Product Details
This series of valves are used as bi-directional open-close switches and flow regulators in ventilation and dust removal pipeline systems.
The valves feature simple structures and reliable performance; they can be installed in either direction without considering the restraint of medium flow direction.
The valves have segmented shafts and thin butterfly plates, with relatively small flow resistance. Based on different requirements for the leakage rate and working
temperature, two sealing structures are optional.
