Johnson Controls VG7841GT Valve

The Johnson Controls VG7841GT is a high-performance 1/2-inch 3-way mixing globe valve engineered specifically for technical precision in HVAC water and steam applications. Utilizing a rugged cast bronze body and durable brass trim, this NPT threaded valve is designed to handle demanding hydronic systems where accurate temperature control is non-negotiable. Featuring a 4.6 Cv rating and equal percentage flow characteristics, the VG7841GT ensures linear control response and stable modulation even under varying pressure drops. This VG7000 series valve is compatible with electric and pneumatic actuators, utilizing a standard threaded stem for seamless field integration. Whether replacing a failing component or installing a new terminal unit system, this valve provides the reliability required for hot water, chilled water, or 15 psig saturated steam. The spring-loaded PTFE V-ring packing provides a superior seal, reducing maintenance intervals and ensuring long-term operational efficiency in commercial building automation systems.

• Precise Flow Control: The equal percentage flow characteristic ensures stable temperature modulation and eliminates hunting in the control loop.
• Material Durability: Constructed with a cast bronze body and brass trim to resist corrosion and withstand high-temperature hydronic environments.
• Versatile Compatibility: Designed for use with both steam and water applications, fitting standard 1/2-inch NPT piping configurations.
• Standardized Integration: The standard threaded stem allows for easy pairing with a wide range of Johnson Controls actuators.
• Reduced Maintenance: Features self-adjusting packing for consistent sealing performance under thermal cycling.
