VA9208-AGx-x Series On/Off and Floating Point Electric Spring Return Valve Actuators
Installation Instructions 1
Refer to the QuickLIT website for the most up-to-date version of this document.
Applications
The VA9208-AGx-x Series On/Off and Floating Point
Electric Spring Return Actuators are direct-mount valve
actuators that operate on AC/DC 24 V power. These
bidirectional actuators are used to provide accurate
positioning on Johnson Controls® VG1000 Series
1-1/4, 1-1/2, and 2 in. (DN32, DN40, and DN50) ball
valves in Heating, Ventilating, and Air Conditioning
(HVAC) applications.
Integral line voltage auxiliary switches, available only
on the VA9208-xxC-3 models, indicate end-stop
position, or perform switching functions within the
selected rotation range.
VA9208-AGA-2 actuators include plenum-rated cables
and are specially configured for installation in spaces
used for environmental air-handling purposes other
than ducts and plenums as specified in National Fire
Protection Association (NFPA) 70: National Electrical
Code section 300.22(C), Other Space Used for
Environmental Air. The space over a hung ceiling used
for environmental air handling purposes is an example
of the type of space for which these actuators are
configured.
Installation
Install the ball valve with the actuator at or above the
center line of the horizontal piping (see Figure 1).
IMPORTANT: Use this VA9208-AGx-x Series
On/Off and Floating Point Electric Spring Return
Actuator only to control equipment under normal
operating conditions. Where failure or malfunction of
the electric actuator could lead to personal injury or
property damage to the controlled equipment or
other property, additional precautions must be
designed into the control system. Incorporate and
maintain other devices, such as supervisory or
alarm systems or safety or limit controls, intended to
warn of or protect against failure or malfunction of
the electric actuator.
IMPORTANT : Utiliser ce VA9208-AGx-x Series
On/Off and Floating Point Electric Spring Return
Actuator uniquement pour commander des
équipements dans des conditions normales de
fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du electric actuator risque de
provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la
conception du système de contrôle doit intégrer des
dispositifs de protection supplémentaires. Veiller
dans ce cas à intégrer de façon permanente
d'autres dispositifs, tels que des systèmes de
supervision ou d'alarme, ou des dispositifs de
sécurité ou de limitation, ayant une fonction
d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du electric
actuator.
IMPORTANT: In steam applications, install the
valve with the stem horizontal to the piping. Failure
to follow this precaution may shorten the life of the
actuator.

IMPORTANT: Before specifying VA9208 Series
Electric Spring Return Valve Actuators for plenum
applications, verify acceptance of exposed plastic
materials in plenum areas with the local building
authority. Building codes for plenum requirements
vary by location. Some local building authorities
accept compliance to UL 1995, Heating and Cooling
Equipment, while others use different acceptance
criteria.

IMPORTANT: Do not install or use this VA9208
Series Electric Spring Return Valve Actuator in or
near environments where corrosive substances or
vapors could be present. Exposure of the actuator to
corrosive environments may damage the device’s
internal components, and will void the warranty.

adjustable pointer into place.
Mounting the Thermal Barrier
Figure 16 shows the optional M9000-561 Thermal
Barrier.
To mount the optional thermal barrier:
1. Install the thermal barrier drive shaft into the
thermal barrier by aligning the tab on the drive
shaft with the slot on the thermal barrier
(Figure 17).
2. Rotate the drive shaft to align marks on the top of
the thermal drive shaft with matching marks on the
valve stem.

3. Mount the thermal barrier onto the valve using the
four included M5x16 mm machine screws and four
M5 flange nuts. Tighten the screws to a
recommended torque of 21 to 25 lb·in.
(2.4 to 2.8 N·m) (Figure 18)
4. Proceed to the actuator mounting instructions.
Follow the same steps as mounting directly to the
valve when mounting actuator to the thermal
barrier.
Note: Depending on your application, you may
position the assembly in any of the four 90° increments
on the valve.
Manual Override
Use only the supplied manual override crank to
reposition the actuator hub when using the manual
override feature.
To reposition the actuator hub, proceed as follows:
1. De-energize the actuator.
2. Insert the hex end of the manual override crank
into the manual override adjustment point on the
face of the actuator.
3. Rotate the manual override crank in the direction
indicated by the arrow on the label.
4. The actuator requires 8-1/2 manual override crank
rotations from the full spring return position to fully
reposition the actuator hub. At the end of travel, the
rotation resistance increases. Do not force the
manual crank past this point.
5. While holding the manual crank in the wound
position, rotate and hold the red lock shaft
approximately 10° then release the manual crank
to lock the actuator hub in place.
Note: Insert and slightly rotate the manual crank
in the direction indicated by the arrow on the label
to unlock the actuator hub. Alternately, the actuator
hub automatically unlocks when power is applied
to the actuator, and returns the actuator to normal
drive and spring return operation.
Wiring
IMPORTANT: Applying excessive torque to the
manual override or operating the manual override
with a power tool may damage the internal
components of the actuator and cause premature
failure.

WARNING: Risk of Electric Shock.
Disconnect or isolate all power supplies
before making electrical connections.
More than one disconnection or isolation
may be required to completely
de-energize equipment. Contact with
components carrying hazardous voltage
can cause electric shock and may result
in severe personal injury or death.
AVERTISSEMENT : Risque de
décharge électrique.
Débrancher ou isoler toute alimentation
avant de réaliser un raccordement
électrique. Plusieurs isolations et
débranchements sont peut-être
nécessaires pour -couper entièrement
l'alimentation de l'équipement. Tout
contact avec des composants porteurs
de tensions dangereuses risque
d'entraîner une décharge électrique et de
provoquer des blessures graves, voire
mortelles.

CAUTION: Risk of Property Damage.
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte
risquent d'endommager
irrémédiablement l'équipement.
!
CAUTION: Risk of Property Damage.
Insulate and secure each unused wire
lead before applying power to the
actuator. Failure to insulate and secure
each unused wire lead may result in
property damage.
MISE EN GARDE : Risque de dégâts
matériels.
Isoler et protéger chaque fil non utilisé
avant de mettre l'actuator sous tension.
Le non-respect de cette obligation
d'isolation et de protection de chaque fil
non utilisé risque d'entraîner des dégâts
matériels.
IMPORTANT: Make all wiring connections in
accordance with the National Electrical Code and
local regulations. Use proper Electrostatic Discharge
(ESD) precautions during installation and servicing
to avoid damaging the electronic circuits of the
actuator.
IMPORTANT: Multiple VA9208-AGx-x Actuators
must be on independent loads.
