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.

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 6.3); • a safety system detects when the actuator supplies a torque higher than expected (torque limiter). In this case the safety system blocks the actuator. The torque limiter intervention is indicated by a red color LED (paragraph 6.4) and by the opening of the remote signal an auxiliary contact (paragraph 6.2);... -

Questions and answers
How do I turn the water back on after the device turns it off
To turn the water back on for the VaLBIa 85 Series device, make sure the actuator moves the valve to the “OPEN” position. You can do this by:
1. Ensuring the power supply is on and the actuator is powered.
2. Using the OPEN button to move the valve to the open position.
3. If needed, manually override the actuator to set the valve to “OPEN” (refer to manual override in paragraph 7.0).
This will allow water to flow through the valve.
