Johnson Controls VG7243GT Valve

The Johnson Controls VG7243GT is a heavy-duty 1/2 inch NPT Globe Valve engineered for precise control of water and steam in demanding HVAC systems. Featuring a 2-way normally open configuration with Push-Down-to-Close (PDTC) action, this valve utilizes an equal percentage flow characteristic to ensure stable modulating control across varying load conditions. The cast bronze body is paired with stainless steel trim and a stainless steel stem, providing superior resistance to corrosion and wear compared to standard brass components. With a 4.6 Cv flow coefficient, the VG7000 series is designed for seamless integration with VA series electric actuators or pneumatic actuators, making it a reliable choice for chilled water systems, hot water applications, and low-pressure steam service up to 38 psig. The standard threaded stem allows for straightforward field installation and maintenance, ensuring long-term seat tightness and operational efficiency in high-cycle environments.

• Enhanced Durability: The stainless steel trim prevents premature pitting and ensures a tight seal in aggressive fluid environments.
• Precise Control: The equal percentage flow curve provides linear heat output for better temperature stability and reduced hunting.
• Versatile Media Handling: Rated for a wide temperature range, making it suitable for both hydronic heating and cooling coil applications.
• Standardized Fitment: The 1/2" NPT connection and VG7000 series footprint allow for drop-in replacement with existing Johnson Controls hardware.

What actuators are compatible with the VG7243GT?
This valve is designed to work with Johnson Controls VA-7150, VA-7200, and VA-4233 series actuators, as well as pneumatic options using the standard bonnet mounting.

Can this valve be used for steam applications?
Yes, the VG7243GT is rated for saturated steam up to 38 psig, provided the appropriate high-temperature packing and actuator combinations are utilized.

What is the benefit of the Stainless Steel trim over brass?
The stainless steel internal assembly offers significantly higher resistance to cavitation and erosion, extending the service life of the valve seat and plug in high-velocity systems.
