Description
Johnson Controls VA-7700-GGA-2 Proportional Valve Actuator Overview
The Johnson Controls VA-7700-GGA-2 is a 24-volt, non-spring-return (NSR) proportional valve actuator engineered for precise modulating control in commercial and light industrial HVAC hydronic systems. Designed to work in tandem with compatible Johnson Controls valve bodies, this actuator delivers smooth, accurate flow regulation to optimize system efficiency and occupant comfort.
Key Features
- 24V AC/DC operating voltage for broad system compatibility
- Non-spring-return (NSR) design — actuator holds last position on power loss
- Proportional (modulating) control for precise, stepless flow adjustment
- Engineered for use with Johnson Controls VA-7700 series valve bodies
- Compact, robust construction suited for demanding commercial HVAC environments
- Reliable performance in heating, cooling, and heat pump hydronic applications
Application
The VA-7700-GGA-2 actuator is ideal for use in variable air volume (VAV) systems, fan coil units, air handling units, and hydronic heating and cooling coil control. Its proportional modulating action enables tight temperature and flow control, reducing energy consumption and improving overall system performance.
