Description
The Johnson Controls VG7443ST is a heavy-duty 2-inch, 2-way normally closed globe valve engineered for precise flow control in commercial HVAC and hydronic systems. Built with a cast bronze body and stainless steel trim, this valve delivers long-lasting corrosion resistance and reliable performance in demanding heating and cooling applications.
Key Features
- 2-way, normally closed (NC) configuration ensures fail-safe shutoff when de-energized
- Equal percentage flow characteristic for accurate, proportional control across the full stroke range
- Push-down-to-open (PDTO) action for compatibility with a wide range of Johnson Controls and third-party actuators
- Standard threaded stem for easy actuator mounting and field replacement
- Cast bronze body provides excellent corrosion resistance for water and glycol service
