H77 Single-Disc Butterfly Tilting Check Valve is a high-efficiency unidirectional check valve that combines the advantages of both butterfly and swing check valves. The disc can flexibly tilt open when fluid passes through, and quickly closes during reverse flow, ensuring one-way flow of the medium and effectively preventing backflow.
H77 Tilting Swing Check Valve has a disc that can be either vertical or tilted, similar to the structure of a triple-offset butterfly valve. Flanged butterfly check valves are often used in large-diameter pipelines, which can exceed DN2000, and employ a slow-closing structure.
