Johnson Controls VA7810-AGA-2 Actuator

The Johnson Controls VA7810-AGA-2 is a heavy-duty non-spring return actuator designed for the precise control of VG7000 Series bronze globe valves. Operating on 24Vac power, this unit delivers 180 lb-in torque to manage flow in high-demand HVAC systems. This specific model supports both two-position and floating control, providing flexibility for diverse automation sequences. With a 5/16" to 1" stroke range, it ensures accurate valve positioning for heating and cooling applications. The direct-coupled globe valve actuator design eliminates the need for complex linkages, simplifying installation in tight mechanical spaces. It includes a 48" plenum-rated cable for secure electrical connections and a manual override feature, allowing technicians to manually position the valve during commissioning or power failures. Built for longevity in commercial environments, this actuator maintains consistent force throughout its travel to prevent seat leakage and optimize hydronic system performance.

• High Torque Output: Provides 180 lb-in of force to handle high differential pressures without stalling.
• Dual Control Logic: Compatible with both on/off and floating (3-point) 24V controllers.
• Simplified Installation: Direct-coupled mounting reduces labor time and mechanical failure points.
• Manual Operation: Integrated override allows for troubleshooting and system flushing without power.
• Durable Construction: Engineered to withstand the thermal stresses of continuous globe valve modulation.

Is the VA7810-AGA-2 a spring return model?
No, this is a non-spring return actuator. It will maintain its last position upon loss of power unless manually adjusted.

What valves are compatible with this actuator?
It is specifically designed for Johnson Controls VG7000 Series bronze globe valves with a stroke of up to 1 inch.

What is the function of the 48-inch cable?
The factory-installed cable simplifies wiring by providing a ready-to-connect lead for 24Vac power and control signals.
