CONTROL VALVE DANFOSS 1/2 AB-QM HF

The Danfoss AB-QM control valve was the first of its kind for HVAC systems. It is a control valve featuring automatic flow limitation and an integrated differential pressure regulator across the valve. The result is a high-performance control valve with unique 100% authority. The design flow rate can be easily set within a 20-100% range. Setting only the design flow rate replaces traditional commissioning processes, enables much more precise control, and eliminates the need for Kv calculations in system design.
