Johnson Controls VG1245FS Valve

The Johnson Controls VG1245FS is a heavy-duty 2-inch NPT ball valve engineered for precise control in commercial HVAC systems. As a key component of the VG1000 Series, this two-way control valve features a 46.8 Cv rating and an Amodel flow characterizing disk. This design ensures an equal percentage flow characteristic, providing linear temperature control and high rangeability that standard ball valves lack. Built with a forged brass body and 300 series stainless steel trim, it is rated for a static pressure of 580 psig and a close-off pressure of 200 psi. The stainless steel ball and stem allow for compatibility with chilled water, hot water, 50% glycol solutions, and even 15 psi saturated steam. Reliable operation is supported by EPDM double O-ring stem seals and graphite-reinforced PTFE seats, tested for over 200,000 cycles to maintain tight shutoff in demanding conditions. This valve is designed for seamless integration with VA9104, VA9203, and VA9300 series electric actuators.

• Precise Modulation: The integrated flow disk delivers equal percentage flow for stable hunting-free temperature regulation.
• Steam Compatible Trim: 300 series stainless steel trim enables safe operation in low-pressure steam applications up to 15 psi.
• High Close-Off Performance: Provides a tight ANSI Class IV leakage rating with a 200 psi close-off pressure for reliable isolation.
• Durable Seal Design: Graphite-reinforced PTFE seats and EPDM O-rings are specifically optimized for iron-oxide contaminated water systems.
• Extended Service Life: Maintenance-free construction rated for 200,000 cycles, reducing long-term system downtime for contractors.

What is the maximum media temperature for the VG1245FS?
With the stainless steel trim, this valve can handle media temperatures ranging from -22°F to 284°F (-30°C to 140°C), making it suitable for both chilled water and high-temperature water applications.

Is this valve compatible with spring-return actuators?
Yes, the VG1245FS is compatible with the Johnson Controls VA9203 and VA9208 series spring-return actuators, as well as several non-spring return models for various control signals.

Can I use this for a 50% glycol loop?
Absolutely. The internal materials, including the EPDM seals and forged brass body, are fully compatible with water-to-glycol mixtures up to a 50/50 ratio.
