Danfoss 003Z1333 Valve 318172-701 What systems use the A-4400-607The Danfoss 003Z1333 is a high performance Pressure Independent Control Valve (PICV) from the AB QM series, specifically engineered for 3 4" hydronic piping systems. This valve eliminates the need for complex Cv calculations by integrating a differential pressure controller directly into the assembly, ensuring 100% valve authority regardless of system pressure fluctuations. Designed with a robust CW 617N brass body, it handles an adjustable flow range
