Overview
VR1 volume flow controller
1 Product overview
VR1 volume flow controllers are maintenance-free, mechanically self-actuating
controllers for supply air and exhaust air ducts with constant flow rates that
operate without any auxiliary power supply. They are used especially at low
flow velocities and variable pressures to keep the flow rate constant as per
the set point value. The flow rate is set using a manual setting device with
pointer, scale and locking mechanism. As an option, the VR1 can be fitted with
a 24 V AC/DC or 230 V AC actuator for motorised set point adjustment for
applications with variable flow rates.
· Highest control accuracy at variable pressures · Factory preset for the set
point flow rate · Adjustable on site · Position-independent installation ·
Maintenance-free design · Sizes DN 80 to DN 315 · Casing tightness: Class C as

Product description
VR1 Volume Flow Controller
3 Product description
The VR1 volume flow controller is made of galvanised steel. The damper blade
which controls the flow rate is centrally supported and has stainless steel
bearing shafts in special bushes. The manual setting device is fitted with a
setting pointer, scale and locking mechanism. Flow rate set points can be
adjusted manually or by actuator within the flow rate ranges min to max. The
special control mechanism ensures high control accuracy, so with variable
pressures, the flow rate can be kept constant over the entire pressure range.
The adjustable volume flow set points depend on the nominal diameter of the
VR1.

3.1 Area of application
The VR1 volume flow controller is used in supply air and exhaust air ducts of
ventilation and air conditioning systems.
Notes · VR1 volume flow controllers are adjusted for the entire scaled
application area. · The flow rate set point is set during installation by
turning the setting pointer to the desired value on the scale and
locking this setting. This does not affect the control accuracy. · Volume flow
controllers that are preset at the factory can be installed directly. The flow
rate set point can be changed at
a later date by releasing the locking mechanism. · The VR1 volume flow
controller and the optional SRC duct silencer are supplied separately.
Assembly is carried out on
site. · Installation and operating instructions for the VR1 are available on
the Internet at www.wildeboer.de.

Product description
VR1 volume flow controller
3.2 Function
The VR1 volume flow controller operates without any auxiliary power supply.
The air flow in the ventilation duct generates a torque in the closing
direction when it hits the damper blade. This torque is counterbalanced by the
restoring torque of a blade spring so that the flow rate can be kept constant
within the tolerances, even if the pressure differences change. Additional
damping bellows ensures vibration-free movement of the damper blade.

The sound power level of the radiated noise can be further reduced by using
acoustic insulation.
The mean sound pressure level in the room is:
· 26 dB lower with acoustic insulation · 8 dB lower without acoustic
insulation
than the sound power levels specified in the nomograms LWA. The sound pressure
level can be further reduced by carrying out additional sound attenuation
measures on site (suspended ceilings, high degree of room attenuation).
However, the acoustic insulation can only achieve the stated values if
connected ventilation ducts are also suitably soundproofed (insulated).
The sound power level of the flow noise can be reduced by up to 25 dB by using an SRC duct silencer. Page 7.

Installation
VR1 volume flow controller
5 Installation
The VR1 volume flow controller is installed regardless of the position and in
the air direction indicated on the label. To ensure lasting functionality and
leak tightness, stress-free installation in ventilation ducts is a
prerequisite.
Space requirement
To enable the scale to be read and the commissioning and servicing work to be
carried out, sufficient space should be kept free in the area of any
attachments. Inspection openings of sufficient size may required so that the
attachments are easily accessible.

5.1 Distances to disturbance points
The stated control accuracy of D applies to a straight and disturbance-free
inflow. Fittings such as bends, branches or changes in cross-section cause
turbulence that can influence the flow rate measurement.
For the VR1 volume flow controller to work optimally, the flows must be
largely free of disturbance. After flow disturbance points (e.g. bends or
branches), the straight inlet and outlet sections shown as examples must be
observed; longer inlet sections may be required where several disturbance
points occur consecutively. Otherwise significant control deviations must be
expected.

· The sound power levels of the flow noise can be further reduced by using the
SRC duct silencer. Further information Page 7
· The sound power levels inside the connecting duct are calculated in the
nomograms as A-weighted overall levels LWA.
· Corresponding octave sound power levels LW-oct for each size and for all
operating points are derived from the Wildeboer dimensioning software WiDim;
likewise the dimensioning with additional SRC duct silencer.
· Important: The sound levels indicated in the nomograms are stated as sound
power levels! They represent the sound energy introduced into the duct system.
They are used for acoustic calculations, e.g. when adding sound attenuators.
· Please note: In many cases, the sound pressure levels Lp or LpA are
specified, which give attenuations of up to 16 dB. When comparing numerical
values, always bear in mind the difference between the sound power level and
sound pressure level. Furthermore, the degree of attenuation is only obtained
with specific connected ducts, deflections, branches and rooms.

Technical Data
VR1 Volume Flow Controller
6.5 Set point adjustment
6.5.1 Manual
In the basic version, VR1 volume flow controllers are designed for manual
adjustment of the flow rate set point and operate without any auxiliary power
supply. The volume flow set point is preselected on an adjusting device and,
with variable pressures, is kept constant to a high degree of accuracy. The
volume flow controllers are adjusted at the factory for the entire volume flow
range.
6.5.2 Motorised
As an option, the set point adjustment can be motorised via factory-mounted electric actuators. Reversible actuators and continuously controllable reversible actuators are available for this.

Reversible actuators (M1, M2) open and close the volumetric flow controllers
with 230 V AC voltage or 24 V DC or AC voltage.
The M1 (230VAC) and M2 (24VAC/DC) actuators enable 2-point and 3-point
control. The corresponding motor limit stops are positioned in order to adjust
the two flow rates. As delivered, the two limit stops of the actuators are set
to the 0 direction of travel and the largest possible angle of rotation. The
maximum angle of rotation corresponds to the largest possible flow rate set
point, and the minimum is equivalent to a “cutoff” at a residual leakage that
is significantly lower than the minimum flow rate. This can be extended to
give 3-point control using an additional 0 circuit arrangement. When operated
in this way, the actuator remains in its current position and the VR1 volume
flow controller adjusts the corresponding set point.
Continuously adjustable reversible actuator (M3) with 24 V AC/DC sets the
volume flow controllers to any desired position. The position is specified by
means of a command signal of 0 or 2 to 10 V, position feedback via an output
signal of 2 to 10 V.
The M3 (24VAC/DC) actuator enables continuous set point adjustment. The
actuator is controlled with a setting voltage of Y = 0 … 10 V DC and moves to
the position specified by the control signal; however, the operating range of
the motor only starts at 2 V. The flow rate set point changes almost linearly
with the setting voltage. As delivered, the actuator is set to 0 direction of
travel and the adjustable mechanical limit stops are set for the largest
possible angle of rotation, which means that when Y = 10 V, the maximum angle
of rotation corresponds to the maximum volume flow set point, and at 0…2 V the
minimum angle of rotation is approached; this corresponds to a “cutoff” at a
residual leakage that is significantly lower than the minimum volume flow set
point. The purpose of the checkback voltage U = 2 … 10VDC is to provide an
electric indication of the volume flow set point setting and to serve as a
subsequent actuating signal for other actuators.
Notes · All the actuators are overload-proof, do not require limit switches, and stop automatically at the limit stop. · In the event of a power failure or interruption, the current actuator position is retained. · The direction of travel of all the adjusting actuators can be reversed via a pushbutton on the motor.
