Johnson Controls VA9208-GGA-2 Actuator

The Johnson Controls VA9208-GGA-2 is a professional-grade spring return electric valve actuator engineered for precise proportional control of VG1000 Series ball valves, specifically sizes 1-1/4, 1-1/2, and 2 inch. Operating on a versatile 24 Vac/Vdc power supply, this 70 lb-in torque actuator supports multiple control signals, including 0-10 Vdc, 2-10 Vdc, and—with the integrated 500 Ohm resistor—4-20 mA circuits. The unit is designed for direct-coupled mounting using a single screw, which significantly reduces field installation time for mechanical contractors. Built for longevity in rigorous HVAC environments, it features a microprocessor-controlled brushless DC motor that provides a constant 150-second runtime regardless of load and includes electronic stall detection to prevent motor burnout. The 120-inch plenum-rated cable and integral 3/8-inch FMC connector allow for seamless integration into environmental air-handling spaces in compliance with NFPA 70 standards. This bidirectional actuator ensures fail-safe operation, returning the valve to its original position during power loss for critical system protection.

• Universal Control Compatibility: Seamlessly interfaces with 0-10Vdc and 4-20mA proportional controllers for high-accuracy modulation.
• Contractor-Friendly Installation: Features a direct-mount design and 120" plenum cable with an integral 3/8" FMC connector for fast wiring.
• Fail-Safe Protection: Reliable mechanical spring return system ensures valves reach a safe position during emergency power loss.
• Enhanced Motor Life: The brushless DC motor and electronic stall detection eliminate the need for end-switches and prevent internal damage.
• NFPA 70 Compliant: Configured specifically for plenum-rated spaces and other environmental air-handling applications.

• Can this actuator be used in steam applications? Yes, when used with stainless steel trim VG1000 valves, it is rated for up to 15 psig steam, provided the valve stem is mounted horizontally.
• How do I switch between 0-10V and 2-10V control? The VA9208-GGA-2 features an external mode selection switch that permits easy calibration and control logic reversal in the field.
• Does this require an electrical ground? No, the double-insulated construction eliminates the need for a separate ground wire, simplifying the electrical setup.
