Johnson Controls VG1245DR Valve

The Johnson Controls VG1245DR is a high-performance 1 1/4" NPT ball valve engineered for precise control in commercial HVAC systems. This two-way control valve features a 29.2 Cv rating and an equal percentage flow characteristic, ensuring stable modulating control of hot water, chilled water, or 50% glycol solutions. Built with a rugged forged brass body and 300 series stainless steel trim, this unit is designed to handle demanding environments, offering a close-off pressure rating of 200 psi and a safe working water pressure of 580 psi.

The VG1000 Series ball valve utilizes a specialized characterized insert to provide the flow performance of a globe valve with the efficiency of a ball valve. This model is "valve only" and is fully compatible with M9000 and VA9000 series actuators. With a maximum water temperature of 284?F and the ability to handle 15 psi saturated steam when used with a thermal spacer, it is a versatile choice for mechanical contractors looking for long-term reliability and ANSI Class IV leakage protection.

Key Benefits

• Stainless steel ball and stem provide superior corrosion resistance and longevity compared to standard plated brass.
• Equal percentage flow characteristic ensures linear heat output and stable room temperature control.
• High 29.2 Cv rating allows for high flow rates with minimal pressure drop in 1-1/4 inch piping.
• Blowout-proof stem and EPDM dual O-rings provide 200,000 cycles of leak-free operation.
• Universal mounting supports easy field integration with spring return or non-spring return electric actuators.

Common Questions

Is the VG1245DR compatible with steam applications?
Yes, because this model features stainless steel trim, it is rated for 15 psig saturated steam when installed with a proper thermal spacer. Brass trim models do not share this rating.

Which actuators can be used with this valve?
This valve is designed for use with Johnson Controls VA9104, VA9203, VA9208, and M9100 series electric actuators. It can be factory-mounted or field-installed using standard linkages.

What is the maximum glycol concentration allowed?
The VG1245DR is rated for water and water-glycol solutions with up to a 50% glycol concentration.
