VA9204-Bxx-2 Series On/Off Electric Spring Return Valve
Actuators
Installation Guide
Applications
VA9204-Bxx-2 Series on/off electric spring return actuators
are direct-mount valve actuators that operate on 24 VAC
power at 50/60 Hz, 24 VDC power, or 85 VAC to 264 VAC
power at 50/60 Hz. These bidirectional actuators are used for
on/off control on Johnson Controls® VG1000 Series 1/2 in.,
3/4 in., and 1 in. (DN15, DN20, and DN25) ball valves in
HVAC applications.
An integral line voltage auxiliary switch, available only on
the VA9204-xxB-2 models, indicates end-stop position, or
performs switching functions within the selected rotation
range.
IMPORTANT: Use this VA9204 Series valve actuator only
to control equipment under normal operating conditions.
Where failure or malfunction of the VA9204 Series
valve 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 VA9204 Series valve actuator.
IMPORTANT : Utiliser ce VA9204 Series valve actuator
uniquement pour commander des équipements dans
des conditions normales de fonctionnement. Lorsqu'une
défaillance ou un dysfonctionnement du VA9204 Series
valve 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 VA9204 Series
valve 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.

condensing atmosphere applications
IMPORTANT: Do not install or use this VA9204 Series
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.
Special tools needed
• Digital voltmeter
• T-20 TORX® driver
