GENERAL AIR DAMPERS
In the next few slides we are going to run through the general
applications of Air dampers, see the terminology of the
actuator parts as well as description of everyday terms used
in the field.
• Belimo as you will know has many applications that we are
capable of motorising.
• Some of them you will know, like Fire Dampers, Control
Dampers and Smoke ventilation Dampers.
• We have been able to use the Belimo motors in other fields
such as Incubators, Fume hoods, windows to name a few.
• By explaining how the motor works and how we were able to
use it in these fields i hope you will see more opppertunity.
• Belimo motors are mostly 90° turning

• We have many adaption's to our products for example we can
add switches or have a square shaft in stead of round or we
can have modulating control.

• We have seen the picture with the labels e have seen the Pics
of the applications we have seen the break down of the part
number now lets look at the terminology of the terms used in
the field:
• RotaryA movement that is in a left to right
movement.
• Linear A movement that is up and down.
• ShaftThe extension of the damper that fits
through the actuator.
• Manual override- The button that allows us to override the
gears so we can move the motor.
• Cable Gland/insert• Mechanical stops-
• NM Torque-
• IP Rating-
The part where the electric cable is
fixed to the motor.
The small metal parts on the motor
that we can adjust to stop the motor
at the required degree of rotation.
The measuring unit to measure the
resistance or force of a specific item i.e.:
damper blade resistance Nm: Newton
Meter
IP rating is the universal protection
rating. IP54 = dust proof IP67 = water
proof
• Housing• Spring Return-
• Modulating-
• Open/Close-
• Thermal Trip-
The out side of the motor
A motor that has a built in spring, the spring is
activated will spring when the power to the
motor is interrupted either by a fire, test or
power failure and cut cables.
A way of controlling the motor to move
according to the requirements of the controller
or the application, we use a 0-10V control
signal. 0V closed 10V Open
A description for a motor that does nothing
other than power open or power close
A device that is placed in the ducting to act as
a sensor for smoke or fire that once tripped will
set a motor into the fail safe function. EG
72°C

• Shaft round-
• Square Shaft-
A motor that has a built in spring, the spring is
activated will spring when the power to the
motor is interrupted either by a fire, test or
power failure and cut cables.
The square hole in the motor that the damper
shaft fits through this is also known as form
fit

SAFETY /FIRE RATED MOTORS
• Safety motors or Fire rated motors are the range of motors
that Belimo has Pioneered and are the market leaders for in
Europe. The Fire Rated motors are motors that abide by the
Standards of the highest safety regulations. Lets look at the
difference between the AF and BF to see the major
differences. Its good to know this as the laws IN SA are
changing and we are starting to meet up with the EU and
American standards for safety.

• As seen in the video smoke is the worrying factor in a
building as it moves faster than fire and is the main cause of
fire related deaths. Up to 80% of all fire related deaths are
from smoke inhalation .
• In SA there are no Regulations as to the specifications of the
fire Damper motors. The SABS only requires that the damper
remain closed for 2 hours at around 300°C.
• The rest of the world (Americas/Europe/Asia) the motor is
part of the Damper application and just as important to
prevent the damper from moving in a safety application.

WATER VALVES AND APPLICATIONS
• Valves in a system can be used for various applications fan
coil units, bypass, shut off, control of hot and cold water.
• Belimo has a variety of valves that we offer Butterfly valves,
Globe valves, Ball valves, FCU valves and PICCV valves.
• By understanding the use and operation of the different
valves you be more comfortable in using them.
PPT-Vorlage
22
• The 3 main types of valves.
• Ball valve A valve that is controlled by a ball in the
body either for open/close or control
• Globe valveA valve that is normally heavy cast iron and
has a linear stroke it’s used for mainly for
controlling the flow of water.
• Butterfly valves- A valve that's main operation is for shutoff
but has been adapted to be suitable for
Control
• Belimo’s 3 way valve are mixing valves which will be
explained in the next few slides.

• As you can see in the 2 way valve (first valve) the water flows
directly through and we can only control the volume of water
in the system.
• In the 3 way valve (second Valve) you see the flow of the
water coming in from 2 ports and leaving the 3rd it works as
follows:
Port A is the cold water port B is the hot water Port AB is the
mixed water.
The cold water flows into the valve and mixes with the hot water
To the correct flow and temperature that is preset by the system
The water then leaves the valve Through port AB at the correct
Flow and temperature to allow for heating or cooling as per the
System requirements.

• As seen in the above diagram you will see the same function
as you saw in the Ball valve the difference between the 2 is
that the ball valve is rotary and the Globe valve is Linear the
Ball valve can only be offered up to 50mm and the globe
valve up to 150mm.
• The operation is as in the Ball valve the water enters through
port A and meets the flow from port B they mix and the
required flow and temperature then leaves through port AB.
