Application
The B350L is designed for use in commercial HVAC hydronic systems where precise flow control of chilled or hot water is required. Its glycol compatibility — up to 60% solution — makes it well-suited for freeze-protection applications in cold climates or process cooling systems. The modified linear flow characteristic ensures stable control performance when paired with a compatible Belimo actuator.
