X43F46 Flange Connection Manual Plug Valve (fully lined)

• 

• Feature Description:

  
  

  The plug valve is a valve that uses a plug body with a hole as an opening and closing member to realize an opening and closing action by rotation of the plug body and the valve stem. The plug valve has a simple structure, rapid opening and closing, and low fluid resistance. In recent years, as one of the earliest valves used in history, not only has it not been replaced by new valves such as ball valves, but the market is becoming more and more popular.

  
  

  Plug valve structure features:

  
  

  The inlet and outlet end window of the valve body is designed as a double-channel grooved sealing ring structure. During the rotation of the cock, the sealing ratio between the sealing pairs is gradually changed until it reaches the fully open or fully closed position, and sufficient sealing pressure is generated. The sealing pair reaches zero leakage.

  
  

  The double grooved sealing ring can make the PTFE bushing stabilize the displacement inside the valve body, and absorb the slight deformation caused by the temperature difference, and the force wiping effect between the bushing and the cock is improved. The applicable life of the sealing surface.

  
  

  The upper part of the plug shaft is composed of a PTFE diaphragm and an O-ring and an adjusting washer, which can adjust the sealing specific pressure between the sealing surfaces, make the plug flexible, and ensure the sealing of the inlet and outlet ends and the middle flange connection end.

  
  

  The entire sealing process can be approximated regardless of the pressure inside the pipe.

  
  

  In the PTFE bushing, it is lubricated and has a long service life according to the use temperature and the working medium.
