Round bi-flow control valves with actuator, opened when under current and with spring return
Minimal and maximal air volumes can be adjusted on site
KRK-A-TP 160, 25 m³/h / 210 m³/h
Explanation
KRK-A-TP = Type of regulating damper
160 = Duct size
25 m³/h = Minimal airflow when valve is closed
210 m³/h = Maximal airflow when valve is open
