Description
The Johnson Controls VG7842CS is a 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 reliable, long-lasting performance in demanding heating and cooling applications.
Key Features
- 3-way mixing configuration for blending or diverting fluid flow
- 1/2″ NPT end connections for straightforward installation
- 0.73 Cv flow coefficient with linear flow characteristic for accurate, proportional control
- Cast bronze body construction for excellent corrosion resistance and durability
- Brass trim components for reliable seating and long service life
- Slotted stem design for easy actuator coupling and field adjustment
- Small bonnet profile for installation in tight mechanical spaces
Application
The VG7842CS is designed for use in hydronic heating and cooling systems where precise mixing or diverting of water or glycol solutions is required. Its linear flow characteristic makes it ideal for use with proportional or floating actuators in building automation and energy management systems. The compact small bonnet design allows installation in confined mechanical rooms and air handling unit piping arrangements.
