Kvs default setting for R10 - 20DV/EV valves
To adjust to the heat requirement, the R10 - 20DV/EV valves have 8 flow settings for the radiator
mass flow rate.
The maximum flow rate, Kvs value (m³/h) can be selected by using the settings 1, 2, 3, 4, 5, 6, 7 or
8 (delivery setting = 8, corresponds to a Kvs value = 0.86).
The setting can be made using a Z29 socket key (accessory). The setting between 1 and 8 can be
read from the valve, and will be implemented by the installed small actuator.

Q
Valve Installation
!
CAUTION
The valve may only be installed by qualified technicians. In addition to the generally applicable installation guidelines, the following items are to be observed:
■ The pipeline system and the fixture interior must be free of foreign objects. In the event of contam-
inated media, dirt collectors are to be inserted upstream of the valves with fine screens, mesh width
0.25 mm.
■ There must be no tension between the valve and the pipeline connection.
■ To avoid eddy formations in the valve body, the valve should be installed in a straight section of the
pipe. A distance of 10 times the nominal diameter is recommended between the valve flange and
manifold or other similar parts.
■ The installation location is to be selected so that the ambient temperature at the actuator is kept
between 0 °C–+50°C.
■ When carrying out installation, the permissible max. pressure difference p and the specified
direction of flow must be observed (see table in "Types" section, as well as the "Valve Principle").
■ The three-way valves are to be used as mixing valves. Pay attention to the direction of flow (see
fig. "Valve Principle").
■ Once the valve is installed, make sure the ball in the valve seating can be moved easily by pushing
in the valve stem.
■ To install the actuator and remove the housing cover, approx. 170 mm of free space is required
above the actuator.
■ For safety reasons, do not suspend the small actuators under the valve.
■ Observe the direction arrow on the valve body. Inverting the direction of flow impairs control
behavior.

Q
Mounting and Commissioning the Actuator
WARNING
Contact with live parts of electrical domestic installation can cause death due to electric shock.
Mounting/removal may only be carried out when power is switched off.
CAUTION
Installation and commissioning work may only be carried out by qualified technicians.
If the valve is installed in the system, make sure that no differential pressure builds up in the valve
body before beginning work. If necessary, close the gate valve and turn off pumps. After the pipeline
has cooled off, the actuator can be installed.
Be sure to comply with VDE guidelines and local wiring regulations. The device is connected
according to the legally binding system circuit diagram.
!
CAUTION
Do not operate the MD15/230-HR, MD15/230-HE, MD15/230-DA Small Actuator electrically
without a valve.

► Place the actuator on the threaded connection of the valve and tighten hand-tight using the union
nut.
► Establish the electrical connection.
► The first time the line power is switched on, an automatic initialization run takes place. The
actuator first travels to the upper end position and then to the lower end position. The valve is now
adapted.
The actuator will not respond to the control signal until the initialization run is complete.
!
CAUTION
After recommissioning or a manual adjustment, an initialization run must be triggered manually. This
is done by flipping the DIP switch before switching on the power supply (see Fig. 6).

Q
Dismounting the Actuator
CAUTION
Before beginning to remove the unit, make sure that no differential pressure builds up in the valve
body before beginning work. If necessary, close the gate valve and turn off pumps.
After the pipeline has cooled off, you can begin removal of the small actuator.
Dismounting: M15/230-HR and MD15/230-HE
► Move the actuator to the center position using a control signal.
► Disconnect the small actuator from the mains power supply. Then disconnect all electrical
connections.
► Remove the union nut.
► Remove the small actuator from the valve.

Manual adjustment
!
CAUTION
Manual adjustment may only be performed when the actuator is installed.
■ The small actuator must be disconnected from the mains power supply
for manual operation.
■ Using a hexagon key (key socket 4 mm), the actuator can be moved
into any position.
!
CAUTION
If you manually adjust until the slip clutch responds, turn the hexagon key half a turn in the opposite
direction after the manually set stroke position has been reached.
NOTE
An initialization run must be performed after a manual adjustment, see Reinitialization section on p.14

Q
Initialization and adjustment to the valve stroke
WARNING
Contact with live components of the building’s electrical system can cause death due to electric
shock.
The actuator must be disconnected from the power supply before you remove the terminal cover and
flip the switch.
Reinitialization
The valve stroke must be reinitialized whenever the unit is remounted
or adjusted manually.
► Disconnect the actuator from the power supply and remove the
terminal cover.
► Change the switch position (1).
► Replace the terminal cover and reconnect the power supply.
The actuator will perform an initialization run.
NOTE
A valve stroke initialization is also performed when a valve end position is reached during normal
operation.
