Johnson Controls VA7810-HGC-2 Actuator

The Johnson Controls VA7810-HGC-2 Actuator is a field-proven non-spring return direct coupled globe valve actuator designed for the precise modulation of VG7000 Series bronze globe valves. This 24Vac electric valve actuator delivers a consistent 180 lb-in torque (800 N thrust), making it a reliable choice for chilled water, hot water, and steam applications. Its multifunctional design supports on/off, floating control, and proportional signals—including 0-10Vdc, 2-10Vdc, and 4-20mA—selectable via onboard DIP switches to match any HVAC control system requirements.

Built for the job site, the VA7810-HGC-2 features an integrated SPDT auxiliary switch for position signaling and a brush-less motor coupled with force-controlled shut-off to prevent valve seat wear. The automatic stroke adjustment and self-calibrating logic eliminate manual setup errors, while the 48-inch halogen-free cable and NEMA 2 (IP54) housing ensure a rugged installation. A manual override allows for fast positioning during commissioning or emergency servicing without power.

• Universal Control Compatibility: Supports proportional, floating, and two-position signaling for maximum field flexibility.
• Precise Valve Protection: Force-controlled motor shut-off stops the actuator when the valve reaches its seat, protecting the assembly from excessive mechanical force.
• Fast Commissioning: Features a unique swing-gate yoke for secure attachment and self-calibrating stroke limits during the first cycle.
• Field Serviceability: Includes a manual override crank and a clear visual stroke position indicator for immediate status checks.
• Extended Durability: The brushless motor design reduces energy consumption and provides high-cycle performance in demanding HVACR environments.

Which valve series is compatible with the VA7810-HGC-2?
This actuator is specifically engineered for Johnson Controls VG7000 Series globe valves with stroke lengths ranging from 5/16" to 1".

How do I handle a loss of power with this model?
As a non-spring return actuator, the VA7810-HGC-2 will fail-in-place upon loss of power. For manual positioning, use the included override crank located under the cover.

Can I use a 4-20mA signal for modulation?
Yes, this unit is field-configurable for current signals (0-20mA or 4-20mA) by adjusting the internal DIP switches and utilizing the appropriate wiring terminals.
