VG1241CL+9T4GGA Johnson Controls Valve / Actuator

Overview

The Johnson Controls VG1241CL+9T4GGA is a 1-inch, 2-way electric ball valve assembly designed to provide precise flow control within commercial HVAC and building automation systems. It combines a high-quality forged brass valve body with a VA9104-GGA-3S non-spring-return electric actuator. The assembly features an equal percentage flow characteristic for stable control loop performance and uses a chrome-plated brass ball with a nickel-plated brass stem alongside EPDM O-rings and graphite-reinforced PTFE seats for durable, leak-free operation over a long lifespan.

Features

• High-durability design with a minimum life expectancy of 200,000 full cycles.
• Equal percentage flow characteristics for accurate and linear thermal control.
• Integrated factory-mounted valve linkage for quick installation and streamlined, precise control.
• Manual override capability allows for easy manual positioning of the ball valve during startup or maintenance.
• Synchronous drive mechanism ensures constant rotation time independent of the connected fluid load.
• NEMA 1 (IP40) rated actuator enclosure providing standard indoor protection.
• Low-noise operation rated at 35 dBA to meet strict audible noise requirements in occupied spaces.
• Removable M3 screw terminals to simplify field wiring and reduce overall installation time.
