VA9104-IGA-3S Johnson Controls Valve Actuator

Overview

The Johnson Controls VA9104-IGA-3S is a professional-grade, non-spring return electric valve actuator designed for use with ball valves in commercial HVAC and building automation applications. Operating on 24 VAC, it features a direct-coupled mount to provide accurate, dependable positioning for hydronic or water-based systems. A built-in manual override handle provides local control during emergency operation or system commissioning, and the actuator is designed to maintain its last position in the event of a power interruption.

Features

• Whisper-quiet operation with a 35 dBA nominal audible noise rating suitable for open ceiling environments.
• Synchronous drive mechanism provides a constant rotation time independent of the load.
• Long-term reliability rated for 100,000 full stroke cycles and 2,500,000 repositions.
• Tool-free, direct mounting with a single screw minimizes installation time and field cost.
• Auto-shutoff feature with an integrated timeout function prevents excessive motor wear.
• Manual override handle allows local valve positioning independent of a power supply.
• Screw terminal wiring provides secure, reliable electrical connections.

Applications

The VA9104-IGA-3S is engineered to provide accurate, direct-mount positioning on Johnson Controls VG1000 Series ball valves (specifically sizes 1/2 in., 3/4 in., and 1 in.) used in commercial heating, ventilating, and air conditioning systems. It is ideally applied in zone control configurations, variable air volume (VAV) reheat units, and other hydronic applications requiring floating or two-position modulation without a fail-safe spring return requirement.
