The slow closing check valve is used in the water supply and drainage pipeline. They are installed at the outlet of the
pump to prevent backflow of the medium and eliminate destructive water hammer. It can effectively reduce the valve closing water hammer pressure and ensure the safe operation of the pipeline.
2.The slow-closing check valve has futures light disc, large opening, significant
power saving effect, low fluid resistance, novel water hammer elimination mechanism design, stable and reliable sealing performance, good wear resistance, long service life, stable operation.
