Johnson Controls VA7830-HGA-2 Electric Valve Actuator 24V Spring Return 0-10VDC Control

The Johnson Controls VA7830-HGA-2 is a 24-volt electric valve actuator from the VA7800 Series, designed for precise control of HVAC dampers and valves. This spring return actuator features a fail-safe spring-down design that returns to the closed position upon power loss, making it ideal for applications requiring safety positioning.

Key Features:

• 24VAC power supply with 11 VA power rating for reliable operation
• 0-10 VDC proportional control signal for precise modulation
• Spring return down (fail-safe closed) operation for safety applications
• Compact design suitable for HVAC valve and damper control
• Direct-coupled mounting for easy installation on compatible valves
• Reliable performance in commercial and industrial building automation systems

This actuator is commonly used in variable air volume (VAV) systems, fan coil units, and other HVAC applications where proportional control and fail-safe positioning are required. The 0-10 VDC control input allows integration with building automation systems and DDC controllers for precise temperature and airflow management.
