Warnings
•
Please read the following instructions before making any instal-
lation of the actuator. The damages caused from the non-ob-
servance of these instructions are not covered in the warranty.
•
This documentation must be kept in dry place and available for
use.
•
The installation and maintenance of electric actuator must be
made only by qualified personnel.
•
Before proceeding to the electrical connections, please make
sure the ground wiring system works correctly.
•
Please always check that supply voltage is included between
the ones indicated on the label on the exterior of the actuator.
•
Before making any maintenance on the actuator, always make
sure to shut off the power supply.
•
Valbia s.r.l. reserves the right to change the data and the char-
acteristics of this manual at any time and with no notice in the
scope of a constant updating of technological improvement.
WARNING: The mechanical and electronic parts, according to
which the device is designed, are not eligible for modifications.
2.
Transportation and storage
Valbia electric actuators are supplied in paperboard boxes which are
of solid construction for a normal transport. Handle with care and
keep the cover until the moment of the installation of the actuator
The storage of the actuators requires a covered, dry and ventilated
environment, protected from temperature changes. The device must
be stored with the cover mounted. Prior to installation, visual
inspection is recommended to detect any anomalies caused by
transport or storage.
WARNING: Do not lift or move the actuator by the manual hand
wheel
3. Field application
VALBIA electric actuators have been designed and tested to ball and
butterfly valves and dampers for the industrial sector. Actuators are
available in standard version with rotation 0°-90°. On request we can
supply actuators with rotation 0°-180° or 0°-270°. For applications
other than that above are needed please contact VALBIA sales
department.
4. Valve automation
The mechanical assembling between the electric actuator and the
item to be automated (for example: the valve) can be done by
direct mounting or by a mounting kit. Both the cases you can verify
the right alignment and the correct dimensions of the part to
transmit the power in order to avoid axial stress which can damage
valve and actuator.
All Valbia electric actuators are in conformity of norm EN ISO 5211
DIN 3337.
In order to have a right automation of the valve, is necessary to use
a Valbia electric actuators whose range has a torque of at least
25% over the valve maximum torque.
Verify the actuator duty rating suitability with the application.
WARNING: Do not raise up or moved the motorized valve by using
the electric actuator as point of grip or hold.
