Johnson Controls VA-7480-0312 Actuator
The Johnson Controls VA-7480-0312 is a professional-grade 24V electric valve actuator designed for reliable on/off or floating control in demanding HVAC applications. Engineered for seamless field mounting, this unit is the direct VA-7450-10011 replacement, fitting VG4000 and VG5000 series zone valves without the need for additional linkages. This non-spring return actuator features an auto-commissioning routine that identifies the valve stroke automatically, eliminating manual calibration in the field. Its compact, NEMA 2 (IP43) rated enclosure is constructed from heat-stabilized plastic, making it suitable for fan coil units and confined spaces where fluid temperatures reach up to 203?F. The VA-7480-0312 utilizes a 90-second timeout to protect the motor from excessive wear, ensuring long-term positioning accuracy with 21.5 lb of minimum output force. Whether managing 2-way or 3-way mixing valves, this Johnson Controls actuator provides high-torque performance and 18 AWG cable connectivity for streamlined integration into building automation systems.
Key Benefits for Contractors- Direct Compatibility: Engineered as a drop-in VA-7450-10011 replacement for existing Johnson Controls VG4000/VG5000 valve bodies.
- Reduced Maintenance: Integrated auto-shutoff motor technology prevents burnout by timing out after the stroke is completed.
- Fast Installation: Features auto-commissioning for stroke detection, requiring no specialized tools or field adjustments.
- Visual Diagnostics: Includes a high-visibility green LED operating status indicator for immediate local troubleshooting.
- Flexible Mounting: Can be rotated 360 degrees after installation to solve wiring entry challenges in tight mechanical closets.
Is the VA-7480-0312 compatible with third-party valves?
Yes, the auto-stroke detection system allows this 24VAC floating actuator to adapt to various terminal unit valves and pressure-independent control valves (PICV) with variable strokes.
How do I wire this for floating vs. on/off control?
For floating control, the system uses three-wire connectivity (Black: Common, Red: Extend, Orange: Retract). On/off control is achieved via the same wiring through an SPDT controller signal.
Can I install this in a plenum environment?
While the VA-7480-0312 uses high-grade mineral-filled plastic, always verify local building codes regarding exposed materials in return air plenums before finalizing the install.
