Nordfab FLN Flanged Back Pressure Valve comes with pre-drilled, loose FLN flanges at each end for ease of alignment and connection to other ducting components during installation. Nordfab FLN Flanged Back Pressure Valve is designed to prevent air circulating. Its primary function is to prevent the reverse flow of air within ductwork system. These valves are typically installed in ducts where airflow needs to be unidirectional, such as exhause vents or ventilation systems. Available in galvanised steel construction, ranging from 160 mm to 710 mm in diameter.
Nordfab flanged ductwork is typically used for larger diameters and used in high-pressure industrial ventilation systems where airtight connections are essential.
