What device is typically used to position dampers and control valves?

The device commonly used to position dampers and control valves is an actuator. Actuators convert control signals into mechanical motion, allowing them to adjust the position of dampers or valves to regulate the flow of air, steam, or fluids within a system. They can be powered by different sources, such as electricity, hydraulic fluid, or pneumatic pressure, and are essential for automated control systems where precise positioning is crucial for maintaining the desired operating conditions.

Actuators play a significant role in heating, ventilation, air conditioning (HVAC) systems and industrial processes, helping enhance efficiency and ensure safety by maintaining proper flow rates and pressures. This functionality sets actuators apart as the primary choice for the task of positioning dampers and control valves.
