Johnson Controls VG7441GT+3008E Valve Assembly Overview
The Johnson Controls VG7441GT+3008E is a complete valve and actuator assembly engineered for precise flow control in commercial HVAC hydronic and pneumatic control systems. This 2-way, normally closed configuration ensures fail-safe operation, automatically closing upon loss of control signal or air pressure — a critical safety feature for heating and cooling coil applications.
Valve Body & Trim
- 2-way, normally closed (NC) configuration
- 1/2″ NPT end connections for straightforward installation
- 4.6 Cv flow coefficient for accurate flow capacity sizing
- Equal percentage flow characteristic for stable, linear control response across the operating range
- Cast bronze body for excellent corrosion resistance and long service life
- Brass trim for durability and compatibility with hydronic media
Pneumatic Actuator
- Spring return, exposed pneumatic actuator design
- 9–13 PSI spring range for reliable, consistent actuation
- Spring return action provides fail-safe normally closed position on loss of pneumatic signal
- Exposed actuator design allows for easy field inspection and maintenance
Applications
- Commercial HVAC heating and cooling coil control
- Pneumatic building automation and control systems
- Hydronic piping systems requiring precise 2-way flow modulation
- Fan coil units, air handling units, and terminal unit applications
Why Choose the VG7441GT+3008E?
The factory-assembled VG7441GT+3008E combines Johnson Controls’ proven VG7000 series valve body with a matched pneumatic actuator, eliminating field assembly errors and ensuring optimal performance. The equal percentage flow characteristic delivers superior controllability at partial load conditions — the most common operating state in HVAC systems. The cast bronze body and brass trim construction provide lasting reliability in demanding commercial environments.
