Our company manufactures manual airflow control valves—also known as manual dampers or airflow regulators—which serve as critical components in ventilation and air-conditioning systems for regulating duct airflow and balancing flow among branch lines. By manually adjusting the vane angle to alter the effective cross-sectional area of the duct, these valves enable airflow regulation, duct on/off control, and system balancing, and are widely used in building fresh-air and exhaust systems, air-conditioning networks, and industrial ventilation ductwork.
