Johnson Controls VA9104-AGA-3S Actuator

The Johnson Controls VA9104-AGA-3S Actuator is a professional-grade solution designed for precise control of VG1000 Series ball valves in demanding HVACR environments. Built as a non-spring return valve actuator, this unit delivers 35 lb-in torque to manage DN15, DN20, and DN25 valves with high reliability. It operates on 24Vac power and supports both two-position and floating control protocols. Unlike standard models, the -AGA variant is a floating control without timeout version, necessitating a controller or software that includes a timeout function at the end of rotation to prevent unnecessary motor wear. The synchronous motor ensures a consistent 60-second travel time for 90 degrees of rotation at 60 Hz, providing stable modulation. For field integration, the M3 screw terminals facilitate secure wiring, while the integrated manual override handle allows for immediate mechanical adjustments during commissioning or maintenance without disrupting the drive train.

• Direct-Coupled Versatility: Seamlessly mounts to HVAC ball valves in four 90-degree increments for flexible piping layouts.
• Industrial Durability: Rated for over 100,000 cycles, ensuring long-term performance in building automation systems.
• Manual Control: Equipped with a keyed manual override handle for emergency positioning and system testing.
• Efficient Power Usage: Minimal 2.3 VA power requirement makes it ideal for multi-actuator configurations on a single Class 2 transformer.

• How do I wire the VA9104-AGA-3S for floating control? Utilize the M3 screw terminals for a 3-wire connection; however, ensure your controller provides the end-of-travel timeout to protect the motor, as this model lacks internal auto-shutoff.
• Is this actuator compatible with steam valves? It is compatible with VG1000 valves for low-pressure steam (up to 15 psig) when the optional M9000-561 thermal barrier is installed.
• What is the difference between this and the -GGA model? The AGA-3S is designed for floating control, whereas the GGA model is intended for 0-10V proportional signals.
