Product Description P/N: VA7830-HGA-2
Description
The Johnson Controls VA7830-HGA-2 is a spring return electric valve actuator designed to control VG7000 Series bronze globe valves in HVAC systems. It operates on 24 VAC power and provides a minimum 180 lb-in (800 N) linear thrust with fail-safe stem-down operation when power is lost. Automatic calibration, manual override, and visual position indicators support accurate commissioning and service.

Information About VA7830-HGA-2
The VA7830-HGA-2 is a Johnson Controls actuator intended for hydronic heating and cooling, air handling, and building automation applications. Its brushless motor and force-controlled shut-off design provide controlled movement while helping reduce mechanical wear. The actuator supports proportional control signals including 0–10 VDC, 2–10 VDC, 0–20 mA, and 4–20 mA, with selectable actuation speeds of 76 or 152 seconds per inch. A built-in 48-inch cable with colored conductors simplifies electrical connection during installation.
Key Features:
- 24 VAC Operation: Uses a 24 VAC supply for reliable HVAC valve actuation.
- Spring Return: Drives the valve stem to the fully extended position when power is removed.
- 180 lb-in Thrust: Provides a minimum linear output force of 800 N for compatible globe valves.
- Automatic Calibration: Supports automatic setup and precise stroke adjustment during commissioning.
- Manual Override: Allows manual positioning with a 5 mm Allen wrench when power is disconnected.
- Proportional Control: Accepts 0–10 VDC, 2–10 VDC, 0–20 mA, or 4–20 mA control inputs.
- Visual Indication: Uses a status LED and colored stroke indicator for operating and position information.
- IP54 Housing: Provides environmental protection for suitable HVAC installation conditions.
The VA7830-HGA-2 delivers the reliability and precision required for spring return HVAC globe valve actuation.
