Description
The Johnson Controls VA9203-GGA-2Z is a spring return, direct coupled ball valve actuator engineered for precise proportional control in commercial HVAC and building automation applications. Designed to operate on 24 Vac or 24 Vdc power, this actuator accepts multiple control input signals — including 0–10 Vdc, 2–10 Vdc, and (0)4–20 mA (with an integrated 500 Ohm resistor) — making it highly versatile for integration with a wide range of building automation and DDC control systems.
With a robust 27 lb-in torque output and a 90-second power-on run time, the VA9203-GGA-2Z delivers reliable, repeatable valve positioning. The spring return mechanism ensures the valve returns to its fail-safe position upon loss of power, providing an added layer of system protection. The actuator ships with a generous 120-inch plenum-rated cable, simplifying installation in air-handling and plenum environments where code-compliant wiring is required.
