Johnson Controls VG2431TM Valve

The Johnson Controls VG2431TM Valve is a 2-1/2 inch, two-way normally closed globe valve designed for precision water and steam regulation in commercial HVACR systems. Built with a rugged cast iron body and durable brass trim, this assembly utilizes an ANSI Class 125 flat-faced flange connection to ensure a secure, leak-resistant fit in high-demand domestic and industrial piping. With a flow coefficient of 54 Cv and a modified linear flow characteristic, the VG2431TM provides stable throttling and excellent rangeability for critical temperature and pressure control across hot water, chilled water, or 35 psig saturated steam applications.

This push-down-to-open (PDTO) model features a 3/8-inch threaded stem, making it fully compatible with various manual, electric, and pneumatic actuators, such as the MP8000 series. Engineered for a maximum allowable pressure of 175 psig at 150°F, it maintains tight close-off integrity (up to 0.1% leakage of max flow) to prevent energy loss. For veteran contractors, the VG2431TM globe valve represents a reliable standard for flanged iron valve replacement or new installations where consistent performance and field-serviceability are non-negotiable.

• Durable Construction: Features a high-tensile cast iron body and corrosion-resistant brass trim for extended service life in harsh HVAC environments.
• Precise Flow Modulation: The modified linear plug design ensures accurate flow regulation to maintain system setpoints.
• High Flow Capacity: Rated at 54 Cv for high-volume 2-1/2" piping requirements without excessive pressure drop.
• Standardized Fitment: ANSI Class 125 flanged connections allow for straightforward integration into existing hydronic or steam loops.

• What is the maximum temperature rating for this valve? The VG2431TM is rated for fluid temperatures ranging from 35°F to 281°F (up to 35 psig saturated steam).
• Can this valve be used for steam applications? Yes, it is suitable for low-pressure steam up to 35 psig at 281°F when properly matched with a compatible actuator.
• Is the actuator included with this model? No, this is the valve body assembly only (VG2431TM); actuators must be selected separately based on system signal requirements.
