Johnson Controls VG2231WN Valve

The Johnson Controls VG2231WN is a heavy-duty, 5-inch globe valve engineered for precision control in large-scale chilled water and hot water systems. This 2-way normally open valve features a robust cast iron body with ANSI Class 125 flat-faced flange connections, ensuring a secure fit in industrial piping headers. With a 240 Cv rating and a modified linear flow characteristic, it provides stable modulation and high-capacity throughput for HVAC hydronic control applications. The unit utilizes a 1/2-inch threaded stem with push down to close action, making it compatible with high-torque pneumatic actuators or electric actuators. The brass trim enhances durability against low-pressure steam and treated water, while the normally open flange valve configuration serves as a fail-safe in critical heating or cooling loops. Designed for reliability in demanding commercial environments, the VG2000 series remains a standard for contractors requiring precise flow regulation and long-term mechanical integrity.

• High-Flow Capacity: The 240 Cv rating allows for significant volume displacement in 5-inch line sizes without excessive pressure drops.
• Durable Construction: Cast iron body and brass trim provide the necessary rigidity for industrial HVAC operating pressures.
• Standardized Integration: ANSI Class 125 flanged ends ensure compatibility with existing piping infrastructures and standard gaskets.
• Reliable Stem Action: The 1/2-inch threaded stem ensures a positive mechanical connection to the actuator, reducing hysteresis.

What is the maximum fluid temperature for the VG2231WN?
This Johnson Controls valve is typically rated for water temperatures ranging from 35°F to 281°F and saturated steam up to 35 psig, depending on the packing material used.

Which actuators are compatible with this 5-inch flanged valve?
The VG2231WN is designed to work with Johnson Controls MP8000 pneumatic series or VA-9070 series electric actuators, provided the linkage can accommodate the 1/2-inch stem and required stroke length.

Can this valve be used for steam applications?
Yes, the brass trim and cast iron construction are suitable for low-pressure steam modulation, commonly found in AEO-optimized HVAC systems.
