Description
The Johnson Controls VG7841ES is a precision-engineered 3-way mixing globe valve designed for hydronic heating and cooling systems where reliable flow control is critical. Built with a cast bronze body and brass trim, this valve delivers long-lasting corrosion resistance and durability in commercial HVAC applications.
Key Features
- Globe-style, 3-way mixing configuration for blending or diverting fluid streams
- 1/2″ NPT end connections for straightforward pipe installation
- 1.8 Cv flow coefficient for accurate flow capacity sizing
- Equal percentage flow characteristic for precise, stable control across the full valve stroke
- Cast bronze body construction for superior corrosion resistance and long service life
