Johnson Controls VA-7482-8002-RA Proportional Electric Valve Actuator (24 VAC/DC, 120 N, 6.3 mm Stroke)

Overview

The VA-7482-8002-RA is part of Johnson Controls’ VA-748x series of electric valve actuators. It provides proportional control (analog input), is rated for 120 Newtons of force, and offers a maximum stroke of 6.3 mm (0.25 in). It is designed for use with various terminal unit valves or Pressure Independent Control Valves (PICVs), making it suitable in fan coil / HVAC applications. The actuator features an IP43 / NEMA 2 enclosure, and supports variable analog signal input options.

Key Features & Benefits

• Proportional (0-10 V / configurable analog) control for precise valve positioning. Johnson Controls Documentation

• Strong output force (120 N) to actuate valves under load.

• Compact mechanical stroke up to 6.3 mm (0.25 in) for compatibility with many valve designs. Johnson Controls Documentation

• IP43 enclosure (NEMA 2) which gives basic protection from solid objects and limited water spray – good for indoor HVAC applications. Johnson Controls Documentation

• Multiple analog input signal options and configurable “direct” or “reverse” acting behavior. Johnson Controls Documentation

Technical Specifications

Applications

• Designed for fan coil units, VAV boxes, and terminal unit valves in HVAC systems.

• Compatible with Pressure Independent Control Valves (PICVs) for energy-efficient hydronic balancing.

• Provides proportional control for hot water, chilled water, or low-pressure steam systems.

• Commonly used in building automation systems (BAS) to achieve precise temperature and flow regulation.

Installation & Best Practices

• Verify power supply: 24 VAC ±15% or 24 VDC ±15% before wiring.

• Ensure correct wiring for proportional 0-10 VDC input signal; confirm “direct” or “reverse” acting per system requirements.

• Mount actuator vertically above the valve body where possible to prevent moisture ingress.

• Allow for full 6.3 mm stroke travel without mechanical obstruction.

• Perform a functional test after installation to confirm actuator stroke matches the valve range.

• Avoid exposure to dust, condensation, or vibration beyond rated environmental conditions.
