The Actuator housing is made from 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 bushings (excluding Mod. VB015), and inserted in a rugged die-cast aluminum structure.

The direct connection part of the actuators to the valves, is made via a painted die-cast aluminum plate, with a dual drill ISO5211 interface.

The electronic circuit automatically adjusts the motor speed, (depending on the mechanical charge variations), to keep the cycle time consistent.

All actuators are provided with an electronic system and torque limiter.

A standard furnished heater is activated once the actuator is powered, and when the temperature inside the housing drops below 77°F.

Two auxiliary limit switches are standard.

Manual Override & Visual position indicator, standard.

Optional 4-20 milliamp 0-10 v modulating boards and battery back-up protection are available.
