Johnson Controls VA9104-GGA-3S 24V Proportional Electric Valve Actuator 35 lb-in

Description

The Johnson Controls VA9104-GGA-3S is a non-spring-return electric valve actuator designed for proportional control of compatible HVAC valves in commercial heating and cooling systems. Johnson Controls part number VA9104-GGA-3S operates on 24 VAC power and delivers 35 lb-in (4 Nm) of torque with a 60-second running time at 60 Hz. Its configurable 0–10 VDC or 2–10 VDC control input and integrated manual override support precise valve positioning in building automation applications.

Technical Specifications

Information About VA9104-GGA-3S

The VA9104-GGA-3S is part of the Johnson Controls VA9104 Series of electric rotary valve actuators, engineered for modulating control of compatible hydronic valve assemblies. Its compact motor-driven construction incorporates non-spring-return operation, proportional control electronics, and a manual override handle for mechanical positioning during installation or maintenance. The actuator supports voltage control signals of 0–10 VDC or 2–10 VDC and can accept corresponding 0–20 mA or 4–20 mA signals through an external 500-ohm resistor. Designed for HVAC applications involving heating coils, cooling coils, and water-flow regulation, the unit provides controlled valve movement with low electrical power consumption and straightforward terminal connections.

Key Features:

• 35 lb-in Torque Output: Provides 4 Nm of rotary torque for positioning compatible HVAC control valves.

• Proportional Control: Supports modulating valve positioning using configurable analog control signals.

• 24 VAC Power Supply: Operates from a low-voltage AC supply suitable for commercial building automation systems.

• Non-Spring-Return Design: Maintains its mechanical position without automatic spring-driven return during power loss.

• Selectable Voltage Input: Supports 0–10 VDC and 2–10 VDC proportional control signals.

• Current Signal Compatibility: Accepts 0–20 mA or 4–20 mA control through an external 500-ohm resistor.

• 60-Second Running Time: Provides approximately 60 seconds of travel at 60 Hz or 72 seconds at 50 Hz.

• Manual Override Handle: Allows mechanical repositioning of the actuator during installation and servicing.

• Low Power Requirement: Features a rated electrical consumption of 2.9 VA.

• Screw Terminal Connections: Uses M3 screw terminals for field wiring and controller integration.

• Rotary Valve Actuation: Designed for use with compatible Johnson Controls rotary valve assemblies.

• HVAC Automation Integration: Supports proportional water-flow regulation in heating and cooling applications.

The VA9104-GGA-3S delivers the reliability and precision required for modulating hydronic valve control, commercial HVAC temperature regulation, and automated building control systems.
