Description
The Johnson Controls VA9104-GGA-2S is a high-performance, non-spring return direct coupled ball valve actuator engineered for precise proportional control in commercial HVAC and building automation applications. Designed to deliver reliable, repeatable valve positioning, this actuator accepts multiple control signal inputs and features a generous 120-inch plenum-rated cable for flexible installation in air-handling environments.
Control & Signal Compatibility
- Supply voltage: 24 Vac
- Proportional control signal inputs: 0–10 Vdc and 2–10 Vdc
- 4–20 mA current input supported via integrated 500-ohm resistor
- Smooth, stepless proportional positioning for precise flow regulation
Mechanical Performance
- Torque output: 35 lb-in — suitable for a wide range of ball valve sizes
- Travel time: 60 seconds for full stroke, ensuring smooth, surge-free operation
- Non-spring return design retains valve position on power loss
- Direct coupled mounting eliminates linkage for simplified installation and reduced maintenance
Wiring & Installation
- 120-inch (10-foot) plenum-rated cable for code-compliant installation in air plenums and ducts
- Manual override handle allows valve positioning during commissioning or power outages
- Direct couple design compatible with standard ball valve stems
Key Benefits
- Versatile signal compatibility (0–10 Vdc, 2–10 Vdc, 4–20 mA) integrates with virtually any BAS or DDC controller
- Plenum-rated cable meets stringent fire and smoke safety requirements
- Manual override handle simplifies commissioning and emergency operation
- Non-spring return operation conserves energy and maintains last position on power interruption
- Robust Johnson Controls engineering for long service life in demanding commercial environments
