The Johnson Controls VA-7482-1001-RA is a proportional electric terminal unit valve actuator. It operates on 24 VAC, delivers 120 N force, has a 3.2 mm stroke, and completes full travel in about 8 seconds. It is designed for HVAC zone valves with reverse acting (RA) functionality.

• Series: Part of the VA-748x actuator family, which includes floating, proportional, and proportional models with feedback.
• Function: Provides precise proportional control of HVAC terminal unit valves, enabling smooth modulation of water flow in heating and cooling systems.
• Reverse Acting (RA): In this configuration, the actuator extends when de-energized and retracts when energized, making it suitable for specific valve sequencing requirements.
• Applications: Fan coil units, chilled ceilings, manifolds, and pressure-independent control valves (PICVs).
• Design: Compact size allows installation in confined spaces, with auto-stroke detection for compatibility with valves of varying stroke lengths.
