The Johnson Controls D-3153-5 Damper Actuator; 8-13# Spring 4″DIA Bracket 3″ STROKE 105# Power STRK

Datasheet

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).

When used with proportional control, the damper size is limited to 16 ft2 (1.5 m2) maximum. As a 2-position control, damper size is limited to 25 ft2 (2.3 m2).

Three nominal spring ranges are available:

• 3 to 7 psi (21 to 49 kPa), D-3153-7
• 5 to 10 psi (35 to 70 kPa), D-3153-3 and -6
• 8 to 13 psi (56 to 91 kPa), D-3153-1, -2, -4, -5, and -18

The control air pressure for normal HVAC operation is 0-20 psig (0-138 kPa). The minimum control pressure for safety damper functions is 20 psig (138 kPa) with the maximum pressure of 30 psig (207 kPa). When used for both proportional and safety applications, provide a separate air signal to override normal HVAC operation and cause safety damper functions.

The D-3153 Pneumatic Actuator incorporates several internal and external features that add functional flexibility. A 2-way swivel connection on the actuator cylinder head provides non-binding movement.
