Danfoss AB-QM 4.0 DN 15 Pressure Indepenent Balancing & Control Valve with Test Plugs - External Thread - 003Z8201

Danfoss AB-QM Datasheet

The Danfoss AB-QM is a Pressure Independent Control Valve (PICV) that combines high accuracy and durability with market leading user-friendliness. The design of the AB-QM is fully geared towards making your project run on time and on budget while delivering the most efficient HVAC system.

Pressure independent valves are control valves with an automatic balancing function. An in-built pressure controller keeps a constant differential pressure over the control valve, ensuring full authority and automatic flow limitation. By combining two functions in one, control and automatic hydronic balance, Danfoss PICVs provide a cost-efficient solution for the challenges faced by forward-looking designers of HVAC systems. AB-QM can be used also in Industrial refrigeration systems.

The Danfoss AB-QM delivers the lowest total cost of ownership because:

• Precise flow limitation ensures always the right flow at the right time, ensuring minimized pumping energy
• Full range from DN 15 to DN 250 for flows up to 500 m3 /h
• Available with internal and external thread for universal applicability
• Danfoss’ durability test ensures the AB-QM has best-in-class resistance to scaling and clogging
• Easy troubleshooting because of the always visible setting and the ability to measure flow through test plugs
• Minimum hysteresis for stable and precise temperature control
• Future-ready with a range of smart actuators, ready for data driven and optimized HVAC 4.0
