Precision control for critical research spaces

Control designed for critical environments

High-performance, variable air volume airflow control valves for fume hood intensive, high-level containment, and pharmaceutical manufacturing facilities.


  • 1-second speed of response
  • Valves maintain +/- 5% accuracy over the entire flow range
  • Mechanical pressure independence for precise airflow control when duct pressure fluctuates


  • Demand based ventilation reduces air change rates when monitor indicates air quality is meeting standards 
  • Usage based controls reduce face velocity when fume hoods are unoccupied
  • Decommissioning modes allow for improved energy management 
  • Accurate flow over turndown ranges up to 20:1 compared to the 3:1 ratio of traditional VAV terminal boxes


  • Seamless integration
  • Less testing, balancing, and adjusting as valves are factory configured
  • Mechanical design flexibility means valves do not require straight duct runs upstream or downstream
