Damper Actuator; 8-13#Spring W/2 STAGE POS
The D-3153 Pneumatic Actuator is a multipurpose positioning device used primarily for operating ventilating dampers in response to the output signals of a pneumatic controller or electro-pneumatic transducer.
The D-3153 Pneumatic Actuator is used with dampers up to a maximum area of 16 ft2 (1.5 m2) for proportional volume control, and 25 ft2 (2.3 m2) for 2-position actuation (provided that the torque requirements are compatible with the specific application).
