The HH49X micro resistance slow closing butterfly check valve is mainly used in the supply and drainage pipelines of clean water,source water,sewage,seawater and other media.It is installed at the outlet of the water pump to cut off the backflow of the medium and eliminate the destructive water hammer caused by atomic energy,protecting the safe operation of the pipeline and water pump.
main features
1.Small in size,light in weight,and with a structural length only about one-third of that of a rotary check valve.
2.The slow closing system has excellent performance and is not affected by the medium in the pipeline.The valve disc closes quickly first and then slowly,which can prevent destructive water hammer.
3.Rubber soft seal,good sealing performance,wear-resistant,and long service life.
4.Rubber buffer,smooth opening and closing,no vibration,no noise.
5.Compared to traditional check valves,it has lower flow resistance and significant energy-saving effects.
