Product Overview

2 D-3153 Pneumatic Actuator Product Bulletin
A
pplication
When used with proportional control, the damper size
is limited to 16 square feet maximum. As a 2-position
control, damper size is limited to 25 square feet.
Three nominal spring ranges are available:
3-7 psi (D-3153-7), 5-10 psi (D-3153-3 and -6),
and 8-13 psi (D-3153-1, 2, 4, 5, and 18). The control
air pressure for normal HVAC operation is 0-20 psig.
The minimum control pressure for safety damper
functions is 20 psig with the maximum pressure of
30 psig. When used for both proportional and safety
applications, a separate air signal should be provided
to override normal HVAC operation and cause safety
damper functions.
The D-3153 incorporates several internal and external
features that add functional flexibility. A 2-way swivel
connection on the actuator cylinder head provides
non-binding movement. All actuators have a
telescoping piston rod for easy linkage of the damper
for attachment points up to 8-3/4 inches (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 component recognized D-3153 actuator with
universal and auxiliary mounting brackets are
specifically designed for use with Johnson Controls
safety dampers up to 250°F (121°C).
O
peration
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 will move to a
position where the applied force and the spring plus
external forces are in equilibrium. However, with a
pilot positioner added, the piston will move to a position
proportional to the control signal regardless of the load.
I
nstallation
Two standard mounting packages are available with
the D-3153 pneumatic piston 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 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 foot (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, a D-9502
positioner should be used. Up to four more D-3153
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 D-9502 literature).
Refer to the appropriate
D-3153 Installation Bulletin for
