TAIL PIECE DANFOSS EXT. THREAD DN 25

The AB-QM control valve was the first of its kind for HVAC systems. It is a control valve with automatic flow limitation and an integrated differential pressure regulator across the valve. The result is a high-performance control valve with the unique 100% authority. The design flow rate can be easily set within the 20–100% range. Simply setting the design flow rate replaces traditional commissioning procedures, enables much more precise control, and eliminates the need for Kv calculations in system design. Easy setting and sizing. The valve’s 100% authority enhances control quality and accuracy even at low flow rates, improving building comfort while delivering energy savings. Perfect controllability—because flow is always right at the right time, AB-QM ensures the correct flow at the correct time while optimizing the chiller. Additionally, actuators require less adjustment, extending their service life and reducing overall costs. This product description is an automated translation of the original Finnish description.
