Johnson Controls VG7441NT Valve

The Johnson Controls VG7441NT is a heavy-duty 1-inch NPT globe valve engineered for precision control in commercial HVAC systems. This 2-way normally closed valve features a robust cast bronze body and high-grade brass trim, ensuring reliable performance in both hot water and chilled water applications. With an 11.6 Cv rating and an equal percentage flow characteristic, the VG7441NT provides excellent modulating control, preventing hunting in the loop even at low demand. The standard threaded stem is designed for push-down-to-open action, making it compatible with a wide range of Johnson Controls pneumatic and electric actuators. Built to withstand fluid temperatures between 35°F and 281°F and a maximum static pressure of 400 psig, this bronze globe valve is a staple for contractors requiring a durable proportional control valve for demanding hydronic environments.

Key Benefits for Technicians:

• Equal Percentage Flow: Provides stable control over a wide range of loads, essential for HVAC hydronic systems.
• Normally Closed Configuration: Defaults to the shut position for fail-safe operation in heating or cooling loops.
• High Flow Capacity: The 11.6 Cv rating allows for efficient fluid handling in 1-inch piping systems.
• Durable Construction: The cast bronze body and brass internals resist corrosion and mechanical wear in high-cycle applications.
• Standardized Mounting: Features a push down to open stem that integrates seamlessly with VA series actuators.
