Description
The Belimo B308B is a 1/2-inch, 3-way characterized control valve (CCV) engineered for precise flow regulation in hydronic heating and cooling systems. Featuring a brass-trimmed body and Belimo’s proven characterized ball design, this valve delivers accurate, repeatable flow control across its full operating range — making it an ideal choice for fan coil units, air handling units, and terminal unit applications.
Belimo’s characterized control valves are widely recognized in the commercial HVAC industry for their equal-percentage flow characteristic, which closely matches the heat transfer curve of coils and heat exchangers. This results in superior controllability and energy efficiency compared to traditional globe valves.
