BUTTERFLY SLOW CLOSING TILTING DISC CHECK VALVE
This butterfly non-slam check valve , It can be used in the drainage pipes of clear water, sewage, seawater and other media, which can not only prevent the backflow of the medium, but also effectively limit the destructive water hammer and ensure the safety of the pipeline. The micro-resistance slow-closing butterfly check valve has the advantages of novel structure, small size, 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 the medium. Good energy-saving effect and so on. These series micro-resistance slow-closing butterfly check valve has been widely used in major industries, urban construction and other industries, and the response is good.
