Description
The Johnson Controls VG7441PT is a 2-way, normally closed globe valve engineered for precise flow control in commercial HVAC hydronic and steam systems. Featuring a cast bronze body with brass trim, this valve delivers reliable, long-lasting performance in demanding building automation and mechanical system applications.
Key Features
- 2-way, normally closed (NC) configuration for fail-safe operation
- 1-1/4″ NPT end connections for straightforward pipe installation
- 18.5 Cv flow coefficient for accurate flow capacity sizing
- Equal percentage flow characteristic for precise modulating control across the full stroke range
- Cast bronze body with brass trim for corrosion resistance and durability
- Standard threaded stem design for compatibility with a wide range of Johnson Controls actuators
- Push-down-to-open (PDO) stem action for intuitive actuator pairing
Construction & Design
The VG7441PT globe valve body is constructed from cast bronze, providing excellent resistance to corrosion in hydronic heating, cooling, and steam applications. The brass-trimmed internals ensure smooth, reliable operation over extended service life. The standard threaded stem interface allows for easy pairing with compatible Johnson Controls electric or pneumatic actuators.
Flow Characteristics
The equal percentage flow characteristic of the VG7441PT provides inherently stable control across a wide range of system pressures and flow rates. This makes it an ideal choice for variable flow hydronic systems, coil control, and other HVAC applications where precise modulation is required.
Applications
- Hydronic heating and cooling coil control
- Building automation and energy management systems
- Commercial HVAC air handling units
- Fan coil unit water flow control
- Steam and hot water distribution systems
