I.                    Valbia

Introduction :

Valbia was built in 1995, in order to answer the requests of a more and more demanding market, that expects reliability, precision and constant innovation.
Our company relies on a very flexible dynamic structure and it is the only company in Italy to produce and sell all over the world single phase electric actuators, rack & pinion double acting and spring return pneumatic actuators, as well as special surface treated actuators to be used in extremely hard environmental conditions.
We offer a wide range of products able to satisfy every kind of demands and we offer as well the opportunity of customization according to the specific client's requests.

Valbia electric actuators are suitable for the automation of ball and butterfly valves for the industrial and construction sector. The usages of electronic components of last generation, together with precise mechanic, fruit of careful research and development, enables high performance and long-term reliability of the product.

Main Products:

Electric Actuator

Pneumatic Actuator

Automated valves

      OVERVIEW OF  ELECTRIC ACTUATOR :

Strong internal structure in die-cast aluminium

Self-extinguish techno polymer housing

Manual override

4 limit switches

Modulable version(standard /reverse)

Heating Resistor

Torque limiter

Double voltage/  voltage frequency

Advantages:

Heating  resistor  (standard  feature):  the  heater  is  activated,  with  the  powered actuator, when the motor is not working and the internal temperature drops below 25 ° C. This is a key feature in the event of wet or corrosive environment.!

Torque limiter: it interrupts the rotation in case of excessive load torque.!

Manual override and visual indicator: standard.!

4 limit switches: 2 standard & 2 auxiliary – no extra load (allow the user, for example, to connect emergency lights, alarms and other supply valves, ect.).!

Quiet  operation:  characteristic  obtained  using  the  first  gear  made  of  POM, incorporated in the gearbox close to the engine, when the torque is low.!

Double voltage: unlike most manufacturers, we offer power supply double voltage in each actuator, helping our distributors who may stock less options.!

Modulable ranges: the standard  setting is  4–20mA or  0–10V.  The reverse option 20–4mA 10–0V is programmable (except for the VB015).!

Model :

Standard : Series VB030- VB060 - VB110- VB190-  VB270 - VB350

·         6 models (from30 to 350Nm).

·         Power supply 12V ac / dc or 24V ac / dc or 100–240V ac, 50–60Hz

·         Option low/high voltage.

·         Self-extinguish techno-polymer housing, potected in conformity with IP67 (EN60529)

·         Temperature limits: -20° C +55° C

·         Standard rotation 0° -90° (optional 0 ° -180 ° – 0 ° -270 °).

·         The connection part of the actuators with the valves, is made by die-casted and painted alluminium plate cataphoresis, with a dua drilling interface as per ISO 5211.

·         In case of loss of power, the actuator keep the position

·         2 or 3 points control mode.

·         Duty rating 75% => (Working time/Working time + rest time) – for ex. VB060 bassa tensione, WT=9sec. Vs RT=3sec

VB015

·         Power supply 12V ac / dc or 24V ac / dc or 100–240V ac, 50–60Hz.

·         Heating resistance standard.

·         Housing protection in accordance with IP65 (EN60529).

·         Standard version on/off – 0° / 90°.

·         Also available in 0° / 180° version.

Customize products:

Version with positioner:

Standard version features:

•  The range can be set between 45 ÷ 320°.!

•  Control (0–10V) or voltage (4–20mA) command.!

•  CMD OUT connector with voltage or current feedback!

•  No extra-setting required.!

•  Resolution of 1.3 ° control, positioning tolerance <3% full scale potentiometer.

•  Modes of Operation "standard" 4mA (0V) closes, 20mA (10V) opens or "reverse" 4mA (0V) opens, 20mA (10V) closes. A yellow flashing LED indicates which operation mode is active.

Version with Battery Backup:

•  Technical features as per the standard version.

•  In case of power supply lack, the battery is running one of the following functions: open, close, ending the operation (standard) or open/close (with pos.).

•  Battery operation is immediately enabled, as soon as the voltage supply is interrupted, and it is stopped by the reactivation of the supply voltage.

•  Automatic rechargeable system when the actuator is power supplied.

•  The battery charge state is monitored by the power supply board and displayed using the appropriate red LED.
