Johnson Controls VA9104-GGA-3S Actuator

The Johnson Controls VA9104-GGA-3S is a non-spring return direct-coupled ball valve actuator engineered for precise proportional control in commercial HVAC and building automation systems. Operating on 24 VAC power, this unit delivers a consistent 35 lb-in torque, making it a reliable choice for driving VG1000 series ball valves. The actuator is field-configurable for multiple control signals, including 0-10 VDC, 2-10 VDC, and, with the included 500-ohm resistor, 4-20 mA inputs. This flexibility makes it indispensable for modulating control of hot water, chilled water, or low-pressure steam units. Technical features include a 60-second travel time at 60 Hz and M3 screw terminals for efficient field wiring. The integrated manual override handle allows for local positioning during commissioning or system testing, ensuring the proportional valve actuator maintains optimal performance without the need for additional specialized tools in tight mechanical spaces.

Key Benefits for Technicians:

• Universal Field Integration: Supports 0(2)-10 VDC or 4-20 mA signals, allowing for seamless replacement in diverse BAS (Building Automation Systems) architectures.
• Quick Installation: Features M3 screw terminals and a direct-coupled design that eliminates the need for complex mounting linkages on Johnson Controls ball valves.
• Mechanical Versatility: The 35 lb-in torque rating and non-spring return operation provide stable positioning for specific HVAC zones and air handling units.
• Manual Control: Built-in manual override permits manual valve positioning for system balancing or emergency operation without disconnecting power.

Common Questions:

Can the VA9104-GGA-3S be used for 4-20 mA control?
Yes, this model includes a 500-ohm resistor that enables 4-20 mA proportional control when wired across the input terminals, providing versatility for different controller outputs.

What is the difference between this and a spring return model?
As a non-spring return actuator, the VA9104-GGA-3S maintains its last position upon loss of power. For applications requiring a fail-safe open or closed position, a spring-return series should be specified.

Does this actuator require a specific valve body?
It is specifically designed for direct mounting to VG1000 series ball valves, ensuring matched torque requirements and proper alignment for proportional flow control.
