Description
The Belimo G340B-N is a heavy-duty, 3-way globe valve engineered for precision flow control in commercial and industrial HVAC hydronic systems. Built with a durable bronze body and brass trim, this valve delivers reliable mixing or diverting operation across a wide range of heating and cooling applications.
Key Features
- 3-way configuration supports both mixing and diverting applications
- 1-1/2″ NPT end connections for straightforward installation
- 28 Cv flow coefficient for high-capacity flow performance
- Linear flow characteristic for accurate, proportional control
- Bronze body construction for corrosion resistance and long service life
- Brass trim for compatibility with hydronic water systems
- Designed to pair with Belimo actuators for automated control
Application
The G340B-N is ideal for use in chilled water, hot water, and condenser water systems where precise temperature or flow regulation is required. Its 3-way design allows it to function as either a mixing valve — combining two inlet streams into one outlet — or a diverting valve, splitting a single inlet flow to two outlets. The linear flow characteristic ensures consistent, predictable control response when paired with a compatible Belimo actuator.
