Overview:
      Valve has a small fluid resistance, sealing surface by the impact of erosion is small, does not change the media flow, non-spoiler, low pressure drop characteristics for pressure, wide temperature range, is a common cut-off valve, widely used in petroleum, chemical , power plants and other oil, steam pipeline to connect or disconnect the line of media. (Can not make use of the throttle)
 
 
Manufacturing acceptance of technical standards:
              Manufacturing acceptance of technical conditions prescribed in GB12234.
              Valve structure longitudinal dimension according to the provisions of GB12221.
              Flange size JB79 press or size provided by the user.
 
 
Main features and uses:
