Mode of operation
The final controlling device is comprised of three components: characterised control
valve (CCV), measuring pipe with volumetric flow sensor and the actuator itself.
The adjusted maximum flow (max) is assigned to the maximum positioning signal
(typically 10 V / 100%). The final controlling device can be controlled communicative
or analogue. The medium is detected by the sensor in the measuring pipe and is
applied as the flow value. The measured value is balanced with the setpoint. The
actuator corrects the deviation by changing the valve position. The angle of rotation α
varies according to the differential pressure through the final controlling element (see
volumetric flow curves).

Heat exchanger transmission behaviour
Depending on the construction, temperature spread, medium and hydraulic circuit,
the power Q is not proportional to the water volumetric flow (Curve 1). With the
classical type of temperature control, an attempt is made to maintain the control signal
Y proportional to the power Q (Curve 2). This is achieved by means of an equalpercentage valve characteristic curve (Curve 3).

Control characteristics
Electr. 2-way PI-CCV EPIV, Flange, PN 16
The velocity of the medium is measured in the measuring component (sensor
electronics) and converted to a flow rate signal.
The positioning signal Y corresponds to the power Q via the exchanger, the
volumetric flow is regulated in the EPIV. The control signal Y is converted into an
equal-percentage characteristic curve and provided with the Vmax value as the new
reference variable w. The momentary control deviation forms the positioning signal Y1
for the actuator.
The specially configured control parameters in connection with the precise flow rate
sensor ensure a stable quality of control. They are however not suitable for rapid
control processes, i.e. for domestic water control.
U5 displays the measured volumetric flow as voltage (factory setting). As an
alternative, U5 can be used for displaying the valve opening angle. It is always in
reference to the respective Vnom, i.e. if Vmax is e.g. 50% of Vnom, then Y = 10 V,
U5 = 5 V.

Flow control
Vnom is the maximum possible flow.
Vmax is the maximum flow rate which has been set with the greatest positioning
signal. Vmax can be set between 30% and 100% of Vnom.

Given the very low flow speed in the opening point, this can no longer be measured by
the sensor within the required tolerance. This range is overridden electronically.
Opening valve
The valve remains closed until the volumetric flow required by the positioning signal Y
corresponds to 1% of Vnom. The control along the valve characteristic curve is active
after this value has been exceeded.
Closing valve
The control along the valve characteristic curve is active up to the required flow rate of
1% of Vnom. Once the level falls below this value, the flow rate is maintained at 1% of
Vnom. If the level falls below the flow rate of 0.5% of Vnom required by the reference
variable Y, then the valve will close.

Connection option for a sensor (active sensor or switching contact). The MP actuator
serves as an analogue/digital converter for the transmission of the sensor signal via
MP-Bus to the higher level system.
The factory settings cover the most common applications. Single parameters can be
modified with the Belimo Service Tools MFT-P or ZTH AP.
This can be inverted in cases of control with an analogue positioning signal. The
inversion causes the reversal of the standard behaviour, i.e. at a positioning signal of
0%, regulation is to max, and the valve is closed at a positioning signal of 100%.
With the Belimo tools, the maximum flow rate (equivalent to 100% requirement) can
be adjusted on-site, simply and reliably, in a few steps. If the device is integrated in the
management system, then the balancing can be handled directly by the management
system.
Manual override with push-button possible (the gear is disengaged for as long as the
button is pressed or remains locked).
The actuator is overload protected, requires no limit switches and automatically stops
when the end stop is reached.

Installation in the return is recommended.
The water quality requirements specified in VDI 2035 must be adhered to.
Belimo valves are regulating devices. For the valves to function correctly in the long
term, they must be kept free from particle debris (e.g. welding beads during installation
work). The installation of suitable strainer is recommended.
The water must exhibit a conductivity ≥ 20 μS/cm during operation for correct
functioning. It should be noted that, under normal circumstances, even filling water
with a lower conductivity will experience an elevation of its conductivity to above
the minimum required value during filling and that the system can thus be put into
operation.
Elevation of conductivity during filling caused by:
- untreated residual water from pressure test or pre-rinsing
- metal salts (e.g. surface rust) dissolved out of the raw material
In cold water applications and warm humid ambient air can cause condensation in
the actuators. This can lead to corrosion in the gear box of the actuator and causes a
breakdown of it. In such applications, the use of a stem heating is provided.
The stem heating must be enabled only when the system is in operation, because it
does not have temperature control.
Ball valves, rotary actuators and sensors are maintenance-free.
8
Before any service work on the final controlling device is carried out, it is essential to
isolate the rotary actuator from the power supply (by unplugging the electrical cable
if necessary). Any pumps in the part of the piping system concerned must also be
switched off and the appropriate slide valves closed (allow all components to cool
down first if necessary and allways reduce the system pressure to ambient pressure
level).
The system must not be returned to service until the ball valve and the rotary actuator
have been correctly reassembled in accordance with the instructions and the pipeline
has been refilled by professionally trained personnel.

The direction of flow, specified by an arrow on the housing, is to be complied with,
since otherwise the flow rate will be measured incorrectly.
In order to achieve the specified measuring accuracy, a flow-calming section or inflow
section in the direction of the flow is to be provided upstream from the flow sensor. Its
dimensions should be at least 5x DN.
DN L min.
65 5 x 65 mm = 325 mm
80 5 x 80 mm = 400 mm
100 5 x 100 mm = 500 mm
125 5 x 125 mm = 625 mm
150 5 x 150 mm = 750 mm
L ≥
5 x DN
The valve is determined using the maximum required flow rate Vmax.
A calculation of the kvs value is not required.
Vmax = 30…100% of Vnom
If no hydraulic data are available, then the same valve DN can be selected as the heat
exchanger nominal diameter.
The minimum required differential pressure (pressure drop through the valve) for
achieving the desired volumetric flow max can be calculated with the aid of the
theoretical kvs value (see type overview) and the below-mentioned formula. The
calculated value is dependent on the required maximum volumetric flow max. Higher
differential pressures are compensated for automatically by the valve.

In case of a flow sensor error, the EPIV will switch from flow control to position
control. Once the error disappears, the EPIV will switch back to the normal
control setting.
