Micro-Stop Slow Closing Butterfly Check Valve

The butterfly check valve with slight resistance and slow closing can be used in the drain pipe of clean water, sewage, sea water and other media, which can not only prevent the backflow of the media, but also effectively limit the destructive water hammer to ensure the safety of the pipeline.It has the characteristics of novel structure, small volume, light weight, small fluid resistance, reliable seal, stable opening and closing, wear resistance, long service life, oil pressure and slow closing not affected by medium, and good energy saving effect.
