Description
The Daikin-McQuay 300034402 Normally Opened Actuator 277V is an electromechanical part that operates valve or damper positions based on electrical input signals. It remains in an open state under normal conditions and shifts position when energized to regulate flow or air passage within connected equipment. In HVAC systems, it is used to control airflow or fluid movement in heating and cooling circuits, supporting coordinated system operation and response to control commands. It is commonly applied in commercial installations where automated regulation of air or water distribution is required for stable and efficient system performance.
