Information About 003Z0781
The 003Z0781 is a Danfoss AB-QM ANSI pressure-independent balancing and control valve designed for HVAC hydronic systems. It combines flow regulation and dynamic differential pressure control in one valve assembly. The valve supports flow rates up to 55 GPM and has a 2-inch nominal size with external NPT connections. Its ductile iron body and integrated pressure regulator help maintain controlled flow as system pressure changes.
Key Features:
-
Pressure-Independent Control: Regulates flow despite changes in system differential pressure.
-
Integrated Balancing: Combines control and balancing functions in one valve.
-
2-Inch Valve Size: Designed for compatible 2-inch piping systems.
-
Maximum Flow Capacity: Supports flow rates up to 55 GPM.
-
NPT Threaded Connections: Uses external NPT connections for installation.
-
Ductile Iron Body: Constructed from EN-GJL-250 ductile iron.
-
Integrated Test Plugs: Includes test points for system measurement.
-
Differential Pressure Range: Operates within a specified 4–60 psi differential pressure range.
The 003Z0781 delivers the reliability and precision required for HVAC flow control and hydronic system balancing applications.
