Pressure Independent Balancing Control Valves

RZBM is a complete line of automatic balancing and control valves that provide flow limitation with complete control over hydronic regulation. PIBCV valves with automatic balancing provide stable flow regulation regardless of system pressure fluctuations, and all valves have an adjustable flow limitation set point. The PIBCV control valve further regulates the water/glycol flow from close-off to the maximum flow limit setting. Temperature control of chillers, air handling units, heat exchangers, and terminal units such as fan coils, induction units, and radiant panels are typical applications.
