Johnson Controls VG7251ET Valve

The Johnson Controls VG7251ET is a professional-grade 1/2 inch globe valve specifically engineered for regulating the flow of hot water, chilled water, and saturated steam in commercial HVACR systems. Built with a heavy-duty cast bronze body and 1/2" union globe connections, this 2-way normally open valve provides reliable performance under high-demand conditions. The 1.8 Cv equal percentage flow characteristic ensures precise linear control, making it ideal for proportional modulation in terminal units and reheat coils. Featuring brass trim and a standard threaded stem, this VG7000 series valve utilizes a push-down-to-close action (PDTC) for fail-safe integration. Designed for maximum durability, the assembly supports fluid temperatures ranging from 35?F to 284?F and is rated for ANSI Class 250 static pressure. Field contractors trust the VG7251ET for its high close-off capabilities and seamless compatibility with various pneumatic and electric actuators, ensuring tight shut-off and long-term system efficiency without frequent maintenance overhead.

• Precision Modulation: The 1.8 Cv equal percentage plug design facilitates accurate temperature control in hydronic and steam loops.
• Rugged Construction: Cast bronze body and brass trim provide superior corrosion resistance and longevity in standard HVAC applications.
• High Pressure Rating: Rated for ANSI Class 250, offering robust performance in high-rise and industrial piping systems.
• Versatile Media Compatibility: Suitable for water, 50/50 glycol solutions, and saturated steam up to 38 psig.
• Simplified Installation: The 1/2" union globe connection allows for easy removal and servicing within tight mechanical spaces.

What is the primary application for the VG7251ET?
This valve is most frequently used in fan coil units, unit ventilators, and baseboard radiation systems where precise terminal control of water or steam is required.

Is this valve compatible with pneumatic actuators?
Yes, the VG7251ET features a standard threaded stem that integrates with V-3000 pneumatic actuators as well as VA-715x and VA-720x series electric actuators.

Can this valve be mounted in any orientation?
It is highly recommended to mount the valve in an upright position. Ensure the flow arrow on the bronze body matches the system flow direction so the plug seats against the flow for optimal close-off.
