The Accutrol AVR4000 is an electronically pressure independent AccuValve®. It takes the revolutionary design of the exceptionally low pressure drop AccuValve and builds temperature and airflow control into the electronics. The AVR4000 is designed for critical airflow tracking control in research and healthcare spaces where standard speed actuation and precise airflow measurement and room temperature control is required. The integral native BACnet® MS/TP allows direct communication to the Building Automation System (BAS) where desired.
