VA9104-GGA-3S Johnson Controls Valve Actuator

Overview

The Johnson Controls VA9104-GGA-3S is a high-performance, non-spring return electric valve actuator designed to operate on AC 24 V power. It provides precise, proportional control for modulating positioning on Johnson Controls VG1000 Series ball valves within commercial HVAC and building automation systems.

Features

• Whisper-quiet operation with a 35 dBA nominal audible noise rating suitable for open ceilings.
• Synchronous drive ensures constant rotation time independent of the load.
• Manual override handle enables easy positioning without power supply.
• Direct-mount design with a single screw minimizes installation costs and time.
• Long-lasting durability rated for up to 100,000 trouble-free cycles.
• Integrated M3 screw terminals simplify field wiring.

Specifications

• Supply Voltage: AC 24 V, 50/60 Hz, 2.9 VA rating.
• Torque Output: 35 lb-in (4 N-m).
• Control Signal: 0-10 VDC, 2-10 VDC, or 4-20 mA (with field-furnished 500 ohm resistor).
