Product Overview

D-3153 Pneumatic Actuator Product Bulletin2
All actuators have a telescoping piston rod for easy
linkage of the damper for attachment points up to
8-3/4 in. (222 mm) away from the face of the actuator.
A swivel ball joint and slotted crank arm connector are
furnished on all actuators for optional methods of
linkage to the damper.
The UL recognized component D-3153 Pneumatic
Actuators, with universal and auxiliary mounting
brackets, are specifically designed for use with
Johnson Controls® safety dampers up to 250°F
(121°C).
Operation
Air pressure from a pneumatic controller is applied to
the diaphragm of the actuator, which moves the piston
against the forces of the internal spring and the load.
The external load force shifts the operating range from
the nominal spring range. The piston moves to a
position where the applied force and the spring, plus
external forces, are in equilibrium. However, with a pilot
positioner added, the piston moves to a position
proportional to the control signal regardless of the load.
Installation
Two standard mounting packages are available with
the D-3153 Pneumatic Actuator. The models with
universal mounting bracket assemblies provide all of
the parts and instructions required for applying the
actuator to Johnson Controls D-1300 damper
applications: duct (wall) mounting or frame mounting,
either normally open or normally closed.
The auxiliary mounting bracket assembly facilitates
applying the D-3153 Pneumatic Actuator to allied
equipment manufacturer's products, and non
Johnson Controls installations for actuator
conversions. These assemblies are furnished with a
crank arm linkage and pedestal style bracket. Two
positions are provided on the pivot post for attaching
the actuator to the mounting bracket so that force can
be more directly applied to linkage points that are
neither perpendicular nor parallel to the actuator
mounting plane.
A stop screw kit is available for special applications to
limit the power stroke of the actuator when required. A
4 ft (122 cm) linkage rod is also available for special
applications to reach extended linkage when required.
Where precision sequential operation is desired, or
additional positioning power is necessary, use a
D-9502 positioner. Up to four more D-3153 Pneumatic
Actuators may be slaved from one pilot for coupled
dampers. A D-9502 kit is also available to enable 2-
stage actuator control for providing minimum outdoor
air during occupation (refer to the D-9502 Pneumatic
Damper Actuator Positioner Product Bulletin [LIT-
1628399P]).
Refer to the D-3153 with Universal Mounting Bracket
Installation Bulletin (Part No. 34-188-18) and the
D-3153 with Auxiliary Mounting Bracket Installation
Bulletin (Part No. 34-154-19) for more details.
Repair Information
Do not make field repairs. If the D-3153 Pneumatic
Actuator fails to operate within its specifications,
replace the unit. For a replacement actuator, contact
the nearest Johnson Controls representative.
