Description
The Johnson Controls VG7441RT+823E00 is a factory-assembled 2-way, normally closed valve and pneumatic actuator combination engineered for reliable flow control in commercial HVAC hydronic systems. The assembly pairs a cast bronze valve body with brass trim with a spring return pneumatic actuator, delivering dependable, fail-safe operation in heating and cooling applications.
Valve Features
- 2-way, normally closed (NC) configuration for fail-safe shutoff
- 1-1/2″ NPT end connections for straightforward pipe installation
- 28.9 Cv flow coefficient for precise, high-capacity flow regulation
- Equal percentage flow characteristic for accurate modulating control across the full stroke range
- Cast bronze body construction for excellent corrosion resistance and durability
- Brass trim for long service life in hydronic water and glycol systems
Actuator Features
- Spring return pneumatic actuator (model 823E00) for automatic fail-safe positioning on air loss
- 9–13 PSI spring range for compatibility with standard pneumatic control systems
- Designed for direct mounting to the VG7441RT valve body as a complete, pre-assembled unit
Typical Applications
- Commercial HVAC air handling units (AHUs)
- Fan coil units and terminal equipment
- Chilled water and hot water coil control
- Pneumatically controlled building automation systems
Why Choose the VG7441RT+823E00
This pre-assembled valve and actuator combination from Johnson Controls eliminates field assembly time and ensures proper component matching right out of the box. The equal percentage flow characteristic provides stable, proportional control across varying system pressures, making it ideal for modulating applications in commercial buildings. The spring return actuator guarantees the valve returns to its normally closed position on air failure, providing a critical layer of system protection.
