Valve actuators
Optimal integration thanks to a wide product range
In order to optimally meet project-specific requirements, Belimo also offers a wide range of actuators in addition to the wide valve product range. This ensures optimal integration into the building management system and the best possible water-side control in all HVAC applications.
The use of actuators with durable brushless DC motors combined with specially designed gears and the patented motor control ensures safe and energy-saving operation of the valves. Thanks to sophisticated retrofit solutions, the valves can also come from third-party manufacturers in existing buildings.
