Q
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.
■ Observe the direction arrow on the valve body. Inverting the direction of flow impairs control
behavior.

Mounting and commissioning the actuator
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-HE, MD15-R-HE 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.
► After the line power has been 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 actuator will not respond to the control signal until the initialization run is complete.

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 removing the actuator.
CAUTION
!
Before beginning to remove the unit, move the actuator to the uppermost position.

Manual adjustment
CAUTION
!
!
Manual adjustment may only be performed when the actuator is installed.
► Disconnect the actuator from the power supply.
► Fold the cover nipple to the side.
► A hexagon key (key socket 4 mm) can be used to move the actuator
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.
This occurs during operation when a valve end position is reached as part of normal operation.
You can perform this initialization manually by activating switch 6; see p. 13.

Switch 1: Valve exercise
If plant specifications permit, the valve exercise feature may be activated during commissioning.
Valve exercise prevents the cone from jamming when the valve is not
moved for a long period of inactivity, e.g. for heating systems during the
summer.
If valve exercise is activated, the valve cone is raised for a few seconds
when there is no movement for 21 days.

Switch 6: Reinitialization
When the unit is remounted, you must adapt the valves again by performing a reinitialization.
You can do this by moving switch 6 from “OFF” to “ON” or from “ON” to
“OFF”.
The LED (under the connection cover) flashes during initialization.
