AB-QM™ Support Hub

AB-QM™ is a pressure independent balancing control valve (PIBCV or PICV) that controls hydronic system flow, to match the load, continuously balancing the system, under pressure changes. The three-in-one design provides:

• control
• balance
• flow limitation

The unique design incorporates a pressure independent control & a differential pressure regulator, that instantly absorbs changing building pressures, constantly balancing, & establishing a high flow limitation through the valve. 

AB-QM™ valves can be used in a variety of heating and cooling applications, to help balance and optimize the hydronic system, but it's typically found in:

• Hot / cold water coils
• Variable air volume units (VAV)
• Sensible-cooling terminal units
• Fan coil units
• Air handling units (AHU)

AB-QM™ is one of the simplest valves to set & size, as the valve is selected based on flow requirements & piping size, eliminating the need for time consuming Cv calculations & complicated algorithms.
