 The cable of the actuator must be installed in a fixed position
and protected against mechanical damage.
 For installation, use and maintenance the official standards
and rules must be applied.
3) With horizontal installation position of the actuator, the
two spacer rods must form a vertical level.
 Temperature class T6 is only for the actuator, you have to
guarantee max. temperature of valves and tubes on site.
 The EEx actuators may only be opened by the
manufacturer to guarantee explosionproof and for
warranty.
 For outdoor installation a heater and a weather protective
housing against rain, snow and sun is required.
 After installation all componetes must fulfil the protection class
IP65 acc. EN60529.

Mounting instructions for the
valve body to the actuator EXV-...
1. The actuator will be delivered
with retracted stroke.
2. Place the actuator on the
valve body and attach with
the nuts and washers (1) provided.
3. Remove the cap nut (2) and
screw the connecting parts with
the connecting nut (3), taking
care not to damage the valve spindel.
The spindle should be retracted as
far as possible into the valve body.
4. Allow enough distance between
the threaded bolt head (4) and the
rod of the actuator, noting the travel
of the valve spindle. Any adjustment
can be done by screwing the bolt (4)
into the connection nut(3).
Tighten both counter nuts firmly.
5. Draw out the valve spindel with the
connecting parts until contact is
made to the threaded actuator rod
and join with the cap nut (2).
Do not overthighten (max. 4 m)
otherwise damage will be cause to
the mounting bracket.
6. onnect the actuator to the
supply in accordance with the
enclosed wiring diagram.
7. Operate the actuator electrically to
fully extend the actuators rod.
For modulated controlled actuator
with a 20 mA or 10 VD positioning
signal or by connecting to load via
terminal 4 (if no positioning signal available).
Visual check that the valve is closed.
Minor adjustment to the travel can be
achieved by turning the threaded bolt (4).
8. Secure all connections, take care not to
operate the actuator against the
stroke otherwise damage to
mounting bracket may occure.
9. The actuator is ready to operate.
Montage Ventilkörper an Antrieb EXV...
1. Der Antrieb wird werkseitig mit
eingefahrener Hubstange ausgeliefert!
2. Den Antrieb auf den Ventilkörper
stecken und mittels der mitgelieferten
Muttern (1) befestigen.
3. Überwurfmutter (2) lösen und
Verbindungsteile mittels der
Verbindungsmutter (3) locker auf
die Ventilspindel schrauben.
Ventilspindel dabei ganz hineindrücken!
4. Zwischen dem Schraubenkopf von
Schraube (4) und der Hubstange des
Antriebes entsprechend dem Ventilhub
Platz lassen, Ventilhub vorher messen und
notieren. Justage erfolgt über Schraube (4)
bzw. Verbindungsmutter (3).
5. Die beiden Kontermuttern (5)
handfest anziehen.
Die Ventilspindel mit den
Verbindungsteilen herausziehen und
mit Hilfe der Überwurfmutter (2) auf
der Hubstange befestigen.
icht zu fest anziehen (max. 4 m -
Zerstörung der internen Verdrehsicherung!)
6. Antrieb elektrisch nach dem Antrieb
beiliegenden Anschlußschema anschließen.
7. Antrieb elektrisch ausfahren lassen.
Bei Stetig-Antrieben mit Signal 20 mA bzw.
10 VD oder durch Auflegen der
Betriebsspannung auf Klemme 4 falls
noch kein Stellsignal vorhanden ist.
Funktion überprüfen - schließt Ventil?
Eine Nachjustage ist mittels Schraube (4) möglich.
8. Alle Verbindungen fest anziehen, dabei
darauf achten, daß nicht gegen die
Hubstange gekontert wird - Zerstörung der
internen Verdrehsicherung.
9. Der Antrieb ist betriebsbereit.
