      Detailed description

      Brief introduction of plug valve series

      I. Overview Plug valve refers to a valve in which the closing member (plug) rotates around the center line of the valve body to open and close.
      The plug valve is mainly used in the pipeline to cut off, distribute and change the direction of medium flow. Plug valves are the earliest valves used in history. Due to its simple structure, it can be opened and closed quickly (the stopper can be opened and closed by turning the plug for a quarter of a turn), the operation is convenient, and the fluid resistance is small. At present, it is mainly used in low pressure, low temperature and medium temperature situations.
