Description
Johnson Controls VG1245AN Two-Way Ball Valve Overview
The Johnson Controls VG1245AN is a precision-engineered two-way ball valve designed for demanding HVAC hydronic and building automation applications. Featuring a forged brass body and stainless steel trim, this valve delivers exceptional durability, corrosion resistance, and long service life in commercial and industrial installations.
Key Features
- 1/2″ NPT end connections for straightforward pipe installation
- 11.7 Cv flow coefficient for reliable, predictable flow performance
- Two-way, equal percentage flow characteristic for precise modulating control
- Forged brass body construction for superior strength and pressure integrity
- Stainless steel trim for enhanced corrosion resistance and longevity
- Compatible with Johnson Controls and other industry-standard actuators
- Designed for use in heating, cooling, and process control systems
Equal Percentage Flow Characteristic
The equal percentage flow characteristic of the VG1245AN ensures that equal increments of valve stem travel produce equal percentage changes in flow. This makes the valve ideal for modulating control applications where precise, stable control is required across a wide range of operating conditions — a critical performance attribute in variable-flow hydronic systems.
Construction & Materials
- Body: Forged brass — high-strength, pressure-rated construction
- Trim: Stainless steel — resists corrosion and wear in fluid service
- End Connections: 1/2″ NPT (National Pipe Thread)
Typical Applications
- Commercial HVAC hydronic heating and cooling systems
- Building automation and energy management systems
- Fan coil units and air handling unit coil control
- Variable flow chilled and hot water distribution
- Process temperature and flow control
