Description
The Johnson Controls VG7241ET+7152G is a pre-assembled valve and actuator combination engineered for precise hydronic flow control in commercial HVAC systems. The assembly pairs a cast bronze globe valve body with brass trim with a non-spring return proportional actuator, delivering reliable modulating performance in heating and cooling applications.
Valve Features
- Valve size: 1/2″ NPT end connections
- Flow configuration: 2-way (two-position) design
- Flow characteristic: Equal percentage for stable, linear control response
- Flow coefficient (Cv): 1.8
- Body material: Cast bronze for superior corrosion resistance and durability
- Trim material: Brass for long service life and compatibility with hydronic media
Actuator Features
- Actuator model: 7152G non-spring return proportional actuator
- Control signal: 0–10 Vdc proportional input for smooth, stepless modulation
- Supply voltage: 24 Vac
- Return type: Non-spring return — actuator holds last position on power loss
- Operation: Proportional control for precise flow regulation in response to building automation system (BAS) or DDC controller output
Application Highlights
- Ideal for fan coil units, air handling units, and terminal unit hydronic coil control
- Compatible with building automation systems outputting 0–10 Vdc analog signals
- Equal percentage flow characteristic ensures stable loop performance across varying load conditions
- Factory-assembled combination simplifies installation and reduces field wiring time
- Cast bronze body suitable for chilled water, hot water, and glycol hydronic systems
