Johnson Controls VA9203-GGB-2Z Actuator

The Johnson Controls VA9203-GGB-2Z is a high-performance proportional spring return actuator designed for the precise positioning of ball valves in HVACR systems. Operating on a 24VAC/VDC power supply, this direct-coupled actuator delivers 27 lb-in (3 Nm) of torque, making it ideal for managing v-port ball valves in variable air volume and air handling units. It accepts a wide range of control signals, including 0-10 VDC, 2-10 VDC, and (0)4-20 mA with a 500-ohm resistor, providing versatile integration with modern building automation systems. Engineered for durability, it features a 90-second power-on run time and a robust spring return mechanism that ensures a fail-safe position upon loss of power. The inclusion of a 48-inch appliance cable and a single SPDT auxiliary switch allows for simplified field wiring and position feedback, reducing installation overhead for contractors troubleshooting complex HVAC control sequences.

Key Technical Benefits:

• Universal Signal Input: Supports 0-10 VDC modulation and mA signals for seamless compatibility with standard HVAC controllers.
• Integrated Safety: Mechanical spring return function provides reliable fail-safe operation during power interruptions.
• Simplified Monitoring: One SPDT auxiliary switch comes standard for remote verification of valve status and system interlocks.
• Rugged Construction: Compact NEMA 2 housing protects internal components in demanding mechanical room environments.
• Flexible Installation: The direct-coupled design eliminates the need for complex linkages, ensuring high repeatable accuracy.

Common Questions:

Can the VA9203-GGB-2Z be used for 4-20mA control?
Yes, this modulating actuator can accept a 4-20mA signal by utilizing an external 500-ohm resistor to convert the input to a 2-10 VDC control range.

Is the shaft rotation reversible?
The direction of rotation is determined by the mounting orientation on the valve body, allowing for either clockwise or counter-clockwise fail-safe operation depending on site requirements.

How do I wire the auxiliary switch?
The integrated SPDT switch provides a dry contact rated for signaling. Refer to the internal wiring schematic to ensure correct integration with your controller's feedback loop.
