Johnson Controls VA9104-IGA-3S Actuator

The Johnson Controls VA9104-IGA-3S is a high-performance non-spring return electric valve actuator engineered for precise control of VG1000 Series ball valves. Operating on 24Vac power, this direct-mount unit delivers a consistent 35 lb-in torque (4 N-m), ensuring reliable positioning for HVAC applications involving hot water, chilled water, or 50% glycol solutions. The floating control with timeout feature is specifically designed to prevent motor burnout by automatically shutting off power after the 60-second travel time is achieved, significantly extending the service life of the synchronous motor drive.

For contractors, the VA9104-IGA-3S offers a streamlined installation with M3 screw terminals and a single-screw direct-coupling mechanism that eliminates the need for complex linkages. The integrated manual override handle allows for field adjustments without power, while the whisper-quiet 35 dBA noise rating makes it ideal for open-ceiling environments. This direct-coupled actuator is compatible with valve sizes from 1/2" up to 1", providing a robust solution for terminal unit and air handling applications where on/off or floating control is required.

• Precision Control: Utilizes a synchronous motor for constant 60-second rotation independent of load.
• Enhanced Protection: Features an integrated auto shutoff timeout to protect internal gears and motor components.
• Field Flexibility: Includes a manual override for immediate valve positioning during commissioning or power failure.
• Contractor Friendly: Simplified screw terminal wiring and direct-mount design reduce labor time on the job site.
• Quiet Operation: Rated at 35 dBA to meet strict noise requirements in occupied commercial spaces.

Common Questions

Is the VA9104-IGA-3S compatible with 3-way valves?
Yes, it is designed for use with both 2-way and 3-way Johnson Controls VG1000 Series ball valves up to 1 inch in size.

Does this actuator require a special mounting kit?
No, it features a direct-coupled design that mounts directly to the valve flange with a single screw.

What is the purpose of the timeout feature?
The floating control with timeout cuts power to the motor after 60 seconds of drive time, preventing excessive wear and ensuring the non-spring return motor remains operational for its full cycle rating.
