Johnson Controls VG2231UL Valve

The Johnson Controls VG2231UL is a heavy-duty 3-inch globe valve designed for precise flow control in commercial HVAC systems, specifically for chilled water, hot water, and steam applications up to 15 psig. Built with a rugged cast iron body and brass trim, this 2-way normally open valve features an ANSI Class 125 flat-faced flange connection, ensuring a reliable seal in high-pressure environments. With an 83 Cv rating and modified linear flow characteristic, it provides stable modulation for air handling units and heat exchangers. The 3/8-inch threaded stem utilizes a push-down-to-close action, making it compatible with high-torque electric or pneumatic actuators. This industrial-grade flanged globe valve is engineered for longevity in demanding mechanical rooms where accurate performance and thermal stability are critical for system efficiency.

• Durable Construction: The cast iron body and brass internal components provide superior resistance to wear in varied hydronic environments.
• Precise Flow Control: A modified linear flow profile ensures stable temperature regulation and reduces hunting in automated control loops.
• Standardized Integration: The ANSI Class 125 flanged interface allows for straightforward installation into existing iron piping systems.
• High Flow Capacity: An 83 Cv rating supports high-volume fluid transfer with minimal pressure drop across the valve body.

What is the maximum fluid temperature for the VG2231UL?
This valve is typically rated for water temperatures between 35°F and 281°F and low-pressure steam up to 15 psig, depending on the packing material used.

Which actuators are compatible with this 3-inch globe valve?
The 3/8-inch threaded stem is designed to interface with Johnson Controls MP8000 series pneumatic actuators or VA series electric actuators that meet the required close-off force.

Can this valve be used for steam applications?
Yes, the VG2231UL is suitable for saturated steam applications up to 15 psig when paired with the appropriate high-temperature packing and actuator setup.
