Description
The Johnson Controls VG7441ST+823E00 is a factory-assembled, 2-way normally closed control valve engineered for precision flow regulation in commercial HVAC and building automation systems. The assembly pairs a cast bronze body valve with a spring-return pneumatic actuator, delivering reliable, fail-safe operation in heating and cooling applications.
Valve Features
- 2-way, normally closed (NC) configuration for fail-safe shutoff
- 2″ NPT end connections for straightforward pipe installation
- Flow coefficient (Cv) of 46.2 for high-capacity flow control
- Equal percentage flow characteristic for precise, stable modulation
- Cast bronze body construction for corrosion resistance and durability
- Brass trim components for long service life
Pneumatic Actuator Features
- Model 823E00 spring-return pneumatic actuator
- 9–13 PSI spring range for direct-acting pneumatic control
- Spring-return design ensures fail-safe, normally closed position on loss of air pressure
- Compatible with standard pneumatic control systems
Applications
- Commercial HVAC hydronic heating and cooling coil control
- Building automation and direct digital control (DDC) systems
- Air handling unit (AHU) coil valve control
- Fan coil unit (FCU) water flow regulation
- Chilled water and hot water distribution systems
