1.0 Warning
• Please read the following instructions before making any installation of the actuator. The damages caused from the non-observance of these instructions
are not covered in the warranty.
• This documentation must be kept in dry place and available for use.
• The actuator is an electronic device and during its working operations some parts are live components. The installation and maintenance of electric
actuator must be made only by qualified personnel, in accordance with current electrical engineering and safety standards and all other applicable
directives.
• Valbia s.r.l. reserves the right to change the data and the characteristics of this manual at any time and with no notice in the scope of a constant updating
and technological improvement.
WARNING: the mechanical and electronic parts, according to which the device is designed, are not eligible for modifications.
2.0 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.
3.0 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.
4.0 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.

Page 2: Specifications And Technical Information
Use copper (CU) conductor 5.1 Technical features Technical characteristics of Valbia electric actuators as below: • Heater: all actuators are standard equipped with heater to avoid condensation into the actuator (paragraph 6.4); • a safety system detects when the actuator supplies a torque higher than expected (torque limiter): the device makes three triggering attempts. In case of negative results, it makes a short rotation in the opposite direction to relieve the mechanical tension to the gears. -

WARNING: make sure that the power supply is set between the values indicated as indicated on the label on the side of the actuator. WARNING: Valbia electric actuators may be mounted in many positions, however, we do not suggest using it with the cable glands positioned upright, since it cannot guarantee a perfect wiring tightness. -
