Johnson Controls VA9104-AGA-2S Electric Non-Spring Return Valve Actuator

The Johnson Controls VA9104-AGA-2S is a compact, electric non-spring return valve actuator designed for precise control in HVAC systems, particularly for chilled water, hot water, and steam applications. This actuator delivers 4 Nm (35 in-lb) of torque, making it suitable for operating ball valves, globe valves, and other compatible valve types in building automation and industrial settings. Key features include synchronous motor-driven operation, a 0-10 VDC or 4-20 mA proportional control signal compatibility, and a manual override for easy commissioning and maintenance. Its advantages over similar products include reliable performance in demanding environments, low power consumption (2 VA), and easy installation with a direct-mount design that reduces setup time. Benefits encompass energy efficiency, quiet operation, and long service life, while drawbacks may include the lack of spring return for fail-safe positioning in power loss scenarios, requiring additional components for such needs. Ideal for applications in commercial buildings, data centers, and process control, it offers superior accuracy and integration with Johnson Controls' Metasys system compared to generic actuators.
