Applications
The VA9208-Bxx-x Series On/Off Electric Spring
Return Actuators are direct-mount valve actuators that
operate on AC 24 V power at 50/60 Hz, DC 24 V
power, AC 120 V power at 60 Hz, or AC 230 V power at
50/60 Hz. These bidirectional actuators are used to
provide two position control 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.
The VA9208 Series Electric Spring Return Actuators
provide a running torque of 70 lb·in. (8 N·m). 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.
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-Bxx-x Series On/
Off 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-Bxx-x Series On/
Off 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.
