Siemens 331-4310 Damper Actuator, Pneumatic, Number 3 3-7PSI, 2 3/8" Stroke

The Siemens 331-4310 Pneumatic Damper Actuator that is used in HVAC systems in order to control flow rate and temperature. This actuator has a stroke length of 2-3/8” and it is designed with high efficiency for use in different areas. It operates through the use of pneumatic pressure in the spring range of 3-7 PSI to move its parts. With this pneumatic actuator, it is possible to set the dampers at any location since with compressed air, one can push or pull them with a lot of precision.
