a characteristic curve factor
n(gl) = 3.2 or 3.9. This guarantees stable control
characteristics in the elevated partial load
range. The curve is linear in the lower opening
range between 0 … 30% operating range. This
ensures outstanding control characteristics,
including in the lower partial load range. The
operating range 0 … 100% corresponds to an
angle of rotation of 15 … 90° .
The characterised control valves function as
tight-closing shut-off devices between angles
of rotation of 0 … 15° .
3-way characterised control valve
Same behaviour via the control path A – AB
as with the 2-way characterised control
valves. The flow rate in the bypass B – AB
is designed to be 70% of the kvs value of the
control path (A – AB). The characteristic curve
in the bypass is linear.

The permissible medium temperatures can be found in the corresponding valve and actuator data sheets.
2-way: Leakage rate A, air bubble tight (EN 12266-1)
3-way: Control path A – AB leakage rate A, tight (EN 12266-1)
Bypass B – AB leakage rate class I (EN 1349 and EN 60534-4), max. 1% of kvs value
• For all possible combinations with rotary actuators and their closing pressures and maximum permissible differential pressures, see the document
"Overview Valve-actuator combinations"
