Siemens 331-2794 Damper Actuator Pneumatic No.6 3-13 PSI

This Siemens 331-2794 Damper Actuator Pneumatic No.6 is a reliable part which is used to control HVAC systems. Utilizing this pneumatic actuator, damper positions can be precisely modulated resulting in optimal airflow and temperature regulation in this system. It works within a spring range of 3 to 13 PSI, giving enough variation to fit with numerous pressure settings according to the needs of the system. The actuator moves damper blades end of the 4 in stroke which effectively counteracts gas distribution within ductwork. A 1/8" NPT connection provides a reliable and leak proof attachment to pneumatic lines throughout the actuator's life.
