The range has been manufactured with the following characteristics:
The housing of the actuators provides a V0 self-extinguish class techno-polymer material.
The kinematics is made by two steel and techno-polymer gear wheels, sustained by hardened steel pinions, mounted on self-lubricating bushes (excluding Model VB015), and inserted into a strong structure of die cast aluminium.
The connection part of the actuators with the valves is made by die casted and painted aluminium plate cataphoresis, with dual drilling interface as per the ISO5211 - DIN3337 standard
The electronic circuit adjusts automatically the motor speed depending on the mechanical charge variations in order to drive the cycle always in the same time
All actuators are provided with an electronic system for torqu limitier
A heating resistance is activated, by powered actuator, once the temperature inside the housing drops below 25DegC (except for model VB015) and the motor is not running.

All actuators except VB015 can be fitted with:
Modulating Service 4-20mA or 0-10V.
Linear Potiometer
Equiped with Battery back-up for emergency control
