Johnson Controls VG2831YN Valve

The Johnson Controls VG2831YN is a heavy-duty 6-inch 3-way mixing globe valve engineered for precise temperature control in large-scale HVAC systems. Featuring a high flow capacity of 347 Cv, this valve is built with a rugged cast iron body and durable brass trim to withstand demanding hydronic and steam applications. Designed with an ANSI Class 125 flat-faced flange, it ensures a secure, leak-resistant connection to existing piping. The modified linear flow characteristic provides stable modulation, making it an ideal choice for mixing hot and chilled water or 50% glycol solutions. For technicians performing field retrofits, the 1/2-inch threaded stem allows for seamless integration with MP8000 series pneumatic actuators or compatible M9000 series electric actuators. This VG2000 series flanged valve is rated for a maximum static pressure of 175 psi and fluid temperatures up to 281°F, delivering reliable performance in high-capacity building automation circuits.

• High Volume Flow: 347 Cv rating supports significant fluid movement in 6-inch commercial piping systems.
• Exceptional Durability: Cast iron construction with brass trim ensures longevity in chilled water and saturated steam service (up to 35 psig).
• Precise Modulation: Modified linear flow characteristics prevent hunting and provide stable temperature control for mixing applications.
• Standardized Fit: ANSI Class 125 flanged ends meet industry standards for straightforward installation and bolt-up.
• Versatile Actuation: Compatible with a wide range of Johnson Controls pneumatic and electric actuators via the 1/2-inch threaded stem.
