Johnson Controls VA7820-HGA-2 Electric Valve Actuator

The Johnson Controls VA7820-HGA-2 Electric Valve Actuator delivers precise proportional control for HVAC dampers, enabling accurate flow modulation across building systems. This spring-return actuator operates on 24V AC and accepts a 0–10 VDC control signal for reliable damper positioning.

Ideal for commercial and industrial HVAC, it supports 50/60 Hz, draws 20 mA, and provides up to 11 VA of power, with an SPDT limit switch for fail-safe positioning. The unit outputs a 0–10 VDC control signal and features a robust IP54/NEMA 2 enclosure for demanding environments.

Its compact footprint and durable materials reduce installation time and maintenance needs, making it a trusted choice for modern HVAC control systems.

The rugged construction combines a resin ABS/PC body with a die-cast aluminum yoke, and it measures 4.56 x 8.35 x 9.6 inches. The 3/8 in flexible metal conduit supply connection simplifies installation, while UL and CE approvals ensure compliance and reliability.
