Description
The Johnson Controls VG7441ST is a heavy-duty, 2-way normally closed globe valve engineered for precise flow control in commercial HVAC hydronic systems. Built with a cast bronze body and brass trim, this valve delivers reliable, long-lasting performance in demanding heating and cooling applications.
Key Features
- 2-way, normally closed (N.C.) configuration ensures fail-safe shutoff when actuator power is removed
- 2″ NPT end connections for straightforward installation into standard piping systems
- 46.2 Cv flow coefficient provides high-capacity flow suited for larger hydronic circuits
- Equal percentage flow characteristic delivers precise, proportional control across the full valve stroke
- Cast bronze body with brass trim offers excellent corrosion resistance and durability
- Standard threaded stem design for compatibility with a wide range of Johnson Controls actuators
- Push-down-to-open (PDO) action provides predictable, consistent valve response
Construction & Design
The VG7441ST features a robust cast bronze body that resists corrosion in hydronic water systems, making it ideal for chilled water, hot water, and condenser water applications. The brass trim components complement the bronze body for a reliable, leak-resistant assembly. The standard threaded stem interfaces seamlessly with compatible Johnson Controls electric or pneumatic actuators.
Applications
- Commercial HVAC hydronic heating and cooling systems
- Air handling unit (AHU) coil control
- Fan coil unit (FCU) water flow regulation
- Chilled water and hot water distribution systems
- Building automation and energy management systems
