VA-7482-9002-RA Johnson Controls Actuator

Overview

The Johnson Controls VA-7482-9002-RA is a non-spring return electric terminal unit actuator designed for field mounting onto terminal unit valves. It features an innovative auto-stroke detection system that automatically self-calibrates to the valve’s actual mechanical stroke upon power-up, adjusting for precision control. The unit includes an operating status LED providing direct visual indication of the actuator’s status and can be rotated after mounting to simplify installation.

Features

• Auto-stroke detection and self-calibration capability
• Proportional control mode with configurable analog inputs
• Configurable to direct or reverse action
• Operating status LED for visual indication
• Actuator can be rotated after mounting to facilitate easy wiring entry
• Built-in feedback control and fail-safe operation

Applications

The VA-7482-9002-RA is designed for zone-level hydronic control and is widely utilized in commercial HVAC systems. Its compact build makes it suitable for installation in space-limited environments such as fan coil units, chilled ceilings, induction units, and zone valve control manifolds. It is engineered for direct field mounting onto Johnson Controls VG6000, V5000, VP100, M30x1, and M30x5 Series zone valves, as well as compatible competitor terminal unit valves.
