Ductile Iron Cast Steel Micro Resistance Slow Closing Butterfly Type Check Valve

Product introduction:

HH46X series micro resistance slow closing butterfly type check valve are mainly composed of valve bodies, valve discs, buffer devices, and micro regulating valves. They can be used on industrial water supply and drainage pipelines for clean water, sewage, seawater, and other media, as well as at the outlet of sewage treatment plant water pumps. They can prevent the backflow of media and effectively limit destructive water hammer, ensuring the safety of pipeline use. It has the characteristics of novel structure, small volume, light weight, low fluid resistance, reliable sealing, smooth opening and closing, wear resistance, long service life, improper oil pressure and slow closing medium influence, and effective energy-saving effect

Product technical parameter:

Product features:

1. Small in size, lightweight, and with a structural length only about one-third of that of a swing 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 cushioning, smooth opening and closing, no vibration, no noise.
5. Compared to old-fashioned check valves, it has a smaller flow resistance and significant energy-saving effect.
