Johnson Controls VG7251GT Valve

The Johnson Controls VG7251GT is a high-performance 1/2 inch 2-way normally open globe valve designed for precision control of hot water, chilled water, and steam in commercial HVAC systems. Built with a rugged cast bronze body and brass trim, this valve ensures long-term durability and resistance to corrosion in demanding mechanical environments. Featuring a 4.6 Cv and an equal percentage flow characteristic, it provides stable and accurate modulation, which is essential for maintaining optimal coil performance and system efficiency. The union globe connection simplifies installation and field service, making it a go-to choice for contractors managing VG7000 Series valve assemblies.

This valve utilizes a standard threaded stem and a push-down-to-close action, ensuring a tight close-off when paired with compatible pneunmatic or electric actuators. With an ANSI Class 250 static pressure rating, the VG7251GT valve body handles fluid temperatures ranging from 35°F to 284°F and saturated steam up to 38 psig. Whether you are performing a Johnson Controls valve replacement or a new system integration, this NPT series globe valve provides the reliability required for mission-critical environmental control.

• Precise Flow Modulation: The equal percentage flow characteristic allows for superior control over a wide range of heating and cooling loads.
• Durable Construction: The cast bronze body and brass trim provide industrial-grade protection against mineral buildup and oxidation.
• High Pressure Performance: Rated for ANSI Class 250, this valve is suitable for high-pressure water and steam applications.
• Ease of Service: The union connection design allows for quick removal and maintenance without cutting into the piping system.

• Is this valve compatible with pneumatic actuators? Yes, the VG7251GT is frequently paired with V-3000 series pneumatic actuators, though it also supports VA-715x and VA-7000 series electric actuators.
• What is the maximum steam pressure rating? This valve is rated for saturated steam up to 38 psig, making it ideal for low-pressure steam heating systems.
• Can the valve packing be serviced in the field? Yes, the VG7000 series design allows for in-place valve repacking, reducing downtime during routine maintenance.
