570109-378 Armstrong CBV-4FS Flanged Circuit Balancing Valve. Armstrong circuit balancing valves (cbvs) have been used for many years as an effective means of ensuring occupant comfort in buildings. Heating and chilled water systems are designed to deliver the correct amount of heated or chilled fluid to every part of a building’s hvac system. However, this ‘design flow’ is frequently not achieved without the use of balancing valves. 


For decades, Armstrong has been supplying top-quality balancing valves to the global hvac industry. Our designs have always incorporated a multi-turn, ‘Y’ pattern, globe-style valve. Simply put, we provide the best valve design for optimizing both balancing control and Cv. 

For applications ranging from 1⁄2" to 12" sizes, Armstrong cbvs have been used reliably in tens of thousands of installations around the world. Our industry-leading design innovations have made Armstrong cbvs a trusted brand of balancing valves for balancing contractors and engineers alike.
