VA9203-xxx-xx Series Electric Spring Return Valve Actuators Product Bulletin 1
Refer to the QuickLIT Web site for the most up-to-date version of this document.
The VA9203-xxx-xx Series Electric Spring Return
Valve Actuators are direct-mount valve actuators.
These bidirectional actuators are used to provide
accurate positioning on Johnson Controls® VG1000
Series 1/2, 3/4, and 1 in. (DN15, DN20, and DN25) ball
valves in Heating, Ventilating, and Air Conditioning
(HVAC) applications. A mechanical spring return
system provides rated torque with or without power
applied to the actuator. The series includes the
following control options:
• On/Off, 24 V, or 85 to 264 VAC power
• On/Off and Floating Point, 24 V power
• Proportional, 24 V power, for 0(2) to 10 VDC or
0(4) to 20 mA Control Signal
An accessory crankarm and remote mounting kit are
available for applications where the actuator cannot be
direct-coupled to the damper shaft. An optional line
voltage auxiliary switch indicates an end-stop position
or performs switching functions within the selected
rotation range.

Table 1: Features and Benefits (Part 1 of 2)
Features Benefits
Direct Mounting with a Single Screw Reduces installation time and cost.
Electronic Stall Detection Protects from overload at all angles of rotation. Power consumption is
reduced holding mode. The actuator may be stalled anywhere in its
rotation range without the need for mechanical end switches.
Double-Insulated Construction Eliminates need for electrical ground connection for regulatory agency
compliance.
Microprocessor-Controlled Brushless DC
Motor (-AGx and -GGx Models)
Provides constant runtime independent of torque and ensures long life.
External Mode Selection Switch
(-AGx and -GGx Models)
Permits control logic reversal for Floating Control (-AGx Models). Permits
calibration input signal range selection, and control logic reversal for
Proportional Control (-GGx Models).
Integral Cables with Colored and Numbered
Conductors
Simplify installation and field wiring.
Integral 1/2 in. (13 mm) Threaded Conduit
Connector(s)
Simplify installation and field wiring.
Optional Integrated Auxiliary Switch Provides adjustable switch point with line voltage capability.
Plenum Rated Models Enable use in other environmental air spaces (plenums) in accordance
with section 300.22(C) of the National Electric Code.
Optional Thermal Barrier Provides for 284°F (140°C) hot water or 15 psi saturated steam
applications.
