Installation Instructions
VA9208-AGA-3, VA9208-AGC-3
VA9208-AGA-2
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.

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.
Installation
Install the ball valve with the actuator at or above the
center line of the horizontal piping (see Figure 1).
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.
