Description
The Johnson Controls VG7842ST is a 2-inch NPT, 3-way mixing globe valve engineered for precise hydronic flow control in commercial HVAC and building automation systems. Built with a cast bronze body and brass trim, this valve delivers long-lasting corrosion resistance and reliable performance in demanding water and glycol applications.
Key Features
- 3-way mixing configuration for blending or diverting hydronic fluid streams
- 2-inch NPT end connections for straightforward threaded installation
- 46.2 Cv flow coefficient for high-capacity flow performance
- Linear flow characteristic for proportional, stable control response
- Cast bronze body construction for superior corrosion resistance
- Brass trim components for durability and compatibility with hydronic media
- Standard threaded stem for compatibility with a wide range of Johnson Controls and third-party actuators
Construction & Design
The VG7842ST features a robust cast bronze body that withstands the rigors of continuous hydronic system operation. The standard threaded stem pairs with Johnson Controls VA, VB, and VC series actuators, making it a versatile choice for new installations and retrofit projects. The linear flow characteristic ensures a consistent, predictable relationship between valve position and flow rate, simplifying system commissioning and control loop tuning.
Typical Applications
- Hydronic heating and cooling coil control
- Chilled and hot water mixing loops
- Fan coil unit and air handling unit valve assemblies
- Building automation and energy management systems
- Commercial and industrial HVAC water distribution
