Product overview

HH46/48/49H micro resistance slow closing butterfly check valve is used in the drainage pipeline of clear water, sewage, seawater and other media, which can not only prevent the backflow of media, but also effectively limit destructive water hammer and ensure the safety of pipeline. It has the characteristics of novel structure, small volume, light weight, small fluid resistance, reliable sealing, stable opening and closing, wear resistance, long service life, oil pressure and slow closing are not affected by media, and has good energy-saving effect.
