Siemens GQD151.1P Spring Return Rotary Electric Damper Actuator 20 lb-in 24V 2-10VDC

The Siemens GQD151.1P Spring Return Rotary Electric Damper Actuator controls HVAC airflow precisely. The actuator generates 20 in-lb torque while running at 24 volts using its 2-10VDC control signal to position itself accurately. This actuator handles airflow control in air dampers and ventilation systems plus VAV units to achieve optimal performance. When power fails, the spring-return function moves the damper back to its original position automatically. Its small size fits well in tight areas to strengthen system stability and operation. This makes HVAC systems perform better by using less energy while keeping air and temperatures steady.
