Description
Overview
The Johnson Controls VG7441NT+3008E is a factory-assembled, 2-way normally closed valve and pneumatic actuator combination engineered for precise flow control in commercial HVAC hydronic systems. The cast bronze body with brass trim delivers long-lasting corrosion resistance, while the equal percentage flow characteristic ensures smooth, responsive modulation across the full stroke range.
Valve Features
- 2-way, normally closed (N/C) configuration
- 1″ NPT end connections for straightforward pipe installation
- 11.6 Cv flow coefficient for accurate sizing in medium-capacity applications
- Equal percentage flow characteristic for stable, linear control response
- Cast bronze body with brass trim for durability and corrosion resistance
Actuator Features
- Spring return, exposed pneumatic actuator (Model 3008E)
- 9–13 PSI spring range for reliable fail-safe positioning on air loss
- Normally closed operation — valve closes automatically on loss of pneumatic signal
- Exposed actuator design allows for easy field inspection and maintenance
Applications
- Commercial and industrial HVAC hydronic heating and cooling systems
- Air handling unit coil control
- Fan coil unit water flow regulation
- Pneumatically controlled building automation systems
