Micro Resistance Slow Closing Butterfly Check Valve

    Micro resistance slow closing butterfly check valve is an advanced valve product mainly used at the outlet of water pumps in industrial water supply and sewage treatment plants to prevent backflow of media in the pipeline network and automatically eliminate destructive water hammer, ensuring the normal operation and safety of water pumps and pipelines. This type of valve has the characteristics of novel structure, small volume, light weight, low fluid resistance, reliable sealing, smooth opening and closing, wear resistance, and long service life Working principle The working principle of the micro resistance slow closing butterfly check valve is to smoothly push open the two valve discs through the thrust of the inlet medium. When the pressure of the inlet medium drops below the outlet pressure, the valve disc automatically closes under the action of the spring and medium reflux. However, due to the extended position of the piston rod, it cannot ful…
