Danfoss 003Z0781 2" AB-QM Pressure Independent Control Valve 22-55 GPM

The Danfoss 003Z0781 AB-QM is a 2-inch pressure independent control valve (PICV) designed for hydronic heating and cooling systems. This advanced valve combines a pressure independent balancing valve, control valve, and flow limiter in a single unit, simplifying installation and ensuring optimal system performance.

Key Features:

• Flow range of 22-55 gallons per minute for mid-sized commercial applications
• 2-inch NPT connection size for standard piping integration
• Pressure independent operation maintains constant flow regardless of pressure fluctuations
• Integrated balancing and control functionality eliminates need for separate valves
• Compact design reduces installation time and labor costs
• High-quality brass construction for long-term durability
• Compatible with Danfoss actuators for precise temperature control

The AB-QM series is ideal for commercial HVAC applications including fan coil units, chilled beams, air handling units, and radiant heating/cooling systems. This PICV ensures accurate flow control and energy-efficient operation by automatically compensating for pressure variations in the system, making it an excellent choice for modern building automation systems.
