Description
Johnson Controls VG7241CT+3008B Valve Assembly Overview
The Johnson Controls VG7241CT+3008B is a complete valve and actuator assembly engineered for precise flow control in commercial HVAC hydronic and pneumatic systems. Combining a two-way, normally open globe valve body with a spring return exposed pneumatic actuator, this assembly delivers reliable, fail-safe operation in heating and cooling coil applications.
Valve Body Features
- Configuration: 2-Way, Normally Open (NO)
- Connection: 1/2″ NPT threaded end connections
- Flow Coefficient: 0.73 Cv
- Flow Characteristic: Equal Percentage — provides precise, proportional flow control across the full stroke range
- Body Material: Cast Bronze — corrosion-resistant for long service life in hydronic systems
- Trim Material: Brass — durable and compatible with standard hydronic fluids
Pneumatic Actuator Features
- Actuator Type: Spring Return, Exposed Pneumatic Actuator (Model 3008B)
- Spring Range: 3–6 PSI — proportional control with pneumatic signal input
- Action: Spring return ensures fail-safe positioning upon loss of air signal
- Design: Exposed actuator style for easy field inspection and maintenance
Application & Benefits
- Ideal for pneumatically controlled HVAC air handling units, fan coil units, and hydronic coil applications
- Equal percentage flow characteristic optimizes system efficiency and temperature control stability
- Factory-assembled valve and actuator combination reduces installation time and ensures proper component matching
- Normally open configuration provides full flow on loss of control signal — suitable for heating coil fail-safe requirements
- Compact 1/2″ NPT size fits tight mechanical room and air handler piping configurations
