The ABV Automatic Balancing Valves maintain a constant airflow volume in HVAC applications. The engineered damper blade is calibrated to automatically adjust to varying pressures using physics ( not electricity ) giving the ABV true pressure independence.
Airflow Balancing Valves have been very popular in Europe for several years, and we are proud to be the first to build this type of product in the United States and the first to design the product specifically to meet the needs of American applications.
ABV Sizes Available • Airflow Range
Nominal 4" Diameter • 25 to 130 CFM
Nominal 5" Diameter • 25 to 130 CFM
Nominal 6" Diameter • 50 to 275 CFM
Note: Airflow range determined through +/- 10% of average airflow over 0.2" to 2" W.C.
OEM Applications such as chilled beams, Fan Coil Units, PTAC units, centralized fan systems, fresh/make-up air
systems, and
HRV/ERV’s.
Any HVAC applications with a static pressure between 0.2
and 2.0 inches w.c.
- Traditional Balancing can’t respond
to system changes - Too much ventilation
= wasted energy - Too little ventilation
= bad air quality
- As heat rises in buildings during winter months the ventilation rates can more than double from “Stack Effect”
- The excess air forces the fans to freewheel
- Stale air from lower floors can contaminate upper floors
- Result:
Bad Air Quality & Wasted Energy
- Use of the ABV creates an “auto balancing” system
- An auto balanced system assures correct ventilation rates regardless of system changes
- Autobalancing = less energy $ and better IAQ
