This Danfoss pressure independent control valve (PICV) is designed for regulating flow within hydronic heating and cooling systems. It features a 1-inch nominal pipe size connection and is capable of handling flow rates ranging from 2.4 to 12 gallons per minute (gpm). The AB-QM model ensures precise flow control, contributing to the optimization of system performance by maintaining the balance between pressure fluctuations and desired flow rates. This valve is typically used in commercial HVAC applications to improve system efficiency and comfort levels.
