The Belimo characterized control valve
Belimo adds "characterized
control" to ball valves
Elements of the characterized
control valve
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.
1 Simple direct mounting using a central
screw. The rotary actuator can be
mounted in four different positions
2 Square stem head for form-fit attachment of the rotary actuator
3 Identical mounting flange for all sizes
4 Stem with two O-ring seals for a long
service life
5 Ball and stem made of stainless steel

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
Characteristic of an ordinary ball 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 partload range

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.

• kvs values similar to those of globe

• Fewer pipe reducers needed
• Less prone to vibration, greater stability

• Tight-sealing (2-way)
6 Characterizing disc produces equalpercentage flow characteristic
7 Internal thread connection (ISO 7/1)
8 Forged fitting, nickel-plated brass

9 Vent window to prevent the accumulation of condensation
10 Thermal decoupling of the actuator

Optimum choice of kvs valves
of identical size
• 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.

Opening position
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.
