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 has been 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 Applications
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 Actuator Mounting
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. Do not grab the actuator by the manual hand-wheel.

TERMINAL BLOCK "G" TERMINAL BLOCK “R” Fig.4 Control/logic board and particular of terminal blocks “G” and “R” 6.3 Heater (Fig.5) All the actuators are equipped with “RIS” heating resistor which works only if the actuator is connected to the power supply, when the motor is not rotating and the temperature inside the actuator goes down to 25°C / 77°F. - Page 6 2. “Reverse” mode: 20 mA (closed) ÷ 4 mA (open) or 10V (closed) ÷ 0V (open). The “Standard” mode is the default condition. This setting between the operating modes is done using the buttons on the control PCB card: • to enter the programming mode hold down the “M” button for 5 seconds; •...
