Description
The Johnson Controls D-4070-2 2-Stage Damper Actuator is a strong device that effectively regulates the airflow in HVAC systems. This actuator works at a pressure of 3 to 6 PSIG for the first stage and 11 to 14 PSIG for the second stage to effectively modulate the damper for the right environmental control. The actuator is mounted in ductwork systems and moves to the change in pressure signals to control the damper position and airflow rates. This dual-stage feature enhances the control accuracy and at the same time, provides a gradual transition to different environmental conditions
