Johnson Controls VG7443CT Valve

The Johnson Controls VG7443CT Valve is a professional-grade 2-way normally closed globe valve engineered for precision fluid control in commercial HVACR systems. Built with a 1/2" NPT connection, this 0.73 Cv globe valve features an equal percentage flow characteristic, making it ideal for the accurate regulation of hot water, chilled water, or saturated steam up to 100 psig. The cast bronze body and stainless steel trim provide exceptional resistance to corrosion and wear, ensuring long-term reliability in demanding environments. Designed with a standard threaded stem and push-down-to-open (PDTO) action, the VG7443CT is compatible with a wide range of electric and pneumatic actuators, including the VA7800 and V-3000 series. This valve assembly is frequently utilized in fan coil units and small reheats where tight shut-off and high rangeability are required to maintain system efficiency and stabilize discharge temperatures.

• Enhanced Durability: The stainless steel trim offers superior protection against scaling and erosion compared to standard brass options.
• Precise Control: Features equal percentage flow for stable modulation and consistent performance under varying system pressures.
• Versatile Application: Rated for water and saturated steam, providing a flexible solution for diverse mechanical room requirements.
• Serviceable Design: Built for veteran technicians with an in-place valve repacking capability to minimize downtime during routine maintenance.

What is the maximum close-off pressure for the VG7443CT?
Close-off pressure is actuator-dependent, but this 1/2" assembly typically handles up to 308 psig when paired with high-torque electric actuators or 75 psig with specific pneumatic setups.

Is this valve suitable for steam applications?
Yes, the VG7443CT is rated for saturated steam up to 100 psig at 338°F (170°C). For steam use, always ensure the valve is piped with the stem in a horizontal position.

Can I use this valve with a proportional controller?
Absolutely. While the valve body itself is mechanical, it is designed for use with proportional (0-10 VDC or 4-20 mA) and floating actuators to achieve precise setpoint control.
