Installing the unit
Mount the unit on a ball valve, butterfly
valve or ball valve combination
Valves supplied by the manufacturer
have a drive coupling that fits the actua-
tor. For other valves, the connection must
comply with the requirements of
DIN EN ISO 5211, and the actuator must
be equipped with a suitable adapter.
For more information about available
and possible valves, please contact
the manufacturer.
Valves must be correctly mounted.
When you install the actuator on a valve,
ensure that the position of the ball / but-
terfly valve or similar device and the
position of the actuator agree. When the
valve is open, the notch in the actuator
drive shaft must be in the 90° or 270°
position (or 0° or 180° if mounted trans-
versely) (there are degree markings on
the cover of the actuator).
Regarding the position indicator of an
actuator for installation on a multi-way
valve or a valve combination, please
contact the manufacturer.
The connection between the actuator and
the valve should be either direct or by
means of a special actuator connection.
There must always be a drive coupling
on a valve. The mountings for an actua-
tor and an actuator coupling on a valve
are not always identical.
The number of mounting screws depends
on the actuator type. This section shows
the actuator mounted on a multi-way
valve.
The type of mounting on your unit is
shown on the drawings supplied.
Please contact the manufacturer if you
need more information about mount-
ing the actuator.
