Johnson Controls VG1241BL Ball Valve

The Johnson Controls VG1241BL is a heavy-duty 3/4 inch NPT ball valve engineered for precise proportional control in commercial HVAC systems. This 2-way control valve features a 7.4 Cv flow coefficient and a forged brass body designed to withstand high-cycle applications. Built with an internal Amodel flow characterizing disk, it maintains a true equal percentage flow characteristic, ensuring stable temperature regulation even at low load conditions. The plated brass trim and 15% graphite-filled PTFE seats provide a tight shutoff with an ANSI Class IV leakage rating, making it a reliable choice for chilled water, hot water, and 50% glycol solutions. Designed for direct-coupled actuator mounting, this valve supports field installation with VA9104 or VA9203 series motors. The blowout-proof stem and dual EPDM O-ring seals are rated for up to 200,000 cycles, providing the long-term durability required for building automation and hydronic control applications.

• Equal Percentage Flow: Integrated Amodel disk ensures linear temperature response and prevents hunting in the control loop.
• High Close-Off Pressure: Rated for up to 200 psid close-off, ensuring the HVAC ball valve prevents unwanted flow during off-cycles.
• Maintenance-Free Design: Features dual EPDM stem seals and reinforced seats that require no packing adjustments or rebuilding.
• Extreme Durability: Tested for 200,000 leak-free cycles in iron-oxide contaminated water, exceeding standard commercial requirements.

• Can this valve be used for steam applications? This specific model with plated brass trim is rated for water and glycol only; stainless steel trim models are required for low-pressure steam service.
• What is the maximum fluid temperature for the VG1241BL? It is designed to handle fluid temperatures ranging from 23°F to 203°F (-5°C to 95°C).
• Does this include the actuator? This part number refers to the valve body only; actuators must be sourced separately based on the required torque and control signal.
