Description
The MVB actuator family offers a flexible and dependable solution for controlling globe valves in heating and cooling systems. Built around a synchronous reversing motor and intelligent electronic board, MVB actuators ensure smooth and stable valve movement, making them ideal for terminal units, hydronic circuits and standard HVAC applications.
Thanks to their versatile design, MVB actuators can be mounted not only on iSMA CONTROLLI valves but also on many third-party globe valves, making them a strong choice for both new installations and retrofit projects. The compact housing, manual override and easy electrical access simplify installation and servicing, while the quiet electromechanical motion ensures long-term operating comfort.
With a choice of floating, potentiometric or proportional control models, MVB adapts easily to any control strategy, providing a reliable actuator platform for commercial and residential HVAC environments.
