The square constant air volume regulating valve is a mechanically automatic control device with a servo mechanism, requiring no external power supply. It is applicable to air supply and exhaust duct systems that require constant air volume control. Its regulating performance is independent of air pressure.
This series of square constant air volume regulating valves features complete specifications. Standard models are classified by B×H dimensions, and the valve body material is optional between galvanized steel sheet and stainless steel.
