Johnson Controls VG7481ST Valve

The Johnson Controls VG7481ST is a rugged 2-way normally closed globe valve engineered for precision control in commercial HVACR hydronic systems. Featuring a 2-inch union sweat connection compatible with standard tubing, this cast bronze body valve ensures long-term reliability in high-demand environments. The 46.2 Cv rating and equal percentage flow characteristic provide superior throttling accuracy, making it ideal for managing chilled water or hot water applications. Built with a brass trim and a standard threaded stem, the unit operates via a push-down-to-open action, simplifying actuator integration. This VG7000 series bronze valve is designed for high-pressure installations where maintainability and consistent hydronic flow control are critical for system balancing. Technicians can rely on the VG7481ST globe valve for its robust construction and predictable performance when replacing legacy components or installing new commercial HVAC control valves.

Key Benefits:

• High Flow Capacity: The 46.2 Cv rating facilitates efficient fluid movement in large-diameter piping systems.
• Durable Construction: Cast bronze body paired with brass trim resists corrosion and handles temperature fluctuations.
• Precision Throttling: Equal percentage flow ensures predictable heat transfer across various load conditions.
• Standardized Installation: 2-inch union sweat connections allow for secure, leak-free integration with copper tubing.
• Operational Reliability: Push-down-to-open stem action simplifies setup with matching Johnson Controls electric or pneumatic actuators.

Common Questions:

What is the maximum fluid temperature for the VG7481ST?
