Johnson Controls VA9203-BUA-2 Actuator

The Johnson Controls VA9203-BUA-2 is a high-performance spring return direct coupled actuator engineered for precise two-position control of ball valves in demanding HVACR applications. Operating on a universal 85-264Vac power supply, this electric actuator delivers a consistent 27 lb-in torque, ensuring reliable valve seating and tight shut-off even in varying pressure conditions. With a power-on run time of less than 75 seconds, it provides responsive automation for air handling units and hydronic systems. The integrated 48-inch appliance cable simplifies field wiring, while the spring return safety mechanism ensures the valve reverts to its fail-safe position during a loss of power. Designed for longevity in commercial environments, the VA9203 series eliminates the need for complex linkages, reducing mechanical failure points and streamlining the installation process for contractors managing large-scale ball valve automation projects.

Technical Benefits

• Universal Voltage Compatibility: The wide 85-264Vac input range allows for versatile installation across different power configurations without additional transformers.
• Fail-Safe Spring Return: Mechanical spring return provides essential system protection by driving the valve to a fail-safe state during power interruptions.
• Direct Coupled Design: Eliminates external linkages, ensuring a more compact footprint and reducing labor time during actuator replacement.
• High Internal Torque: Provides 27 lb-in (3 Nm) of force, optimized for Johnson Controls VG1000 series ball valves.
• Rapid Cycle Time: Efficient motorized valve operation with a drive time under 75 seconds enhances system modulation and energy efficiency.

Common Installation Questions

Can the VA9203-BUA-2 be used for proportional control?
No, this specific model is designed for two-position (on/off) operation. For modulating or 0-10VDC applications, a different series actuator would be required.

How do I change the spring return direction?
The fail-safe direction (normally open or normally closed) is determined by the mounting orientation on the valve linkage. Flip the actuator to change the spring return rotation.

Is the appliance cable plenum rated?
The included 48-inch appliance cable is standard for most mechanical room installations; however, always verify local code requirements if routing through plenum spaces.
