Johnson Controls VG7243NT+3008B Valve Assembly

The Johnson Controls VG7243NT+3008B is a professional-grade 1-inch globe valve assembly designed for precise modulation in high-demand HVACR systems. This 2-way normally open pneumatic valve features a robust cast bronze body and a high-capacity 11.6 Cv, ensuring optimal flow control for hot water, chilled water, or saturated steam up to 100 psig. Built for durability in the field, it utilizes stainless steel trim and a spring-loaded PTFE V-ring packing, which significantly extends the service life compared to standard brass configurations. The assembly is powered by an integrated V-3000-8012 exposed pneumatic actuator, operating on a 3-6 PSI spring range. This VG7000 series valve provides an equal percentage flow characteristic, delivering the stable performance necessary for modern building automation interfaces. Whether you are performing a new installation or a critical retrofit, the VG7243NT+3008B offers the reliability and ANSI Class 250 pressure rating required for commercial and industrial piping environments.

• Maximum Durability: Engineered with stainless steel stems and plugs for superior corrosion resistance and longevity in steam and water systems.
• Precise Modulation: Equal percentage flow characteristics provide smooth, predictable control across a wide range of demand.
• High Temperature Capability: Rated for fluid temperatures ranging from 35°F to 338°F, making it suitable for both cooling and high-pressure steam applications.
• Field Reliability: The V-3000 pneumatic actuator has an effective diaphragm area of 8 sq. in. and an exposed design for easy inspection.
• Standardized Fit: 1-inch NPT threaded connections and a compact globe design allow for straightforward installation in existing pipe runs.

What is the fail-safe position of this assembly?
This is a normally open (N.O.) assembly, meaning the valve returns to the fully open position upon loss of control air pressure via the internal spring return.

Can this valve be used for steam applications?
Yes, the stainless steel trim and specialized packing allow this valve to handle saturated steam up to 100 psig (338°F).

Is the actuator replaceable in the field?
The VG7000 series is designed with a standardized mounting collar, allowing the actuator to be easily serviced or swapped without removing the valve body from the line.
