VA9104-AGA-3S Johnson Controls Valve Actuator

Overview

The Johnson Controls VA9104-AGA-3S is a direct-coupled, non-spring return electric valve actuator designed to provide precise two-position and floating control for ball valves in commercial HVAC systems. This synchronous motor-driven actuator ensures accurate positioning and maintains its last position upon a loss of power.

Features

• Non-spring return design preserves valve positioning during power interruptions
• Integrated manual override handle enables manual adjustment during commissioning or power outages
• Screw terminal block provides secure, vibration-resistant field wiring connections
• Synchronous motor delivers a constant rotation speed independent of the system load
• Direct coupled mounting allows for fast, tool-free installation on compatible valves

Specifications

• Supply Voltage: 24 VAC, 50/60 Hz
• Control Input: Two-Position and Floating without timeout
• Output Torque: 35 lb-in (4 N-m)
• Full Stroke Travel Time: 60 seconds at 60 Hz (72 seconds at 50 Hz)
• Enclosure Rating: NEMA 2
• Ambient Temperature Range: -4 to 140 degrees Fahrenheit

Applications

• Engineered for accurate modulation and control of Johnson Controls VG1000 Series ball valves
• Ideal for hydronic heating and cooling applications, such as chilled and hot water coil control
• Suitable for integration within commercial HVAC systems and building automation setups
