Siemens 331-4812 Pneumatic Damper Pivot Actuator, 3 8-13PSI Pivot Actuator

The Siemens 331-4812 Pneumatic Damper Pivot Actuator is a well-fabricated component that is used in the management of the damper in HVAC systems. This actuator has a stroke length of 2 3/8 inches which allows the damper positions to be adjusted to regulate the airflow appropriately. Incorporating a pneumatic mechanism for the damper, the Siemens 331-4812 uses air pressure to operate the pivot of the device. During spring it varies between 8 and 13 PSI this ensures the actuator of the ability to handle the pressure required in operating the dampers.
