Product Description:

Main Features of Swing Check Valve

  • Simple structure: the swing check valve consists of valve body, valve disc and valve stem, the structure is simple and compact, easy to install and maintain.
  • Strong corrosion resistance: the valve body and valve disc are usually used in corrosion resistant materials, such as stainless steel, alloy steel, etc., which can adapt to a variety of corrosive media.
  • Good negative pressure sealing performance: the valve disc adopts the spiral structure, rotating movement, can maintain a good sealing performance in the negative pressure environment, to avoid reflux.
  • Low flow resistance: because the gap between the disc and the seat is relatively small, the resistance of the valve is low, which can effectively reduce the pressure loss.
  • Flexible opening and closing: the rotary check valve is opened and closed by rotating the valve disc, with flexible operation, quick response, and no water shock phenomenon.
  • Wide range of application: swing check valve is suitable for liquid and gas media, can be widely used in urban water supply and drainage, heating, chemical, petroleum, pharmaceutical, food and other industries pipeline system. The valve can be automatically opened and closed with medium force, and quickly closed with a heavy hammer, and slowly closed with a hydraulic cylinder to prevent pipe vibration. The valve can also be manually opened and locked in the open position to overweld the sealing surface of the valve seat and disc, to improve the erosion resistance and prolong the service life of the valve Large diameter check valve is designed with hydraulic damping cylinder to prevent the valve disc from closing too fast and hitting the valve seat, damaging the valve or lead, and starting the pipe vibration
