Johnson Controls VG2231YN Valve

The Johnson Controls VG2231YN is a heavy-duty 6-inch globe valve engineered for precision control in large-scale hydronic systems. Designed for 2-way normally open operation, this valve features a Cast Iron body with ANSI Class 125 flat-faced flanges, ensuring a secure and leak-resistant fit in industrial piping networks. The 350 Cv flow coefficient and modified linear flow characteristic provide stable modulation, making it an ideal choice for chilled water or hot water applications requiring high flow capacity. Its push-down-to-close action is paired with a durable brass trim and a 1/2-inch threaded stem, allowing for seamless integration with high-torque electric or pneumatic actuators. Whether you are performing a field replacement or a new system install, the VG2231YN delivers the mechanical reliability required for tight shut-off and long-term throttling performance in demanding HVACR environments.

• High Flow Capacity: A 350 Cv rating provides minimal pressure drop across the 6-inch port for optimized pump efficiency.
• Industrial Durability: The Cast Iron body and brass internal trim withstand the rigors of commercial heating and cooling cycles.
• Standardized Mounting: ANSI Class 125 flanges and a 1/2-inch threaded stem ensure compatibility with standard HVAC control valves and actuators.
• Modified Linear Performance: Precisely engineered for stable flow control, reducing hunting in large-diameter hydronic loops.

Common Questions:

What is the maximum fluid temperature for the VG2231YN? This valve is typically rated for water temperatures ranging from 35°F to 281°F, depending on the specific actuator and packing assembly used.

Can I use this globe valve for steam applications? The VG2231YN is primarily designed for water and glycol solutions; always verify trim compatibility if intended for low-pressure steam service.

Which actuators are compatible with this 6-inch valve? It is designed to work with high-force Johnson Controls series actuators capable of handling the 1/2-inch stem and the pressure requirements of a normally open globe valve.
