Johnson Controls VG1245DN Valve

Professional-grade control starts with the Johnson Controls VG1245DN, a 1-1/4 inch NPT two-way ball valve engineered for precise HVAC flow regulation. Built with a heavy-duty forged brass body and premium stainless steel trim, this valve is designed to handle demanding hydronic systems, including hot water, chilled water, and 50/50 glycol solutions. The 11.7 Cv rating, combined with a unique equal percentage flow characteristic, ensures linear heat output and stable control even under varying load conditions. For technicians, the Amodel flow characterization disk is a significant advantage, providing the high-accuracy performance of a globe valve with the efficiency of a ball valve. Rated for up to 580 psig static pressure and 15 psi low-pressure steam, this VG1000 series valve features dual EPDM stem seals and 15% graphite-filled PTFE seats, ensuring a leak-free service life exceeding 200,000 cycles. It integrates seamlessly with VA9104, M9100, and VA9200 series actuators for reliable automated performance.

• Equal Percentage Flow: Provides predictable, accurate temperature control across the full range of the actuator stroke.
• Stainless Steel Trim: Enhanced durability and corrosion resistance, essential for low-pressure steam applications.
• Maintenance-Free Design: Dual EPDM stem seals eliminate the need for packing adjustments or rebuilding in the field.
• Compact Installation: The small footprint of the forged brass body allows for easier piping in tight mechanical rooms or cabinet spaces.
• High Close-Off Pressure: Offers a 200 psid close-off rating to prevent bypass and system inefficiencies.

What actuators are compatible with the VG1245DN?
This valve is designed for direct mounting to Johnson Controls VA9104 and M9109 non-spring return actuators, as well as VA9203 and VA9208 spring-return models.

Can this valve be used for steam?
Yes, because this model features stainless steel trim, it is rated for low-pressure steam up to 15 psig. Models with brass trim are not suitable for steam service.

Does the 11.7 Cv rating meet my system requirements?
The 11.7 Cv is ideal for 1-1/4 inch piping where high-precision throttling is required without the significant pressure drop associated with smaller port valves.
