Johnson Controls VG1241FS Valve

The Johnson Controls VG1241FS is a high-performance 2-way ball valve engineered for precision flow control in commercial HVACR systems. Built with a forged brass body and plated brass trim, this 2-inch valve features an equal percentage flow characteristic, making it an ideal choice for regulating chilled water, hot water, and 50% glycol solutions. With a high 46.8 Cv rating and a 500:1 rangeability, it ensures accurate modulation even under varying load conditions. Designed for seamless integration with VA9000 series actuators, the VG1241FS utilizes an Amodel flow characterization disk to maintain linear control and eliminate the need for additional pipe reducers. The NPT threaded connections provide a secure fit, while the dual EPDM stem seals and graphite-reinforced PTFE seats deliver a leak-free ANSI Class IV rating up to 200,000 cycles. Whether you are performing a field replacement or a new installation, this VG1000 series valve is optimized for durability and maintenance-free operation in demanding hydronic environments.

• Precise Flow Modulation: The integrated equal percentage flow disk ensures stable temperature control in air handlers and heat exchangers.
• High Close-Off Pressure: Engineered to handle a maximum close-off pressure of 200 psid, preventing leakage in high-head applications.
• Rugged Construction: Features a forged brass body and blowout-proof stem for long-term reliability in industrial piping.
• Extended Service Life: Self-adjusting EPDM stem seals are rated for over 200,000 cycles, reducing downtime and maintenance costs.
• Superior Rangeability: A 500:1 rangeability allows for fine-tuned control across the entire stroke of the ball valve.

Is the VG1241FS compatible with steam applications?
No, this specific model features plated brass trim and is rated for hot and chilled water or glycol only. For steam service up to 15 psig, a stainless steel trim model must be used.

Which actuators are compatible with this 2-inch valve?
This valve is designed to work with Johnson Controls VA9104, M9106, M9109, VA9203, and VA9208 series actuators, supporting both spring and non-spring return configurations.

What is the maximum fluid temperature for this unit?
The VG1241FS is rated for fluid temperatures ranging from 23°F to 203°F (-5°C to 95°C) at a maximum static pressure of 580 psig.
