VA9905-KGA-2 Johnson Controls Actuator

Overview

The Johnson Controls VA9905-KGA-2 is an electric non-spring return rotary valve actuator designed specifically for direct mounting on VG1600 Series 270-degree Six-Way Ball Valves. This actuator efficiently regulates the flow of hot and chilled water in commercial HVAC systems, substituting for either four regular through valves or two through valves and one change-over valve. It features an intuitive, fool-proof mounting system with plastic posts and tabs that align with the valve flange and stem notch to simplify installation and reduce errors. Powered by a microprocessor-controlled brushless DC motor, it provides reliable performance, precise valve positioning, and an integrated position indicator handle with manual override for convenient adjustments.

Features

• Microprocessor-controlled brushless DC motor provides consistent and accurate operation
• Multi-input signal configuration with an eight-position DIP switch for field settings
• Easy-to-use direct-mount assembly system minimizes installation errors
• External position indicator handle and manual override for simple mechanical adjustments
• Plenums-rated cable design allows safe installation in environmental air spaces
• Built under ISO-9001 quality control standards for maximum durability, supporting up to 100,000 full-stroke cycles
