Johnson Controls VA7810-HGA-2 Actuator

The Johnson Controls VA7810-HGA-2 is a high-performance, non-spring return direct coupled actuator engineered for precise control of VG7000 Series bronze globe valves. Designed for professional HVACR contractors, this unit provides a versatile solution for managing hot water, chilled water, or steam flow. It delivers a robust 180 lb-in torque (800 N linear force) and supports a stroke range of 5/16" to 1", ensuring reliable operation for valves sized 1/2" to 2". As a direct replacement for VA-7202-1001, it streamlines retrofits and system maintenance.

This 24Vac valve actuator supports multiple control protocols, including two-position, floating control, and proportional control. It is field-configurable via DIP switches for various input signals such as 0-10Vdc, 2-10Vdc, and 4-20mA. The integrated brushless motor and force-controlled shut-off mechanism reduce energy consumption and mechanical wear. For commissioning and emergency service, the unit features a standard manual override and an IP54-rated enclosure for protection in demanding mechanical room environments.

• Universal Control Compatibility: Easily switch between 0-10Vdc proportional, floating, or on/off control signals to match any building automation system.
• Simplified Commissioning: Features automatic stroke adjustment and a unique swing-gate yoke for fast, secure attachment to globe valves.
• Enhanced Diagnostics: The multi-colored LED provides real-time status and failure analysis, while the 48-inch cable simplifies field wiring.
• Precise Positioning: High-resolution control allows for exact valve modulation, improving thermal stability and system efficiency.

• What valves is this actuator compatible with? It is specifically designed for 1/2" to 2" Johnson Controls VG7000 Series Globe Valves.
• Does it require a separate mounting kit? No, the direct-coupled swing-gate yoke allows for immediate field mounting to compatible valve bodies.
• Can I manually adjust the valve for testing? Yes, the built-in manual override allows technicians to position the valve without power during startup or service.
