Description
The Honeywell MP913A1177 Pneumatic Variable Volume Damper Actuator is a control component used in the damper blade position in reaction to a 313 PSI control signal in HVAC systems. It is used in air handlers, VAV boxes, and ventilation units to change the pressure feeding the system to mechanical movement that regulates the volume of airflow via ductwork. It is mounted on the damper shaft or linkage and is connected with the control network of the building in order to allow the proportional adjustment of airflow to balance the zones and assist in keeping the condition desired.
