Triple offset butterfly valve for piping systems

Triple offset butterfly valve is a high-performance butterfly valve that has excellent sealing and wear resistance. The feature of a triple offset butterfly valve is that there is no friction between the seat and the disc, which can effectively extend the service life. The structure of a triple offset butterfly valve is as follows:

  • First offset: The eccentricity of the stem and the disc centerline, which prevents the disc from scraping the seat during opening and closing.
  • Second offset: The eccentricity of the stem and the body centerline, which enables the disc to fit tightly on the seat when closed, forming a metal-to-metal seal.
  • Third offset: The eccentricity of the seat cone and the body centerline, which creates a conical space between the seat and the disc, increasing the elasticity of the sealing surface and improving the sealing reliability.
