Johnson Controls VG7251NT Valve

The Johnson Controls VG7251NT is a heavy-duty 1-inch globe valve engineered for precision fluid control in commercial HVAC systems. This 2-way normally open valve features a cast bronze body and brass trim, ensuring reliable performance in hot water, chilled water, or 15 psig saturated steam applications. With an 11.6 Cv rating and equal percentage flow characteristics, the VG7251NT provides stable modulating control, preventing hunting in high-demand loops. Designed with a union globe configuration and a standard threaded stem, it allows for seamless integration with pneumatic or electric actuators. The push-down-to-close action ensures a tight seal and consistent shut-off under pressure. For contractors replacing older VG7000 series valves, this unit maintains the industry-standard interchangeability and rugged durability required for hydronic system balancing and building automation upgrades.

• Optimized Flow Control: The 11.6 Cv equal percentage plug provides superior throttling for accurate temperature regulation.
• Durable Construction: Built with a cast bronze body to resist corrosion and withstand high-pressure environments.
• Versatile Application: Suitable for both water and steam systems, making it a versatile choice for mechanical rooms.
• Standardized Threading: The threaded stem design facilitates quick field-fitting with compatible Johnson Controls actuators.
