Description
The Johnson Controls VA9104-IGA-2S is a heavy-duty, direct coupled ball valve actuator engineered for reliable performance in commercial HVAC hydronic and building automation applications. Designed for use with floating control or two-position control with timeout functionality, this actuator delivers precise, repeatable valve positioning without the need for a return spring, simplifying installation and reducing mechanical complexity.
Key Features
- 24Vac operating voltage compatible with standard HVAC control systems
- Floating control or two-position control with timeout capability for flexible integration
- 35 lb-in (4 Nm) torque output for dependable actuation of ball valves
- 60-second travel time for smooth, controlled valve operation
- 120-inch (10 ft) plenum-rated cable for safe routing through air plenums and return air spaces
- Non-spring return design — valve holds last position on power loss
- Direct coupled mounting for fast, tool-friendly installation onto compatible ball valves
- Manual override handle included for commissioning, testing, and emergency operation
Control & Wiring
- Accepts floating (tri-state) or two-position (on/off) control signals
- Timeout function protects against overtravel and motor burnout
- 24Vac power supply — compatible with standard building automation and DDC controllers
- Plenum-rated cable meets code requirements for installation in return air plenums
Installation & Mechanical
- Non-spring return operation: actuator holds position when de-energized
- Direct coupled design eliminates linkage for reduced installation time
- Manual override handle allows hand positioning of the valve without electrical power
- Compact form factor suitable for tight mechanical room installations
Ideal Applications
- Hydronic heating and cooling coil control
- Fan coil unit (FCU) valve control
- Variable air volume (VAV) and air handling unit (AHU) hydronic circuits
- Building automation systems (BAS) and direct digital control (DDC) environments
- Commercial and light industrial HVAC systems
The VA9104-IGA-2S is backed by Johnson Controls’ reputation for quality and is an ideal drop-in solution for new construction or retrofit projects requiring dependable, code-compliant ball valve actuation.
