Siemens Building Technology GVD126.1U 2-Position Fire & Smoke Damper Actuator S/R 200 lb-in 24V

The Siemens Building Technology GVD126.1U Fire & Smoke Damper Actuator is a part that controls the airflow of fire and smoke dampers in HVAC systems. It has a 2-position control signal and a spring return mechanism that returns the damper to a safe position in the event of power supply failure. The actuator is activated by a 24V signal to open or close the damper depending on the need of the system. In case of power failure the spring return operation of the damper ensures that it returns to the fail-safe position. This actuator is most suitable for installation in commercial HVAC systems to improve fire safety standards, reduce smoke penetration and increase the efficiency of the system.
