Johnson Controls VG1241DN Valve

The Johnson Controls VG1241DN is a heavy-duty 1-1/4 inch NPT ball valve designed for precise flow control in commercial HVACR chilled or hot water applications. Built with a forged brass body and robust plated brass trim, this two-way valve features an Amodel flow characterizing disk to maintain a strict equal percentage flow. This specific geometry ensures stable thermal control and prevents hunting in modern building automation systems. With a 11.7 Cv rating and a 580 psig static pressure rating, the VG1241DN is engineered to handle high-demand environments. The stem utilizes dual EPDM O-rings and graphite-reinforced PTFE seats, providing a maintenance-free leak-free seal tested through 200,000 cycles. Designed for seamless integration, it is compatible with VA9104, VA9203, and VA9208 series actuators, offering a 200 psi closeoff pressure for secure shutoff in variable flow systems. This industrial-grade control valve is a reliable solution for technicians requiring accurate 500:1 rangeability and long-term durability in sediment-heavy hydronic loops.

• Equal Percentage Flow Control: Internal Amodel characterizing disk ensures linear heat output and stable temperature regulation.
• High Closeoff Protection: Rated for 200 psi closeoff to prevent bypass leakage and maintain system efficiency during idle periods.
• Durable Material Selection: Features a forged brass body and plated brass ball/stem for superior corrosion resistance in hydronic systems.
• Extended Service Life: Dual EPDM O-rings and graphite-reinforced PTFE seats are designed for over 200,000 full-stroke cycles.
• Blowout-Proof Stem: Built-in safety features protect technicians during high-pressure maintenance and installation.

What is the fluid temperature range for this valve?
The VG1241DN with plated brass trim is rated for fluid temperatures ranging from 23?F to 203?F (-5?C to 95?C), making it ideal for chilled and hot water applications.

Is the VG1241DN compatible with steam systems?
No, this specific model with plated brass trim is not rated for steam service. For low-pressure steam applications up to 15 psig, a stainless steel trim assembly is required.

Which actuators fit the 1-1/4" VG1000 series?
This valve is designed for direct mounting with Johnson Controls VA9104 non-spring return actuators or VA9203/VA9208 spring-return electric actuators using standard linkage.
