Description
The Johnson Controls VA9203-GGB-2Z is a high-performance, spring return direct coupled ball valve actuator engineered for precise proportional control in commercial HVAC and building automation applications. Designed for reliability and versatility, this actuator accepts multiple input signal types and delivers consistent, repeatable valve positioning across a wide range of system configurations.
Power & Signal Compatibility
- Dual-voltage power supply: 24 Vac / 24 Vdc
- Proportional control signal inputs: 0–10 Vdc and 2–10 Vdc
- Current input: (0)4–20 mA with integrated 500 Ohm resistor — no external resistor required
- Compatible with a broad range of building automation and DDC control systems
Actuator Performance
- Torque output: 27 lb-in — suitable for demanding ball valve applications
- Spring return fail-safe operation: automatically returns valve to safe position on power loss
- Power-on run time: 90 seconds for full stroke travel
- Direct coupled design for tool-free, fast installation onto ball valve stems
Wiring & Connectivity
- 48-inch appliance cable for flexible field wiring and easy routing
- Integrated 1 SPDT auxiliary switch for end-of-travel feedback, interlock, or status signaling
